battery pack.

dialog box”. To open the dialog box:

Battery Pack
When not connected to an external power source, your computer operates with the
rechargeable battery pack. The duration of the battery life may be longer if the
computer’s power management is active. See the next section for power management.
To keep the battery life long:
•
Condition the battery pack if the actual remaining power in your battery is less than
what Windows
Power Meter indicates. (See Conditioning the Battery Pack section
in this chapter.)
•
Turn off your computer when you are not using it.
•
The duration of the battery depends on the computer usage. Using
applications, which heavily use external peripherals, will result in
shorter battery life.
•
When using the computer for several hours with battery packs, enable
power management and set
System hibernate . Refer to the Power
Management section in this chapter.
•
When the battery has not been charged, your computer may not operate
properly. Connect the AC power source to charge the battery.
