Using the ac power adapter and the battery pack

This topic provides information about how to use the ac power adapter and the battery for your computer.

Checking the battery status

The battery gauge in the Windows notification area displays the percentage of battery power remaining.
The rate at which you use battery power will determine how long you can use the battery between charges.
Because 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:
• How much energy is stored in the battery when you begin to work.
• The way you use your computer: how often you access the hard disk drive, how bright you make the
computer display.

Using the ac power adapter

The power to run your computer can come either from the lithium-ion battery pack provided with it, or from
ac power through the ac power adapter. While you use ac power, the battery charges automatically.
The ac power adapter has two basic components:
1. The transformer pack that converts ac power adapter for use with the computer.
2. The power cord that plugs into the ac outlet and into the transformer pack.
Attention: Using an improper power cord could cause severe damage to the computer.
