using the AC adapter.
NOTE: Care and maintenance information for the battery is

Charging the Battery Pack
NOTE:
 Charging 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 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.
 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.
It takes approximately 3.5~4.5 hours to fully charge the battery when the computer
is off and 4~6 hours when the computer is on and in an idle state.
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.
