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.
