Reserve Battery
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.
