„ Checking battery status
You can determine the percentage of battery power remaining by using
Windows Power Options.
„ Charging the battery
When you find that the battery power is low, you need to charge the
battery or replace it with a fully charged one.
The battery is charged when the AC adapter is connected to the computer
and the battery is installed.
Charging time will depend on the usage environment.
You need to charge the battery in any of the following situations:
• When you purchase a new battery
• If the battery status indicator turns orange
• If the battery has not been used for a long time
Note: As 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:
• The amount of energy stored in the battery when you commence work.
• The way you use your computer: for example, how often you access the
hard disk drive and how bright you make the computer display.
