Charging the Battery

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.

NOTE: With Dell™ ExpressCharge™, when the computer is turned off, the AC

adapter charges a completely discharged battery to 80 percent in about 1 hour and

to 100 percent in approximately 2 hours. Charge time is longer with the computer

turned on. You can leave the battery in the computer for as long as you like. The

battery’s internal circuitry prevents the battery from overcharging.

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.
