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  
Notes:  
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.

you need to send your computer to Lenovo for service, etc. remove the  
battery pack from the computer. Before removing the battery pack, make  
sure the computer has been shut down.  
Handling the battery  
If the rechargeable battery pack is replaced with an incorrect type, there may  
be danger of an explosion. The battery pack contains a small amount of  
harmful substances. To avoid possible injury and detriment to the  
environment, pay attention to the following points:  
• Replace only with a battery of the type recommended by Lenovo.  
• Keep the battery pack away from fire.  
• Do not expose the battery pack to water or rain.  
• Do not attempt to disassemble the battery pack.

The first time you plug a USB device into a particular USB port on your  
computer, Windows automatically installs a driver for that device. After the  
driver is installed, you can disconnect and reconnect the device without  
performing any additional steps.  
Note: Typically, Windows detects a new device after connecting it, and then installs the  
driver automatically. However, some devices may require you to install the driver  
before connecting. Check the documentation provided by the device’s manufacturer  
before connecting the device.  
Before disconnecting a USB storage device, make sure your computer has  
finished transferring data by that device. Click the Safely Remove Hardware  
icon in the notification area of Windows to remove the device before  
disconnecting.

Thermal management button f  
The thermal management button can be used to switch the computer  
between different work modes and thus control the speed at which the heat  
dissipation fan spins. You can choose between standard, super silent, or  
efficient thermal dissipation mode. You can also activate the dust cleaning  
feature by pressing and releasing the thermal control button.  
Standard mode  
Standard mode is the factory default mode. It is the recommended work  
mode for most programs.  
Super silent mode  
If your computer is not running large programs and you want a silent work  
environment, switch your computer to super silent mode. To switch to super  
silent mode, repeatedly press the thermal management button until  
highlighted. The computer will switch to super silent mode after three  
seconds.  
is  
Note: The heat dissipation fan spins at relatively low speeds in super silent mode, and thus  
dissipates less heat than in other modes. If large programs are running, the system  
may lower the voltage of the CPU (central processing unit) automatically to decrease  
the heat produced by the CPU. Consequently, you might experience lower system  
performance when the computer is running in super silent mode.  
Efficient thermal dissipation mode  
If large programs are running, switch your computer to efficient thermal  
dissipation mode to allow more efficient thermal dissipation. To switch to  
efficient thermal dissipation mode, repeatedly press the thermal  
management button until  
is highlighted.

Chapter 2. Learning the basics  
Performing dust cleaning  
Dust tends to accumulate around the heat sink of the computer’s CPU over  
time, reducing the dissipation capability of the heat sink. You can reduce the  
amount of accumulated dust by performing dust cleaning. To perform dust  
cleaning, repeatedly press the thermal management button until  
highlighted. Dust cleaning will start after three seconds.  
is  
When dust cleaning is activated, the heat dissipation fan spins at high and  
low speed alternatively to allow dust to be discharged. A complete dust  
cleaning process takes several minutes to complete. You can cancel the  
process at any time by switching the computer to standard, super silent or  
efficient thermal dissipation mode.  
Upon completion, the computer returns to the previous mode when dust  
cleaning was activated.  
Note: We recommend you perform dust cleaning at least once a month to reduce the  
amount of dust accumulation around the heat sink. Place your computer in a clean  
environment with good ventilation when performing dust cleaning.

Using passwords  
Using passwords helps prevent your computer from being used by others.  
Once you set a password and enable it, a prompt appears on the screen each  
time you power on the computer. Enter your password at the prompt. The  
computer cannot be used unless you enter the correct password.  
Note: This password can be from one to seven alphanumeric characters in any combination.  
For details about how to set the password, see the Help to the right of the  
screen in BIOS setup utility.  
Note: To enter BIOS setup utility, press F2 when the Lenovo logo appears on the screen  
while the computer is starting up.  
Enabling 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.  
Check the GPU indicator: if the indicator is off, slide and release the GPU  
switch to enable Optimus.  
When Optimus is enabled, switching between integrated and discrete GPUs  
is performed automatically without user intervention. However, you can  
customize settings through the NVIDIA control panel to make the desired  
GPU active to perform image-rendering tasks for certain programs. For  
details, search for Optimus in the help system of the NVIDIA control panel.  
Notes:  
Optimus is not supported by all operating systems. Currently, Optimus is supported by  
®

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.  
Notes:  
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.

Using Lenovo OneKey Rescue system (without Windows  
operating system)  
In the event that the operating system cannot be loaded, follow the steps  
below to access OneKey Rescue system.  
• Shut down your computer.  
• Press the key to launch OneKey Rescue system.  
Within the program, you can choose to restore your system partition to the  
original factory status, or to a previously generated backup.  
Note: The recovery process is irreversible. Make sure to back up any critical data before  
using the recovery feature.  
Creating a recovery disc(s)  
Your computer does not ship with a recovery disc. You can use Lenovo  
OneKey Recovery system to create a recovery disc(s), which can be used to  
start and restore your computer in case of a system failure.  
To create a recovery disc(s):  
• Insert a recordable disc into the optical drive on your computer.  
Note: If your computer does not come with an integrated optical drive or if the integrated  
optical drive does not support disc creating, connect an appropriate external optical  
drive to your computer.  
• In Windows, press the OneKey Rescue system button to launch Lenovo  
OneKey Recovery system.  
• On the main screen, click Create Recovery Disc.  
• Choose the type of recovery disc(s). You can create three types of recovery  
disc(s): recovery disc(s) with existing backup image, recovery disc(s) from  
the current system partition, and factory default recovery disc(s). Select the  
type of recovery disc you want to create and follow the on-screen  
instructions.  
• Insert additional recordable disc(s) when prompted.

Notes:  
The estimated number of discs needed will be displayed before the process of creating the  
recovery disc(s) begins. To minimize the number of discs needed, use recordable DVDs as  
the media. Also make sure your optical drive is compatible with the disc intended for use.  
After recovery disc creation, number the discs appropriately for use in their correct  
order. The first disc created will be used to start the computer in the case of a system  
failure.

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.  
Notes:  
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 software 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.  
To install a DDR3 SDRAM, do the following:  
1
Touch a metal table or a grounded metal object to reduce any static  
electricity in your body, which could damage the DDR3 SDRAM. Do not  
touch the contact edge of the DDR3 SDRAM.
