Battery Pack
The battery pack is the internal power source for the computer. It is
rechargeable using the AC adapter.
The operating time of a fully charged battery pack depends on how you
are using the computer. When your applications often access peripherals,
you will experience a shorter operating time.
NOTE: Care and maintenance information for the battery is
provided in the “Battery Pack Guidelines” section in Chapter 7.
Charging the Battery Pack
NOTE:
z Charging will not start if the battery’s temperature is below 0
°C (32 °F) or above
60 °C (140 °F).
z The charging process will stop and the Battery Charge
Indicator flashes green when the battery’s temperature gets
above 60 °C (140 °F). If this happens, the battery pack may
be damaged. Please contact your dealer.
z During charging, do not disconnect the AC adapter before
the battery has been fully charged; otherwise you will get a
prematurely charged battery.
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.
