Managing Power 3-4
NOTE: The battery level may automatically lessen due to the self-discharge process
(0.21 % per day), even when the battery pack is fully charged (100 %). This happens no
matter if the battery pack is installed in the computer.
Initializing the Battery Pack
You need to initialize a new battery pack before using it for the first time
or when the actual operating time of a battery pack is much less than
expected.
Initializing is the process of fully charging, discharging, and then
charging. It can take several hours.
1. Make sure that the computer power is turned off. Connect the AC
adapter to fully charge the battery pack.
2. After the battery pack is fully charged, turn on the computer. Press
the Enter key or click the left touchpad button when the prompt
appears on the screen during system startup. The prompt shows up on
the screen for only a few seconds. You must press the Enter key or
click the left touchpad button quickly.
3. A small window appears, select Launch System Setup to invoke the
program.
4. Disconnect the AC adapter and leave the computer on until the
battery is fully discharged. The computer will shut down
automatically.
5. Connect the AC adapter to fully charge the battery pack.
Checking the Battery Level
NOTE: Any battery level indication is an estimated result. The actual operating time can
be different from the estimated time, depending on how you are using the computer.
You can check the approximate battery level using the battery meter
function of the operating system. To read the battery level in Windows
Vista, click the icon on the system tray. To read the battery level in
Windows XP, click the icon on the taskbar. (Click the icon if the
computer is using AC power.)
