Checking battery status
You can determine the percentage of battery power remaining by checking
the battery icon in the notification area.
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: 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.
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.

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 pre-installed
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.
For more instructions, see the Help file of Lenovo OneKey Recovery.
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.
26
Chapter 4. OneKey Rescue system
Using Lenovo OneKey Rescue system (without Windows
operating system)
In the event that the operating system cannot be loaded, follow the steps
below to start OneKey Rescue system.
• Shut down your computer.
• Press the OneKey Rescue system button to start 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.
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.
• In Windows, press the OneKey Rescue system button to launch Lenovo
OneKey Recovery system.
Note:
•The recovery process is irreversible. Make sure to back up any critical data before using
the recovery feature.
•You can use the tip of an unfolded paper clip (or similar object without a sharp tip) to
gently press the OneKey Rescue system button.
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.
27
Chapter 4. OneKey Rescue 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.
Note:
•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.
