CAUTION: After the computer has been fully recharged, do not immediately disconnect
and reconnect the AC adapter to charge it again. Doing so may damage the battery.
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. When
the message “
Press F2 for System Utilities” appears, press
the
F2 key to invoke the program.
3. Disconnect the AC adapter and leave the computer on until the
battery is fully discharged. The computer will shut down
automatically.
4. Connect the AC adapter to fully charge the battery pack.
