The battery is a 3.0-V, CR2032 coin-cell battery. To remove the battery, follow
these steps:
1. If possible, enter the system setup program (see Appendix A, “System
Setup Program,” for instructions) and print the system setup screens.
2. Remove the computer cover.
3. Remove the battery by prying it out of its socket with your fingers or a
blunt, nonconductive object, such as a plastic screwdriver.
To replace the battery, install the new battery with the “+” side facing up. Then
start the system setup program, and reset the System Date and System Time
categories. Compare the system configuration settings with the copy made in
step 1. Restore any system configuration information that was lost while replac-
ing the battery.
WARNING: There is a danger of the new battery exploding if it is
incorrectly installed. Replace the battery only with the same or equiva-
lent type recommended by the manufacturer. Discard used batteries
according to the manufacturer’s instructions.
