Power management
Use your computer with ac power whenever ac power is available. Use your computer with battery power
when ac power is not available.
Checking the battery status
The battery icon in the Windows notification area displays the percentage of battery power remaining.
Different computer components consume power at different rates. The more you use the power-intensive
components, the faster you consume battery power. 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
When you use ac power, the battery charges automatically.
