Figure 18. Reserve Battery Removal

NOTICE: The reserve battery provides power to the computer's RTC

and nonvolatile random-access memory (NVRAM) when the com-

puter is turned off. Removing the battery causes the computer to lose

the date and time information as well as all user-specified parame-

ters in the BIOS. If possible, make a copy of this information before

you remove the reserve battery.

1. Remove the keyboard bezel.

2. Remove the keyboard assembly.

3. Peel the reserve battery away from the foam pad on the system board

(see Figure 18).

The reserve battery is located between the memory module and the PC

Card bay, and it is attached to the system board with an adhesive foam

pad.

4. Disconnect the reserve battery cable from the connector on the system

board.

5. Remove the remnants of the foam pad from the system board.
