Charging the Battery
To charge the battery, plug the AC adapter into the system and an
electrical outlet. The AC adapter converts alternating current (AC) into
direct current (DC). When the power switch is turned on, the AC adapter
supplies power to the system and recharges the battery pack only when the
system in suspend mode. Otherwise, to recharge you must turn off the
computer.
Recharging takes about 80 minutes for an empty battery pack when the
computer is off or in suspend mode. The battery will not recharge while
the computer is being used.
While the battery is charging, the CHARGE LED is orange. Once the
battery is fully charged, the CHARGE LED turns green.
Pre-charging a Dead Battery
If the battery has been completely discharged or placed in prolonged
storage, it may need a pre-charge in addition to a normal charge. A pre-
charge can take as little as a few seconds or as much as an hour in some
extreme cases. While the battery pre-charges, the CHARGE LED will
slowly flash orange.
