Using AC adapter and battery----------------------------------------------------------
„ Checking battery status
You can determine the percentage of battery power remaining by checking
the battery icon in the notification area.
Note: As 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:
• The amount of energy stored in the battery when you commence work.
• The way you use your computer: for example, how often you access the hard
disk drive and how bright you make the computer display.
„ Charging the battery
When you find that the battery power is low, you need to charge the battery
or replace it with a fully charged one.
You need to charge the battery in any of the following situations:
• When you purchase a new battery
• If the battery status indicator starts blinking
• If the battery has not been used for a long time
Note:
• You are advised to insert the battery pack when using your computer to prevent small
particles from entering the inside of your computer.
• To increase the life of the battery pack, the computer does not start recharging the
battery immediately after it drops from fully charged.
• Charge the battery at a temperature between 50 °F and 86 °F (10 °C-30 °C).
• Full charge or discharge is not required.

About NVIDIA Optimus (on select models)
-----------------------
Optimus is a GPU switching mechanism which automatically switches the
active GPU to perform image-rendering tasks. If no graphics-intensive
programs are running, the integrated GPU will be selected as the active GPU
to preserve battery life; if you start high-definition movie playback or a 3D
game, the image-rendering task is automatically switched by Optimus to the
discrete GPU to produce high graphics performance.
When Optimus is enabled, switching between integrated and discrete GPUs
is performed automatically without user intervention.

Chapter 3. Connecting to the Internet
Wireless connection----------------------------------------------------------------------------
Wireless connections provide mobile access to the Internet, allowing you to
stay online anywhere the wireless signal covers.
Divided by the signal scales, wireless connection to the Internet can be built
based on the following standards.
Wi-Fi
Wi-Fi networks cover a small physical area, like a home,
office, or small group of buildings. An access point is
necessary for the connection.
WiMAX
WiMAX networks connect several Wireless LAN
systems to cover a metropolitan area, providing high-
speed broadband access without the need for cables.
Mobile Broadband
The Mobile Broadband network provides Internet access
to computers, cell phones and other devices over a large
geographic area. Mobile networks are used for data
transmission, and access is usually provided by a mobile
network operator. A Mobile Broadband SIM card is
necessary for the connection.
Note: Your computer may not support all wireless connection methods.

Chapter 4. OneKey Rescue system
OneKey Rescue system----------------------------------------------------------------------
„ Introduction
The Lenovo OneKey Rescue system is an easy-to-use application that can be
used to back up the data on your system partition (C drive) for easy restore
when required. You can run Lenovo OneKey Recovery under the Windows
operating system, and the OneKey Rescue system without starting the
Windows operating system.
ꢀ Attention:
In order to utilize the features of the OneKey Rescue system, your hard disk
already includes a hidden partition by default to store the system image file
and OneKey Rescue system program files. This default partition is hidden
for security reasons and is the reason the available disk space is less than it
claims. The exact available hard disk space depends on the file size of the
mirror image file (based on the size of operating system and preinstalled
software).
„ Using Lenovo OneKey Recovery (within Windows operating
system)
In Windows operating system, double click the OneKey Recovery system
Icon on the desktop to launch Lenovo OneKey Recovery.
Within the program, you can back up the system partition on the hard disk
drive, other storage devices, or by creating recovery discs.
Note:
• The backup process and creation of recovery discs may take some time, connect the AC
adapter and battery pack to your computer.
• After the recovery discs are burned, please number them so that you can use them in the
correct order.
• Computers without an integrated optical drive support the creation of recovery discs;
however an appropriate external optical drive is needed to physically create the recovery
discs.
For more instructions, see the Help file of Lenovo OneKey Recovery.

Replacing the hard disk drive -----------------------------------------------
You can increase the storage capacity of your computer by replacing the hard
disk drive with one of greater capacity. You can purchase a new hard disk
drive from your reseller or Lenovo marketing representative.
Note:
• Replace the hard disk drive only if you upgrade it or have it repaired. The connectors and
bay of the hard disk drive were not designed for frequent changes, or drive swapping.
• The preinstalled softwares are not included on an optional hard disk drive.
Handling a hard disk drive
•
Do not drop the drive or subject it to physical shocks. Put the drive on a material,
such as soft cloth, that absorbs the physical shock.
•
•
Do not apply pressure to the cover of the drive.
Do not touch the connector.
The drive is very sensitive. Incorrect handling can cause damage and perma-
nent loss of data on the hard disk. Before removing the hard disk drive, make
a backup copy of all the information on the hard disk, and then turn the com-
puter off. Never remove the drive while the system is operating, in sleep
mode, or in hibernation mode.

Replacing memory --------------------------------------------------------------------------
You can increase the amount of memory in your computer by installing a
double-data-rate three synchronous dynamic random access memory (DDR3
SDRAM)-available as an option-in the memory slot of your computer. DDR3
SDRAMs are available in various capacities.
Note:
• Use only the memory types supported by your computer. If you incorrectly install optional
memory, or install an unsupported memory type, a warning beep will sound when you try
to start the computer.
• Select models of the computer may have only one memory slot. Refer to the actual product.
However, the procedure for replacing the memory is the same as listed below.
To install a DDR3 SDRAM, do the following:
1
Touch a metal table or a grounded metal object to reduce any static elec-
tricity in your body, which could damage the DDR3 SDRAM. Do not
touch the contact edge of the DDR3 SDRAM.
2
Turn off the computer. Disconnect the AC adapter and all cables from the
computer.
