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 40 °C (104 °F).
z The charging process will stop when the battery’s temperature gets
above 60 °C (140 °F). The Battery Charge Indicator turns off in this state.
Once the battery’s temperature drops within the safe range, charging
will automatically resume with the Battery Charge Indicator glowing
amber.
z 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.
