Chapter 2. Using Your Computer

Checking Battery Status

You can determine the percentage of battery power remaining by using Windows Power options.

The amount of battery power you use determines how long you can use your computer between charges. As computer users’ habits and needs will vary, 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 from the time you start using your computer.

The way you use your computer: for example, how often you access the hard disk drive and how bright you make the computer display.

Using the AC Adapter

The power to run your computer can come either from the lithium-ion (Li- ion) battery pack provided with it, or from AC power through the AC adapter. While you use AC power, the battery charges automatically.

The AC adapter that comes with your computer has two basic components:

1 The transformer pack that converts AC power for use with the computer.

2 The power cord that plugs into the AC outlet the transformer pack.
