Power management
When you need to use your computer away from electrical outlets, you depend on battery power to keep
your computer running. Different computer components consume power at different rates. The more you
use the power-intensive components, the faster you consume battery power.

Checking battery status
The Power Manager Battery Gauge in the task tray displays the percentage of battery power remaining.
The rate at which you use battery power will determine how long you can use the battery of your computer
between charges. Because each computer user has different habits and needs, it is difcult 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 (Li-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 that comes with your computer has two basic components:
• The transformer pack that converts ac power adapter for use with the computer.
• 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 your computer.
Connecting the ac power adapter
To use the ac power adapter, do the following. Be sure to take these steps in the order in which they are
given here.
1. Connect the ac power adapter to the power jack of the computer.
2. Connect the power cord to the transformer pack.
