Managing Power
The charging times are as follows:
Battery Type
Charging Time
Computer is Off Computer is On and
in Idle State
9-cell (4 A) 3.5~4.5 hours 4.0~6.0 hours
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 to Enter BIOS Setup” appears, press F2 to enter
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.
