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.
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 orange and green. 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.

Replacing the Battery
NOTICE:
You should not remove devices while your computer is in hibernate mode.
NOTE:
Some ExpressCards may not operate correctly after the computer exits hibernate mode. You may need to remove and reinsert the card (see
Removing an ExpressCard or Blank
), or simply restart (reboot) your computer.
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.
