36 Using a Battery
Replacing the Battery
CAUTION: Using an incompatible battery may increase the risk of fire or explosion. Replace the battery only
with a compatible battery purchased from Dell. The battery is designed to work with your Dell™ computer. Do not
use a battery from other computers with your computer.
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.
NOTICE: You must remove all external cables from the computer to avoid possible connector damage.
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.
3
Slide the two latch releases on the bottom of the computer, and then remove the battery from the bay.
To replace the battery, follow the removal procedure in reverse order.
Storing a Battery
Remove the battery when you store your computer for an extended period of time. A battery discharges
during prolonged storage. After a long storage period, recharge the battery fully (see "Charging the
Battery" on page 35) before you use it.
