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 internal temperature of the battery pack is
below 0 °C (32 °F) or above 50 °C (122 °F); the charging process will stop
if the internal temperature of the battery pack gets above 60 °C (140
°F). To avoid damaging the battery under this situation, disconnect the
AC adapter and wait for the battery to return to room temperature
before charging again.
 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 lights green.
