Read this first  
Be sure to follow the important tips given here to get the most use and enjoyment out of your computer.  
Failure to do so might lead to discomfort or injury, or cause your computer to fail.  
Protect yourself from the heat that your computer generates.  
When your computer is turned on or the battery is charging, the base, the palm  
rest, and some other parts may become hot. The temperature they reach  
depends on the amount of system activity and the level of charge in the battery.  
Extended contact with your body, even through clothing, could cause  
discomfort or even a skin burn.  
• Avoid keeping your hands, your lap, or any other part of your body in  
contact with a hot section of the computer for any extended time.  
• Periodically take hands from using the keyboard by lifting your hands from  
the palm rest.  
Protect yourself from the heat generated by the ac power adapter.  
When the ac power adapter is connected to an electrical outlet and your  
computer, it generates heat.  
Extended contact with your body, even through clothing, may cause a skin  
burn.  
• Do not place the ac power adapter in contact with any part of your body  
while it is in use.  
• Never use it to warm your body.  
Prevent your computer from getting wet.  
To avoid spills and the danger of electrical shock, keep liquids away from your  
computer.  
Protect the cables from being damaged.  
Applying strong force to cables may damage or break them.  
Route communication lines, or the cables of an ac power adapter, a mouse, a  
keyboard, a printer, or any other electronic device, so that they cannot be walked  
on, tripped over, pinched by your computer or other objects, or in any way  
subjected to treatment that could interfere with the operation of your computer.

• Before putting your computer in a carrying case, ensure that it is off, in sleep  
mode, or in hibernation mode. Do not put a computer in a carrying case while it  
is turned on.  
• Do not carry your computer in notebook mode, stand mode, tablet mode, or tent  
mode. Carry your computer with the display closed only.  
Important safety information  
Note: Read the important safety information first.  
This information can help you safely use your notebook computer. Follow and retain all information included  
with your computer. The information in this document does not alter the terms of your purchase agreement  
or the Lenovo® Limited Warranty. For more information, see “Warranty Information” in the Safety, Warranty,  
and Setup Guide that comes with your computer.  
Customer safety is important. Our products are developed to be safe and effective. However, personal  
computers are electronic devices. Power cords, power adapters, and other features can create potential  
safety risks that can result in physical injury or property damage, especially if misused. To reduce these  
risks, follow the instructions included with your product, observe all warnings on the product and in the  
operating instructions, and review the information included in this document carefully. By carefully following  
the information contained in this document and provided with your product, you can help protect yourself  
from hazards and create a safer computer work environment.  
Note: This information includes references to power adapters and batteries. In addition to notebook  
computers, some products (such as speakers and monitors) ship with external power adapters. If you have

Conditions that require immediate action  
Products can become damaged due to misuse or neglect. Some product damage is serious enough  
that the product should not be used again until it has been inspected and, if necessary, repaired by  
an authorized servicer.  
As with any electronic device, pay close attention to the product when it is turned on. On very rare  
occasions, you might notice an odor or see a puff of smoke or sparks vent from your product. Or you  
might hear sounds like popping, cracking or hissing. These conditions might merely mean that an  
internal electronic component has failed in a safe and controlled manner. Or, they might indicate  
a potential safety issue. However, do not take risks or attempt to diagnose the situation yourself.  
Contact the Customer Support Center for further guidance. For a list of Service and Support phone  
numbers, see the following Web site:  
http://www.lenovo.com/support/phone  
Frequently inspect your computer and its components for damage or wear or signs of danger. If you  
have any question about the condition of a component, do not use the product. Contact the Customer  
Support Center or the product manufacturer for instructions on how to inspect the product and  
have it repaired, if necessary.  
In the unlikely event that you notice any of the following conditions, or if you have any safety concerns  
with your product, stop using the product and unplug it from the power source and telecommunication  
lines until you can speak to the Customer Support Center for further guidance.  
• Power cords, plugs, power adapters, extension cords, surge protectors, or power supplies that are  
cracked, broken, or damaged.  
• Signs of overheating, smoke, sparks, or fire.  
• Damage to a battery (such as cracks, dents, or creases), discharge from a battery, or a buildup of foreign  
substances on the battery.  
• A cracking, hissing or popping sound, or strong odor that comes from the product.  
• Signs that liquid has been spilled or an object has fallen onto the computer product, the power cord or  
power adapter.  
• The computer product, power cord, or power adapter has been exposed to water.  
• The product has been dropped or damaged in any way.  
• The product does not operate normally when you follow the operating instructions.  
Note: If you notice these conditions with a product (such as an extension cord) that is not manufactured for  
or by Lenovo, stop using that product until you can contact the product manufacturer for further instructions,  
or until you get a suitable replacement.  
Safety guidelines  
Always observe the following precautions to reduce the risk of injury and property damage.  
Service and upgrades  
Do not attempt to service a product yourself unless instructed to do so by the Customer Support Center or  
your documentation. Only use a Service Provider who is approved to repair your particular product.  
Note: Some computer parts can be upgraded or replaced by the customer. Upgrades typically are  
referred to as options. Replacement parts approved for customer installation are referred to as Customer  
Replaceable Units, or CRUs. Lenovo provides documentation with instructions when it is appropriate for  
customers to install options or replace CRUs. You must closely follow all instructions when installing or  
replacing parts. The Off state of a power indicator does not necessarily mean that voltage levels inside a  
product are zero. Before you remove the covers from a product equipped with a power cord, always ensure  
© Copyright Lenovo 2013  
v
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
that the power is turned off and that the product is unplugged from any power source. If you have any  
questions or concerns, contact the Customer Support Center.  
Although there are no moving parts in your computer after the power cord has been disconnected, the  
following warnings are required for your safety.  
CAUTION:  
Hazardous moving parts. Keep fingers and other body parts away.  
CAUTION:  
Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer  
cool before opening the cover.  
Power cords and power adapters  
DANGER  
Use only the power cords and power adapters supplied by the product manufacturer.  
The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G, 0.75 mm2, or  
better. For other countries, the suitable types shall be used accordingly.  
Never wrap a power cord around a power adapter or other object. Doing so can stress the cord in  
ways that can cause the cord to fray, crack, or crimp. This can present a safety hazard.  
Always route power cords so that they will not be walked on, tripped over, or pinched by objects.  
Protect power cords and power adapters from liquids. For instance, do not leave your power cord  
or power adapter near sinks, tubs, toilets, or on floors that are cleaned with liquid cleansers.  
Liquids can cause a short circuit, particularly if the power cord or power adapter has been stressed  
by misuse. Liquids also can cause gradual corrosion of power cord terminals and/or the connector  
terminals on a power adapter, which can eventually result in overheating.  
Always connect power cords and signal cables in the correct order and ensure that all power cord  
connectors are securely and completely plugged into receptacles.  
Do not use any power adapter that shows corrosion at the ac input pins or shows signs of  
overheating (such as deformed plastic) at the ac input pins or anywhere on the power adapter.  
Do not use any power cords where the electrical contacts on either end show signs of corrosion or  
overheating or where the power cord appears to have been damaged in any way.  
vi User Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
To prevent possible overheating, do not cover the power adapter with clothing or other objects  
when the power adapter is plugged into an electrical outlet.  
Extension cords and related devices  
Ensure that extension cords, surge protectors, uninterruptible power supplies, and power strips that you use  
are rated to handle the electrical requirements of the product. Never overload these devices. If power strips  
are used, the load should not exceed the power strip input rating. Consult an electrician for more information  
if you have questions about power loads, power requirements, and input ratings.  
Plugs and outlets  
DANGER  
If a receptacle (power outlet) that you intend to use with your computer equipment appears to be  
damaged or corroded, do not use the outlet until it is replaced by a qualified electrician.  
Do not bend or modify the plug. If the plug is damaged, contact the manufacturer to obtain  
a replacement.  
Do not share an electrical outlet with other home or commercial appliances that draw large amounts  
of electricity; otherwise, unstable voltage might damage your computer, data, or attached devices.  
Some products are equipped with a three-pronged plug. This plug fits only into a grounded  
electrical outlet. This is a safety feature. Do not defeat this safety feature by trying to insert it into  
a non-grounded outlet. If you cannot insert the plug into the outlet, contact an electrician for an  
approved outlet adapter or to replace the outlet with one that enables this safety feature. Never  
overload an electrical outlet. The overall system load should not exceed 80 percent of the branch  
circuit rating. Consult an electrician for more information if you have questions about power loads  
and branch circuit ratings.  
Be sure that the power outlet you are using is properly wired, easily accessible, and located close  
to the equipment. Do not fully extend power cords in a way that will stress the cords.  
Be sure that the power outlet provides the correct voltage and current for the product you are  
installing.  
Carefully connect and disconnect the equipment from the electrical outlet.

attached. There are no serviceable parts inside these components. If you suspect a problem with  
one of these parts, contact a service technician.  
External devices  
CAUTION:  
Do not connect or disconnect any external device cables other than USB cable while the computer  
power is on; otherwise, you might damage your computer. To avoid possible damage to attached  
devices, wait at least five seconds after the computer is shut down to disconnect external devices.  
General battery notice  
DANGER  
Personal computers manufactured by Lenovo contain a coin cell battery to provide power to  
the system clock. In addition, many mobile products, such as notebook computers, utilize a  
rechargeable battery pack to provide system power when in portable mode. Batteries supplied by  
Lenovo for use with your product have been tested for compatibility and should only be replaced  
with approved parts.  
Never attempt to open or service any battery. Do not crush, puncture, or incinerate batteries or  
short circuit the metal contacts. Do not expose the battery to water or other liquids. Only recharge  
the battery pack strictly according to instructions included in the product documentation.  
Battery abuse or mishandling can cause the battery to overheat, which can cause gasses or flame  
to “vent” from the battery pack or coin cell. If you notice any signs of bulging, leakage or corrosion  
on the exterior of the product, this may be the result of an internal battery fault. If this occurs, stop  
using the product immediately and please contact the Lenovo Support team for further instructions.  
Factory replacement of the batteries may be required.  
Batteries can degrade when they are left unused for long periods of time. For some rechargeable  
batteries (particularly Lithium Ion batteries), leaving a battery unused in a discharged state could  
increase the risk of a battery short circuit, which could shorten the life of the battery and can also  
pose a safety hazard. Do not let rechargeable Lithium-Ion batteries completely discharge or store  
these batteries in a discharged state.  
Do not attempt to replace the internal batteries:  
Replacement of any batteries inside of your computer must be done by a Lenovo-authorized repair facility  
or a Lenovo-authorized technician. The Lenovo-authorized repair facilities or technicians recycle Lenovo  
batteries according to local laws and regulations.

the keyboard for any extended length of time.  
• Do not operate your computer or charge the battery near flammable materials or in explosive  
environments.  
• Ventilation slots, fans and/or heat sinks are provided with the product for safety, comfort, and  
reliable operation. These features might inadvertently become blocked by placing the product on  
a bed, sofa, carpet, or other flexible surface. Never block, cover, or disable these features.  
• When the ac power adapter is connected to an electrical outlet and your computer, it generates  
heat. Do not place the adapter in contact with any part of your body while using it. Never use the  
ac power adapter to warm your body. Extended contact with your body, even through clothing,  
may cause a skin burn.  
For your safety, always follow these basic precautions with your computer:  
• Keep the cover closed whenever the computer is plugged in.  
• Regularly inspect the outside of the computer for dust accumulation.  
• Remove dust from vents and any perforations in the bezel. More frequent cleanings might be  
required for computers in dusty or high-traffic areas.  
• Do not restrict or block any ventilation openings.  
• Do not operate your computer inside furniture, as this might increase the risk of overheating.

Power management  
When you use your computer away from electrical outlets, you depend on battery power to keep your  
computer running. Different computer components consume power at different rates. The more you use the  
power-intensive components, the faster you consume battery power.  
Spend more time unplugged with ThinkPad batteries. Mobility has revolutionized business by enabling  
you to take your work wherever you go. With ThinkPad batteries, you will be able to work longer without  
being tied to an electrical outlet.  
Checking the battery status  
The battery status icon in the Windows notification area displays the percentage of battery power remaining.  
The rate at which you use battery power will determine how long you can use the battery of your computer  
between charges. Because each computer user has different habits and needs, it is difficult to predict how  
long a battery charge will last. There are two main factors:  
• How much energy is stored in the battery when you begin to work.  
• The way you use your computer. For example:  
– How often you access the hard disk drive or solid-state drive.  
Chapter 2. Using your computer 33  
Download from Www.Somanuals.com. All Manuals Search And Download.  
   
– How bright you make the computer display.  
– How often you use the wireless features.  
To check for detailed battery status information, open the Lenovo Settings program and click Power.  
Using the ac power adapter  
The power to run your computer can come either from the lithium-ion (Li-ion) battery pack of your computer,  
or from ac power through the ac power adapter. While you use ac power, the battery charges automatically.  
The ac power adapter that comes with your computer has two basic components:  
• The transformer pack that converts ac power for use with the computer.  
• The power cord that plugs into the ac outlet and into the transformer pack.  
Attention: Using an improper power cord could cause severe damage to your computer.  
Connecting the ac power adapter  
To connect the ac power adapter, do the following:  
Note: Ensure that you perform the actions in the order in which they are listed.  
1. Connect the power cord to an electrical outlet.  
2. Connect the power cord to the transformer pack.  
3. Connect the ac power adapter to the power jack of the computer.  
Tips on using the ac power adapter  
You can check the status of your battery at any time by looking at the battery meter at the bottom of your  
display.  
• When the ac power adapter is not in use, disconnect it from the electrical outlet.  
• Do not bind the power cord tightly around the ac power adapter transformer pack when it is connected to  
the transformer.  
• Before you charge the battery, make sure that its temperature is at least 10°C (50°F).  
You can charge the battery when the ac power adapter is connected to the computer and the battery is  
installed. You need to charge the battery in any of the following conditions:  
– When you purchase a new battery  
– When the battery meter at the bottom of your display shows that the battery power remaining is low.  
– If the battery has not been used for a long time  
Charging the battery  
When you check battery status and find that the percentage of power remaining is low or when the power  
alarm alerts you that the remaining power is low, you need to charge your battery or replace it with a  
charged battery.  
If an ac outlet is convenient, plug the ac power adapter into it, and then insert the jack into the computer.  
The battery will be fully charged in about three to six hours. This is affected by the battery size and the  
physical environment. The battery status indicator will let you know that the battery is charging, and will  
also notify you when the battery is fully charged.  
Note: To maximize the life of the battery, the computer does not start recharging the battery if the remaining  
power is greater than 95%.

Accessibility and comfort  
Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort.  
Arrange your workplace and the equipment you use to suit your individual needs and the kind of work  
that you perform. In addition, use healthy work habits to maximize your performance and comfort while  
using your computer.  
The following topics provide information about arranging your work area, setting up your computer  
equipment, and establishing healthy work habits.  
Lenovo is committed to providing the latest information and technology to our customers with disabilities.  
Refer to our accessibility information which outlines our efforts in this area. See “Accessibility information”  
on page 44.  
Ergonomic information  
Working in the virtual office might mean adapting to frequent changes in your environment. Following some  
simple rules will make things easier and bring you the maximum benefits of your computer. Keeping in mind  
such basics as good lighting and proper seating, for example, can help you improve your performance  
and achieve greater comfort.  
This example shows someone in a conventional setting. Even when not in such a setting, you can follow  
many of these tips. Develop good habits, and they will serve you well.  
General posture: Make minor modifications in your working posture to deter the onset of discomfort caused  
by long periods of working in the same position. Frequent short breaks from your work also help to prevent  
minor discomfort associated with your working posture.

Display: Position the display to maintain a comfortable viewing distance of 510-760 mm (20-30 inches).  
Avoid glare or reflections on the display from overhead lighting or outside sources of light. Keep the display  
screen clean and set the brightness to levels that enable you to see the screen clearly. Press F5 or F6  
to adjust display brightness.  
Head position: Keep your head and neck in a comfortable and neutral (vertical, or upright) position.  
Chair: Use a chair that gives you good back support and seat height adjustment. Use chair adjustments to  
best suit your desired posture.  
Arm and hand position: If available, use chair arm rests or an area on your working surface to provide  
weight support for your arms. Keep your forearms, wrists, and hands in a relaxed and neutral (horizontal)  
position. Type with a soft touch without pounding the keys.  
Leg position: Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest.  
What if you are traveling?  
It might not be possible to observe the best ergonomic practices when you are using your computer  
while on the move or in a casual setting. Regardless of the setting, try to observe as many of the tips as  
possible. Sitting properly and using adequate lighting, for example, will help you maintain desirable levels  
of comfort and performance.  
Questions about vision?  
The visual display screens of ThinkPad notebook computers are designed to meet the highest standards  
and to provide you with clear, crisp images and large, bright displays that are easy to see, yet easy on the  
eyes. Of course, any concentrated and sustained visual activity can be tiring. If you have questions on eye  
fatigue or visual discomfort, consult a vision care specialist for advice.  
Comfort  
Observe the following guidelines to achieve greater comfort and improve performance.  
Active sitting and rest breaks: The longer you sit and work with your computer, the more important it is to  
observe your working posture. Follow “Ergonomic information” on page 43 and practice “active sitting” to  
avoid discomfort associated with your working postures. Making minor voluntary postural changes and  
taking short frequent work breaks are the key ingredients for healthy computing. Your computer is light and  
mobile; you can easily reposition your working surface to accommodate many posture modifications.  
Work area setup options: Familiarize yourself with all of your office furniture so that you know how to  
adjust your work surface, seat, and other work tools to accommodate your preferences for comfort.  
If your work area is not in an office setting, be sure to take special note of employing active sitting  
and taking work breaks. Many ThinkPad product solutions are available to help you modify and expand  
your computer to best suit your needs. Access the following Web site to view some of these options:

Hard disk passwords  
The following two types of hard disk passwords can help protect the information stored on the hard disk drive:  
User hard disk password  
If a user hard disk password has been set, but no master hard disk password has been, the user must  
enter the user hard disk password to access files and applications on the hard disk drive.  
Master hard disk password  
The master hard disk password also requires a user hard disk password. The master hard disk password  
is usually set and used by a system administrator. It enables the administrator to access any hard disk  
drive in a system like a master key. The administrator sets the master password; then assigns a user  
password for each computer in the network. The user can then change the user password as desired, but  
the administrator still can get access by using the master password.  
When a master hard disk password is set, only the administrator can remove the user hard disk password.

a. When a window for typing the new password opens, type your new password in the Enter New  
Password field and press Enter.  
b. In the Confirm New Password field, retype the password you just entered and press Enter.  
• If you select User + Master, do the following:  
a. First, set a user hard disk password. When a message window prompts you to set the user hard  
disk password, press Enter to continue. Type your new user hard disk password in the Enter  
New Password field and press Enter. Retype the password in the Confirm New Password  
field and press Enter.  
b. Then, set a master hard disk password. When a message window prompts you to set the master  
hard disk password. Press Enter to continue. Type your new master hard disk password in the  
Enter New Password field and press Enter. Retype the password in the Confirm New Password  
field and press Enter.

and master hard disk passwords, Lenovo cannot reset your passwords or recover data from the hard disk  
drive. You must take your computer to a Lenovo reseller or a marketing representative to have the hard  
disk drive replaced. Proof of purchase is required, and a fee will be charged for parts and service.  
Hard disk security  
To protect passwords from unauthorized security attacks, refer to the following tips to maximize security:  
• Set a power-on password as well as a hard disk password for your internal solid-state drive or hard disk  
drive. Refer to the procedures in “Power-on password” on page 47 and “Hard disk passwords” on page

Notice on deleting data from your hard disk drive or solid-state drive  
Some of the data stored on the hard disk drive or solid-state drive might be sensitive. Handing your  
computer over to someone else without deleting the installed software, such as operating systems and  
application software, might even violate license agreements. Be sure to delete data stored on the hard disk  
drive or solid-state drive before you dispose of, sell, or hand over your computer.  
You can use the following methods to delete data from the hard disk drive or solid-state drive:  
• Move the data to the Recycle Bin, and then empty the Recycle Bin.  
• Delete the data.  
• Format your hard disk drive or solid-state drive, using the software for initializing it.  
• Use the recovery program provided by Lenovo to bring the hard disk drive or solid-state drive back to  
the factory default settings.  
These operations, however, only change the file location of the data; they do not delete the data itself. In  
other words, the data retrieval processing is disabled under an operating system such as Windows. The  
Chapter 4. Security 53

data is still there, even though it seems to be lost. Thus, it is sometimes possible to read the data by use of  
special software for data recovery. There is a risk that people of bad faith might read and misuse the critical  
data on hard disk drives or solid-state drives for unexpected purposes.  
To prevent leakage of data, it is important that you delete all the data from the hard disk drive when you  
dispose of, sell, or hand over your computer. You can destroy the data physically by smashing the hard disk  
drive with a hammer, or magnetically by means of strong magnetic power, thus making the data unreadable.  
But it is recommended that you use the software (payware) or service (pay service) developed for that  
purpose. The process might take several hours.  
For disposing of data on the solid-state drive, Lenovo provides the Drive Erase Utility for Resetting the  
Cryptographic Key and Erasing the Solid State Drive tool. For disposing of data on the hard disk drive, Lenovo  
provides the Secure Data Disposal tool. Go to http://www.lenovo.com/support to download these tools.  
If an Encryption solid-state drive or a Disk Encryption hard disk drive is supported and installed in your  
computer, you can logically dispose of all the data on the drive in a short time by erasing the cryptographic  
key. The data encrypted with the old key is not physically erased but remains on the drive; however, it cannot  
be decrypted without the old key. This feature is also available with the Drive Erase Utility for Resetting the  
Cryptographic Key and Erasing the Solid State Drive tool.  
Using firewalls  
If your system is preinstalled with a firewall program, it protects against computer Internet security threats,  
unauthorized accesses, intrusions, and Internet attacks. It also protects your privacy.  
For more information about how to use the firewall program, refer to the help information system that  
comes with the program.  
Protecting data against viruses  
Your computer is preinstalled with an antivirus program so you can detect and eliminate viruses. The  
antivirus program is designed to help you detect and eliminate viruses.  
Lenovo provides a full version of antivirus software on your computer with a free 30-day subscription. After  
30 days, you must renew the license to continue receiving the antivirus software updates.  
For more information about how to use your antivirus software, refer to the help information system of  
your antivirus software.

Updating the UEFI BIOS  
The UEFI BIOS is the first program that the computer runs when the computer is turned on. The UEFI BIOS  
initializes the hardware components, and loads the operating system and other programs.  
You can update the UEFI BIOS by starting your computer from a flash update optical disc or a flash update  
program running in the Windows environment. When you install a new program, a device driver, or hardware,  
you might be informed to update the UEFI BIOS.  
For instructions on how to update the UEFI BIOS, go to:  
http://www.lenovo.com/ThinkPadDrivers  
Using system management  
This topic is primarily intended for the network administrators.  
Your computer is designed for manageability, so that you can redirect more resources to better meet your  
business objectives.  
This manageability, known as Total Cost of Ownership (TCO), enables you to remotely operate client  
computers in the same way as you operate your own computer, such as turning on a client computer,  
formatting a hard disk drive, and installing a program.  
Once the computer is configured and operational, you can manage it by using the software and the  
manageability features that are already integrated into the client computer and the network.  
Chapter 7. Advanced configuration 73  
Download from Www.Somanuals.com. All Manuals Search And Download.  
     
Desktop Management Interface  
The UEFI BIOS of your computer supports an interface called System Management BIOS (SMBIOS)  
Reference Specification, version 2.7.1. SMBIOS provides information about the hardware components of  
your computer. It is the responsibility of the UEFI BIOS to provide information about itself and the devices on  
the system board. This specification documents the standards for getting access to this BIOS information.  
Preboot eXecution Environment  
The Preboot eXecution Environment (PXE) technology makes the computer more manageable by enabling  
the computer to start from a server. Your computer supports the personal computer functions that PXE  
requires. For example, with the appropriate LAN card, your computer can be started from the PXE server.  
Note: The Remote Initial Program Load (RIPL or RPL) function cannot be used with your computer.  
Asset ID EEPROM  
The Asset ID EEPROM contains information about the computer configuration and the serial numbers of  
the key components. It also includes a number of blank fields where you can record information about  
the end users in your network.

Chapter 8. Preventing problems  
An important part of owning a ThinkPad notebook computer is maintenance. With proper care, you can  
avoid common problems. The chapter provides information that can help you keep your computer running  
smoothly.  
General tips for preventing problems  
This topic provides the following tips to help you prevent computing problems:  
• If your computer is equipped with both a hard disk drive and an M.2 solid-state drive, you are not  
recommended to use the M.2 solid-state drive as a bootable device. The M.2 solid-state drive is designed  
and developed for “cache” function purpose only. If you use the M.2 solid-state drive as a bootable  
device, its reliability is not guaranteed.  
• Check the capacity of your hard disk drive from time to time. If the hard disk drive gets too full, the  
Windows operating system will slow down and might produce errors. To check the hard disk drive  
capacity, open the File Explorer.  
• Empty your recycle bin on a regular basis.  
• Use disk defragment tool regularly on your hard disk drive to improve data seek and read times.  
To free up disk space, uninstall unused application programs.  
Note: You also might want to look for program duplication or overlapping versions.  
• Clean out your Inbox, Sent, and Trash folders from your e-mail client program.  
• Back up your data at least once a week. If critical data is present, it is a good idea to perform a daily  
backup operation. Lenovo has many backup options available for your computer. Rewritable optical  
drives are available for most machines and are easily installed.  
• Schedule system restore operations to take a system snapshot periodically. For more information about  
system restore, see Chapter 5 “Recovery overview” on page 55.  
• Update device drivers and the UEFI BIOS when needed.  
• Profile your machine at http://www.lenovo.com/support to keep up to date with current drivers and  
revisions.  
• Keep up to date for device drivers on other non-Lenovo hardware. You might want to read the device  
driver information release notes prior to updating for compatibility or known issues.  
• Keep a log book. Entries might include major hardware or software changes, driver updates, minor issues  
you have experienced, and how you resolved the minor issues.  
• If you ever need to run a recovery on your computer to return the preinstalled contents onto the machine,  
the following tips might help along the way:  
– Remove all external devices such as the printer, keyboard, and so on.  
– Make sure that your battery is charged and your computer has the ac power connected.  
– Access ThinkPad Setup and load the default settings.  
– Restart the computer and start the recovery operation.

Download from Www.Somanuals.com. All Manuals Search And Download.  
   
– If your computer uses discs as the recovery media, do not remove the disc from the drive until  
prompted to do so.  
• For suspected hard disk drive issues, refer to “Diagnosing problems” on page 81 and run a diagnostic  
test for the drive before you call the Customer Support Center. If your computer does not start up,  
download the files to create a bootable self-test medium from http://www.lenovo.com/hddtest. Run the  
test and record any messages or error codes. If the test returns any failing error codes or messages,  
call the Customer Support Center with the codes or messages and the computer in front of you. A  
technician will assist you further.  
• If required, you can find the contact information about the Customer Support Center for your country  
or region at http://www.lenovo.com/support/phone. When calling the Customer Support Center, make  
sure that you have your machine model type, serial number, and the computer in front of you. Also, if the  
computer is producing error codes, it is helpful to have the error screen on or the messages written down.  
Making sure device drivers are current  
Device drivers are programs that contain instructions for the operating system about how to operate or  
“drive” a certain piece of hardware. Each hardware component on your computer has its own specific driver.  
If you add a new component, the operating system needs to be instructed on how to operate that piece  
of hardware. After you install the driver, the operating system can recognize the hardware component  
and understand how to use it.  
Note: Because drivers are programs, like any other file on your computer, they are susceptible to corruption  
and might not perform correctly if corruption occurs.  
It is not always necessary to download the latest drivers. However, you should download the latest driver  
for a component if you notice poor performance from that component or if you added a new component.  
This might eliminate the driver as the potential cause of a problem.  
Getting the latest drivers from the Web site  
You can download and install updated device drivers from the Lenovo Web site by doing the following:  
1. Go to http://www.lenovo.com/ThinkPadDrivers.  
2. Select the entry for your computer and then follow the instructions on the screen to download and  
install necessary software.  
Getting the latest drivers using System Update  
The System Update program helps you keep the software on your computer up-to-date. Update packages  
are stored on Lenovo servers and can be downloaded from the Lenovo Support Web site. Update packages  
can contain applications, device drivers, UEFI BIOS flashes, or software updates. When the System Update  
program connects to the Lenovo Support Web site, the System Update program automatically recognizes  
the machine type and model of your computer, the installed operating system, and the language of the  
operating system to determine what updates are available for your computer. The System Update program  
then displays a list of update packages and categorizes each update as critical, recommended, or optional to  
help you understand the importance. You have complete control of which updates to download and install.  
After you select the update packages you want, the System Update program automatically downloads and  
installs the updates without any further intervention from you.  
The System Update program is preinstalled on your computer and is ready to run. The only prerequisite is  
an active Internet connection. You can start the program manually, or you can use the schedule feature  
to enable the program to search for updates automatically at specified intervals. You also can predefine  
scheduled updates to search by severity (critical updates, critical and recommended updates, or all updates)  
so the list you choose from contains only those update types that are of interest to you.

of the program.  
Taking care of your computer  
Although your computer is designed to function reliably in normal work environments, you need to use  
common sense in handling it. By following the important tips in this topic, you will get the most use and  
enjoyment out of your computer.  
Be careful about where and how you work  
• Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic  
bags.  
• Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers  
(more than 13 cm or 5 inches).  
• Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/95°F).  
• Some appliances, such as certain portable desktop fans or air purifiers, can produce negative ions. If a  
computer is close to such an appliance, and is exposed for an extended time to air containing negative  
ions, it might become electrostatically charged. Such a charge might be discharged through your hands  
when you touch the keyboard or other parts of the computer, or through connectors on I/O devices  
connected to the computer. Even though this kind of electrostatic discharge (ESD) is the opposite of a  
discharge from your body or clothing to the computer, it poses the same risk of a computer malfunction.  
Your computer is designed and manufactured to minimize any effects of electrostatic charge. An electrostatic  
charge above a certain limit, however, can increase the risk of ESD. Therefore, when using the computer  
close to an appliance that can produce negative ions, give special attention to the following:  
• Avoid directly exposing your computer to the air from an appliance that can produce negative ions.  
• Keep your computer and peripherals as far as possible from such an appliance.  
• Wherever possible, ground your computer to facilitate safe electrostatic discharge.  
Note: Not all such appliances cause a significant electrostatic charge.  
Be gentle with your computer  
• Avoid placing any objects (including paper) between the display and the keyboard or the palm rest.  
• Do not turn your computer over while the ac power adapter is plugged in. This could break the adapter  
plug.  
Carry your computer properly  
• Before moving your computer, be sure to remove any media, turn off attached devices, and disconnect  
cords and cables.  
• When picking up your open computer, hold it by the bottom. Do not pick up or hold your computer by  
the display.  
Handle storage media and drives properly  
• When installing the hard disk drive, or solid-state drive, follow the instructions shipped with your hardware,  
and apply pressure only where needed on the device.  
Turn off your computer before you replace the hard disk drive or solid-state drive.  
• After you replace the primary hard disk drive or solid-state drive, reattach the cover of the drive slot.  
• Store your external and removable hard disk drives or optical drives in appropriate containers or  
packaging when they are not being used.  
Chapter 8. Preventing problems 77

• Before you install a memory card such as an SD card, SDHC card, SDXC card, and a MultiMediaCard,  
touch a metal table or a grounded metal object. This action reduces any static electricity from your  
body. Static electricity could damage the device.  
• When transferring data to or from a flash media card, such as an SD card, do not put your computer in  
sleep or hibernation mode before the data transfer is complete; otherwise, your data could become  
damaged.  
Taking care in setting passwords  
• Remember your passwords. If you forget a supervisor or hard disk password, Lenovo will not reset it, and  
you might have to replace your system board, hard disk drive, or solid-state drive.  
Registering your computer  
• Register your ThinkPad computer with Lenovo at http://www.lenovo.com/register. For more information,  
Be sure not to modify your computer  
• Only an authorized ThinkPad repair technician should disassemble and repair your computer.  
• Do not modify or tape the latches to keep the display open or closed.  
Cleaning the cover of your computer  
Occasionally clean your computer by doing the following:  
1. Prepare a mixture of a gentle kitchen-use detergent (one that does not contain abrasive powder or  
strong chemicals such as acid or alkaline). Use 5 parts water to 1 part detergent.  
2. Absorb the diluted detergent into a sponge.  
3. Squeeze excess liquid from the sponge.  
4. Wipe the cover with the sponge, using a circular motion and taking care not to let any excess liquid drip.  
5. Wipe the surface to remove the detergent.  
6. Rinse the sponge with clean running water.  
7. Wipe the cover with the clean sponge.  
8. Wipe the surface again with a dry, soft, lint-free cloth.  
9. Wait for the surface to dry completely and remove any fibers from the cloth.  
Cleaning your computer keyboard  
To clean the computer keyboard, do the following:  
1. Apply some isopropyl rubbing alcohol to a soft, dust-free cloth.  
Note: Avoid spraying cleaner directly onto the display or the keyboard.  
2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time,  
the cloth might hook onto an adjacent key and possibly damage it. Ensure that no liquid drips onto  
or between the keys.  
3. Allow to dry.  
4. To remove any crumbs or dust from beneath the keys, you can use a camera blower with a brush  
or cool air from a hair dryer.  
Cleaning your computer display  
To clean the computer display, do the following:  
78 User Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
1. Gently wipe the display with a dry, soft lint-free cloth. If you see a scratchlike mark on your display,  
it might be a stain transferred from the keyboard or the TrackPoint pointing stick when the cover was  
pressed from the outside.  
2. Wipe or dust the stain gently with a soft, dry cloth.  
3. If the stain remains, moisten a soft, lint-free cloth with water or a 50-50 mixture of isopropyl alcohol and  
water that does not contain impurities.  
Note: Avoid spraying cleaner directly onto the display or the keyboard.  
4. Wring out as much of the liquid as you can.  
5. Wipe the display again; do not let any liquid drip into the computer.  
6. Be sure to dry the display before closing it.

Diagnosing problems  
If you experience problems with your computer, use the Lenovo Solution Center program as a starting  
point for solving them.  
The Lenovo Solution Center program enables you to troubleshoot and resolve computer problems. It  
combines diagnostic tests, system information collection, security status, and support information, along  
with hints and tips for maximum system performance.  
Notes:  
• The Lenovo Solution Center program also is available for downloaded at:  
http://www.lenovo.com/diags  
• If you are using other Windows operating system rather than Windows 8.1, you can find the latest  
information about diagnostics for your computer at:  
http://www.lenovo.com/diags  
To run the Lenovo Solution Center program, see “Lenovo programs” on page 12.  
For additional information, refer to the Lenovo Solution Center help system.  
Note: If you are unable to isolate and repair the problem yourself after running the Lenovo Solution Center  
program, save and print the log files created by the program. You will need the log files when you speak to a  
Lenovo technical support representative.  
Troubleshooting  
If your computer has an error, it typically displays a message or an error code, or a beep sounds when  
you turn it on. When you experience a problem, refer to the corresponding sections in this topic to try to  
solve the problem by yourself.  
Computer stops responding  
Print these instructions now and keep the instructions with your computer for reference later.  
If your computer is completely unresponsive (you cannot use the TrackPoint pointing device or the  
keyboard), do the following:  
1. Press and hold the power button for four seconds or more to turn off the computer, and then restart the  
computer by pressing the power button.  
Note: If you cannot turn off your computer, or if you cannot restart it, continue with step 2.

2. Remove the ac power adapter from the computer, and reset the system by inserting a straightened  
paper clip into the emergency reset hole. To locate the reset hole, refer to “Bottom view” on page 6.  
Reattach the ac power adapter.  
Notes:  
a. If the computer does not turn on, continue with step 3.  
b. If the computer starts with ac power but does not start when ac power is disconnected, call the  
Customer Support Center for support. Go to http://www.lenovo.com/support/phone for the latest  
list of support phone numbers for your country or region.  
3. Remove all external devices that are attached to your computer (keyboard, mouse, printer, scanner,  
and so on). Repeat step 2.  
If the computer still does not start up, call the Customer Support Center and a Customer Support Specialist  
will assist you.  
Spills on the keyboard  
With a mobile computer, there are increased chances of spilling liquids on the keyboard. Because most  
liquids conduct electricity, liquid spilled on the keyboard could create numerous short circuits, potentially  
causing irreparable damage to your computer.  
If you spill something on your computer:  
Attention: Ensure that no liquid creates a short circuit between you and the ac power adapter (if in use).  
Although you might lose some data or work by turning off the computer immediately, leaving the computer  
on might make your computer unusable.  
1. Carefully unplug the ac power adapter immediately.  
2. Turn off the computer immediately. The more quickly you stop the current from passing through the  
computer the more likely you will reduce damage from short circuits.  
3. Wait until you are certain that all the liquid is dry before turning on your computer.  
Note: If you want to replace your keyboard, you can purchase a new one.

Problem: A volume or balance slider cannot be moved.  
Solution: The slider might be grayed out. This means that its position is fixed by the hardware and  
cannot be changed.  
Problem: The volume sliders do not stay in place when some audio applications are used.  
Solution: It is normal for the sliders to change position when certain sound applications are used. The  
applications are aware of the settings in the Volume Mixer window and are allowed to change the settings  
themselves. An example is the Windows Media Player. Usually the application has sliders available  
to control the sound from within the application.  
Problem: The balance slider cannot completely mute one channel.  
Solution: The control is designed to compensate for minor differences in balance and does not  
completely mute either channel.  
Problem: There is no volume control for MIDI sound in the Volume Mixer window.  
Solution: Use the hardware volume control. This is because the built-in synthesizer software does  
not support the control.  
Problem: The sound cannot be turned off completely even if you set the Volume Mixer at minimum.  
Solution: You still can hear some sound even though you have set the Volume Mixer control at minimum.  
To turn off the sound completely, go to the Volume Mixer by clicking the speaker icon in the taskbar,  
then click Mixer. Click the Mute Speaker icon.  
Problem: When you connect a headphone to your computer while playing sound, a speaker does not  
produce sound in the MULTI-STREAM mode at Conexant HD Audio Manager.  
Solution: Once the headphone is attached, the streaming is automatically redirected to it. If you want  
to listen to sound from the speakers again, be sure to set those speakers as the default device. The  
procedure is as follows:  
1. Open Control Panel. Click Hardware and Sound.  
2. Click the Conexant HD Audio Manager icon. The Conexant HD Audio Manager window opens.  
3. Look at the tabs of playback devices. If you have attached a headphone, the headphone will be  
automatically set as the default device, and the headphone tab icon will be checked.  
4. To set a different device as the default, click the speaker tab. Click the Set Default Device drop  
down list box. Select Set Default Device. That speaker tab icon will now have a check mark.  
5. Play any sound by use of a music program such as Windows Media Player. Ensure that sound  
comes from the speakers.  
For details, refer to the help information system for Conexant HD Audio Manager.

• Battery Status Profile  
Usage environment and your health  
Integrated wireless cards emit radio frequency electromagnetic energy like other radio devices. However, the  
level of energy emitted is far much less than the electromagnetic energy emitted by wireless devices like  
for example mobile phones.  
Due to the fact that integrated wireless cards operate within the guidelines found in radio frequency safety  
standards and recommendations, Lenovo believes they are safe for use by consumers. These standards and  
recommendations reflect the consensus of the scientific community and result from deliberations of panels  
and committees of scientists who continually review and interpret the extensive research literature.  
In some situation or environment, the use of integrated wireless cards might be restricted by the proprietor  
of the building or responsible representatives of the organization. These situations and areas might for  
example include:  
• Using the integrated wireless cards on board of airplanes, in hospitals or near petrol stations, blasting  
areas (with electro-explosive devices), medical implants or body-worn electronic medical devices, such  
as pace makers.  
• In any other environment where the risk of interference to other devices or services is perceived or  
identified as harmful.  
If you are uncertain of the policy that applies to the use of wireless devices in a specific organization (such as  
airport or hospital), you are encouraged to ask for authorization to use integrated wireless cards prior to  
turning on the computer.  
Location of the UltraConnect wireless antennas  
ThinkPad notebook computers feature an integrated UltraConnectwireless antenna system built into the  
display for optimal reception, enabling wireless communication wherever you are.
