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.
The battery is too hot to start charging if the
light flashes alternately green
and orange. 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.
