Important safety information  
This information can help you safely use your IBM® personal computer. Follow  
and retain all information included with your IBM computer. The information in  
this document does not alter the terms of your purchase agreement or the IBM  
Statement of Limited Warranty.  
Customer safety is important to IBM. 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 mobile personal computers, IBM ships some products (such as speakers  
or monitors) with external power adapters. If you have such a product, this  
information applies to your product. In addition, your computer product may  
contain a coin-sized internal battery that provides power to your system clock even  
when the machine is unplugged, so the battery safety information applies to all  
computers.  
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 machine. 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.  
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 IBM 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 conditions listed below, 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 IBM Support Center for further guidance.  
v Power cords, plugs, power adapters, extension cords, surge protectors, or power  
supplies that are cracked, broken or damaged.  
v Signs of overheating, smoke, sparks or fire.  
© Copyright IBM Corp. 2004  
v
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
v Damage to a battery (such as cracks, dents, creases), discharge from a battery, or  
a buildup of foreign substances on the battery.  
v A cracking, hissing or popping sound, or strong odor that comes from the  
product.  
v Signs that liquid has been spilled or an object has fallen onto the computer  
product, the power cord or power adapter.  
v The computer product, the power cord or power adapter has been exposed to  
water.  
v The product has been dropped or damaged in any way.  
v The product does not operate normally when you follow the operating  
instructions.  
Note: If you notice these conditions with a non-IBM product (such as an extension  
cord), stop using that product until you can contact the product manufacturer for  
further instructions, or until you get a suitable replacement.  
General safety guidelines  
Always observe the following precautions to reduce the risk of injury and property  
damage.  
Service  
Do not attempt to service a product yourself unless instructed to do so by the IBM  
Support Center. Use only an IBM authorized service provider who is approved to  
repair your particular product.  
Note: Some parts can be upgraded or replaced by the customer. These parts are  
referred to as Customer Replaceable Units, or CRUs. IBM expressly identifies CRUs  
as such, and provides documentation with instructions when it is appropriate for  
customers to replace those parts. You must closely follow all instructions when  
performing such replacements. Always make sure that the power is turned off and  
that the product is unplugged from any power source before you attempt the  
replacement. If you have any questions or concerns, contact the IBM Support  
Center.  
Power cords and power adapters  
Use only the power cords and power adapters supplied by the product  
manufacturer.  
Never wrap a power cord around the 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 the cord and power adapters from liquids. For instance, do not leave your  
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 cord or power  
adapter has been stressed by misuse. Liquids can also cause gradual corrosion of  
the power cord terminals and/or the connector terminals on the adapter which can  
eventually result in overheating.  
vi User Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
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 and/or  
shows signs of overheating (such as deformed plastic) at the ac input 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.  
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  
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.  
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.  
Connect and disconnect the equipment from the electrical outlet carefully  
Batteries  
All IBM personal computers contain a non-rechargeable coin cell battery to provide  
power to the system clock. In addition many mobile products such as Thinkpad  
notebook PCs utilize a rechargeable battery pack to provide system power when in  
portable mode. Batteries supplied by IBM for use with your product have been  
tested for compatibility and should only be replaced with IBM 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.  
Important safety information vii  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
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 your battery is  
damaged, or if you notice any discharge from your battery or the buildup of  
foreign materials on the battery leads, stop using the battery and obtain a  
replacement from the battery manufacturer.  
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.  
Heat and product ventilation  
Computers generate heat when turned on and when batteries are charging.  
Notebook PCs can generate a significant amount of heat due to their compact size.  
Always follow these basic precautions:  
v Do not leave the base of your computer in contact with your lap or any part of  
your body for an extended period when the computer is functioning or when  
the battery is charging. Your computer produces some heat during normal  
operation. Extended contact with the body could cause discomfort or, potentially,  
a skin burn.  
v Do not operate your computer or charge the battery near flammable materials or  
in explosive environments.  
v 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.  
CD and DVD drive safety  
CD and DVD drives spin discs at a high speed. If a CD or DVD is cracked or  
otherwise physically damaged, it is possible for the disc to break apart or even  
shatter when the CD drive is in use. To protect against possible injury due to this  
situation, and to reduce the risk of damage to your machine, do the following:  
v Always store CD/DVD discs in their original packaging  
v Always store CD/DVD discs out of direct sunlight and away from direct heat  
sources  
v Remove CD/DVD discs from the computer when not in use  
v Do not bend or flex CD/DVD discs, or force them into the computer or their  
packaging  
v Check CD/DVD discs for cracks before each use. Do not use cracked or

v Prevent others from touching components.  
v When you install a new option, touch the static-protective package containing  
the option to a metal expansion-slot cover or other unpainted metal surface on  
the computer for at least two seconds. This reduces static electricity in the  
package and your body.  
v When possible, remove the option and install it directly in the computer without  
setting the option down. When this is not possible, place the static-protective  
package that the option came in on a smooth, level surface and place the option  
on it.  
v Do not place the option on the computer cover or other metal surface.  
Installing external options  
This section shows the various external connectors on your computer to which you  
can attach external options, such as external speakers, a printer, or a scanner. For  
some external options, you must install additional software in addition to making

v Prevent others from touching components.  
v When you install a new option, touch the static-protective package containing  
the option to a metal expansion-slot cover or other unpainted metal surface on  
the computer for at least two seconds. This reduces static electricity in the  
package and your body.  
v When possible, remove the option and install it directly in the computer without  
setting the option down. When this is not possible, place the static-protective  
package that the option came in on a smooth, level surface and place the option  
on it.  
v Do not place the option on the computer cover or other metal surface.  
Installing external options

instructions that come with the option.  
Handling static-sensitive devices  
Static electricity, although harmless to you, can seriously damage computer  
components and options.  
When you add an option, do not open the static-protective package containing the  
option until you are instructed to do so.  
When you handle options and other computer components, take these precautions  
to avoid static electricity damage:  
v Limit your movement. Movement can cause static electricity to build up around  
you.

v Always handle components carefully. Handle adapters and memory modules by  
the edges. Never touch any exposed circuitry.  
v Prevent others from touching components.  
v When you install a new option, touch the static-protective package containing  
the option to a metal expansion-slot cover or other unpainted metal surface on  
the computer for at least two seconds. This reduces static electricity in the  
package and your body.  
v When possible, remove the option and install it directly in the computer without  
setting the option down. When this is not possible, place the static-protective  
package that the option came in on a smooth, level surface and place the option  
on it.  
v Do not place the option on the computer cover or other metal surface.  
Installing external options  
This section shows the various external connectors on your computer to which you  
can attach external options, such as external speakers, a printer, or a scanner. For  
some external options, you must install additional software in addition to making  
the physical connection. When adding an external option, use the information in  
this section to identify the required connector, and then use the instructions that  
come with the option to help you make the connection and install any software or  
device drivers that are required for the option.

Appendix A. Updating system programs  
This appendix contains information about updating system programs and how to  
recover from a POST/BIOS update failure.  
System programs  
System programs are the basic layer of software that is built into your computer.  
They include the power-on self-test (POST), the basic input/output system (BIOS)  
code, and the IBM Setup Utility program. POST is a set of tests and procedures  
that is performed each time you turn on your computer. BIOS is a layer of  
software that translates instructions from other layers of software into electrical  
signals that the computer hardware can understand. You can use the IBM Setup  
Utility program to view and change the configuration and setup of your computer.  
Your computer system board has a module called electrically erasable programmable  
read-only memory (EEPROM, also referred to as flash memory). You can easily update  
POST, BIOS, and the IBM Setup Utility program by starting your computer using a  
flash update diskette or by running a special update program from your operating  
system.  
IBM might make changes and enhancements to the system programs. When  
updates are released, they are available as downloadable files on the World Wide  
Web (see the Quick Reference). Instructions for using the system program updates  
are available in a .txt file that is included with the update files. For most models,  
you can download either an update program to create a system-program-update  
(flash) diskette or an update program that can be run from the operating system.  
Updating (flashing) BIOS from a diskette  
1. Insert a system program update (flash) diskette into the diskette drive (drive A)  
in your computer. System program updates are available at  
http://www.ibm.com/pc/support/ on the World Wide Web.  
2. Turn on the computer. If it is on already, you must turn it off and back on  
again. The update begins.  
Updating (flashing) BIOS from your operating system  
Note: Due to constant improvements being made to the IBM Web site, Web page  
content (including the links referenced in the following procedure) is subject  
to change.  
1. From your browser, type http://www.pc.ibm.com/support in the address field  
and press Enter.  
2. Locate the Downloadable files for your machine type.  
3. Under Select your product, choose your machine type and click Go.  
4. In Downloadable file by category, click BIOS.  
5. Under Download files - BIOS by date, click your machine type.  
6. Scroll down and look for a .txt file that has instructions for Flash BIOS update  
from the operating system. Click the .txt file.  
7. Print these instructions. This is very important since they are not on the screen  
after the download begins.

Download from Www.Somanuals.com. All Manuals Search And Download.  
 
8. From your browser, Click Back to return to the list of files. Carefully follow the  
printed instructions to download, extract, and install the update.  
Recovering from a POST/BIOS update failure  
If power to your computer is interrupted while POST/BIOS is being updated (flash  
update), your computer might not restart correctly. If this happens, perform the  
following procedure (also known as a Boot-block Recovery):  
1. Turn off the computer and any attached devices, such as printers, monitors,  
and external drives.  
2. Unplug all power cords from electrical outlets, and remove the cover. See  
Removing the cover in the chapter for your model.  
3. Locate the Clear CMOS/Recovery jumper on the system board. See  
Identifying parts on the system board in the chapter for your model type.  
4. If necessary, refer to Installing adapters to remove any adapters that impede  
access to the Clear CMOS/Recovery jumper.  
5. Move the jumper from the standard position (pins 1 and 2) to pins 2 and 3.  
6. Replace the cover. See Replacing the cover and connecting the cables in the  
chapter for your model type.  
7. Reconnect the power cords for the computer and monitor to electrical outlets.  
8. Insert the POST/BIOS update (flash) diskette into drive A, and turn on the  
computer and the monitor.  
9. After the update session is completed, there will be no video and the series of  
beeps will end. Remove the diskette from the diskette drive, and turn off the  
computer and monitor.  
10. Unplug the power cords from electrical outlets.  
11. Remove the cover. See Removing the cover in the chapter for your model  
type.  
12. Remove any adapters that impede access to the BIOS Configuration jumper.  
13. Replace the Clear CMOS/Recovery jumper to its original position.  
14. Replace any adapters that were removed.  
15. Replace the cover and reconnect any cables that were disconnected.  
16. Turn on the computer to restart the operating system.

Appendix B. Cleaning the mouse  
This appendix provides instructions on how to clean your mouse. The procedure  
will be different depending on which type of mouse you have.  
Cleaning an optical mouse  
If you experience some problems with your optical mouse, check the following:  
1. Turn the mouse over and look carefully at the lens area.  
a. If there is a smudge on the lens, gently clean the area with a plain cotton  
swab or plain q-tip.  
b. If there is some debris in the lens, gently blow the debris away from the  
area.  
2. Check the surface you are using the mouse on. If you have a very intricate  
picture or pattern beneath the mouse it is difficult for the digital signal  
processor (DSP) to determine changes in the mouse position.  
Cleaning a mouse with a ball  
If the pointer on the screen does not move smoothly with the mouse, you might  
need to clean the mouse.  
Note: The following illustration might be slightly different from your mouse.  
ꢀ1ꢁ Retainer ring  
ꢀ2ꢁ Ball  
ꢀ3ꢁ Plastic rollers  
ꢀ4ꢁ Ball cage  
To clean a mouse with a ball:  
1. Turn off your computer.  
2. Turn the mouse over, with the top side down, and look carefully at the bottom.  
Twist the retainer ringꢀ1ꢁto the unlocked position to remove the ball.

3. Place your hand over the retainer ring and ballꢀ2ꢁ, and then turn the mouse  
over, top side up, so that the retainer ring and ball fall out into your hand.  
4. Wash the ball in warm, soapy water then dry it with a clean cloth. Blow air  
carefully into the ball cageꢀ4ꢁto dislodge dust and lint.  
5. Look for a build up of dirt on the plastic rollersꢀ3ꢁinside the ball cage. This  
build up usually appears as a stripe running across the middle of the rollers.  
6. If the rollers are dirty, clean them by using a cotton swab soaked in isopropyl  
(rubbing) alcohol. Turn the rollers with your finger and continue swabbing  
them until all the dirt is removed. Be sure the rollers are still centered in their  
channels after you clean them.  
7. Remove any fibers from the swab that might be remaining on the rollers.  
8. Replace the ball and the retainer ring.  
9. Turn your computer back on.

Appendix C. Manual modem commands  
The following section lists commands for manually programming your modem.  
Commands are accepted by the modem while it is in Command Mode. Your  
modem is automatically in Command Mode until you dial a number and establish  
a connection. Commands may be sent to your modem from a PC running  
communication software or any other terminal devices.  
All commands sent to the modem must begin with AT and end with ENTER. All  
commands may be typed in either upper or lower case, but not mixed. To make  
the command line more readable, spaces may be inserted between commands. If  
you omit a parameter from a command that requires one, it is just like specifying a  
parameter of 0.
