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:
zCharging will not start if the battery’s temperature is below 0 °C (32 °F) or above 40 °C (104 °F); the charging process will stop if the battery’s temperature 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.
zDuring 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.
