Chapter 2. Using your computer
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:
ƒ
The amount of energy stored in the battery from the time you start using
your computer.
ƒ
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 and the transformer pack.
Attention:
Using an improper power cord could cause severe damage to your computer.
To use the AC adapter, do the following. Be sure to take these steps in the
order in which they are given here.
1
Connect the AC adapter to the power jack of the computer.
