and performance of each component in your computer. If your computer is

pre-installed with an operating system, Lenovo provides all drivers that

you need in your hard disk.

When you cannot use the AC adapter to power your computer, you may

depend on battery power to keep your computer running.

Note:

The operating system may run slower when using the battery mode.

 Checking battery status

You can determine the percentage of battery power remaining by using

Windows Power options.

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.
