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 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.

Replacing the Battery

For information about replacing the optional second battery in the media bay, if applicable, see Media Bay.

To remove the battery:



1. If the computer is connected to a docking device (docked), undock it. See the documentation that came with your docking device for instructions.



2. Ensure that the computer is turned off or in hibernate mode (see Hibernate Mode).



3. Turn the computer upside down, with the front of the computer facing away from you.



4. Slide the battery-bay latch release on the right side of the battery until it engages and locks.



5. Slide and hold the battery-bay latch release on the left side of the battery, grasp the battery by the battery tab, and slide the battery horizontally

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.

CAUTION: Before performing these procedures, turn off the computer, disconnect the AC adapter from the electrical outlet and the computer,

disconnect the modem from the wall connector and computer, and remove any other external cables from the computer.

CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the battery only with a compatible battery purchased
