Charging the Battery

NOTE: With Dell™ ExpressCharge™, 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's internal
circuitry prevents the battery from overcharging.
NOTE: If you want to use a 9-cell battery to obtain Dell ExpressCharge, you need to use it in
conjunction with a 90-W AC adapter.
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.

not charge when you connect the computer to an electrical outlet.
