Charging the Battery
NOTE: The AC adapter charges a completely discharged battery in approximately 1 hour with
the computer turned off. Charge time is longer with the computer turned on. You can leave the
battery in the computer as long as you like. The battery internal circuitry prevents the battery
from overcharging.
.
When you connect the computer to an electrical outlet or install a battery while the
computer is connected to an electrical outlet, the computer checks the battery charge and
temperature. If necessary, the AC adapter then charges the battery and maintains the
battery charge.
If the battery is hot from being used in your computer or being in a hot environment, the
battery may not charge when you connect the computer to an electrical outlet.
The battery is too hot to start charging if the light flashes alternately green and orange.
Shut down the computer, disconnect the computer from the electrical outlet and allow the
computer and the battery to cool to room temperature. Then connect the computer to an
electrical outlet to continue charging the battery.
For more information on resolving problems with a battery, see page 50.

CAUTION: Before performing these procedures, turn off the computer,
disconnect it from the electrical outlet, and disconnect the modem from the
telephone wall jack.
NOTICE: If you choose to replace the battery with the computer in standby mode, you have up
to 90 seconds to complete the battery replacement before the computer shuts down and loses any
unsaved data.
