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 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.
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.
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,
click the icon on the taskbar. (Click the icon if the computer
is using AC power.)
Replacing the Battery Pack
CAUTION:
l There is danger of explosion if the battery is incorrectly replaced. Replace the
battery only with the computer manufacturer’s optional battery packs. Discard
used batteries according to the dealer’s instructions.
l Do not attempt to disassemble the battery pack.
