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:
 Charging will not start if the battery’s temperature is below 0 °C (32 °F) or above
45 °C (113 °F).
 The charging process will stop and the Battery Charge Indicator flashes red when
the battery’s temperature gets above 60 °C (140 °F). If this happens, the battery
pack may be damaged. Please contact your dealer.
 During charging, do not disconnect the AC adapter before the battery has been fully
charged; otherwise you will get a prematurely charged battery.
To charge the battery pack, connect the AC adapter to the computer and
an electrical outlet. The Battery Charge Indicator (
) on the
computer glows amber to indicate that charging is in progress. You are
advised to keep the computer power off while the battery is being
charged. When the battery is fully charged, the Battery Charge Indicator
is off.
