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.  
Removing the battery pack  
If you are not going to use the computer for an extended period of time, or if 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.  
• Do not short-circuit the battery pack.  
• Keep the battery pack away from children.  
• Do not put the battery pack in trash that is disposed of in landfills. When disposing of the  
battery, comply with local ordinances or regulations and your company’s safety standards.

Connecting USB devices  
You can connect a USB device to your computer by inserting its USB plug (Type A) into the USB  
port on your computer.  
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.  
Note: If your USB device uses a power cord, connect the device to a power source before connecting it.  
Otherwise, the device may not be recognized.

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  
mode after three seconds.  
is highlighted. The computer will switch to super silent  
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.  
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  
is highlighted. Dust cleaning will start after three seconds.  
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.

Securing your computer --------------------------------------------------------------------------------------------  
This section provides information about how to help protect your computer from theft and  
unauthorized use.  
Attaching a security lock (not supplied)  
You can attach a security lock to your computer to help prevent it from being removed without  
your permission. For details on installing the security lock, please refer to the instructions

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

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.  
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.

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.  
Y471A  
• 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 permanent 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 computer off. Never remove the drive while the system is  
operating, in sleep mode, or in hibernation mode.
