Setup program. If the date and time are not correct in the
System Setup program, replace your battery.
You can operate your system without a battery; however,
without a battery, the system configuration information is
erased if the system is turned off or unplugged from AC
power. In this case, you must enter the System Setup pro-
gram and reset the configuration options.
WARNING: There is a danger of the new battery
exploding if it is incorrectly installed. Replace the
battery only with the same or equivalent type recom-
mended by the manufacturer. Discard used batteries
according to the manufacturer's instructions.
Use the following procedure to replace the system battery
with another CR2032 coin-cell battery:
1. If you have not already done so, make a copy of
your system configuration information in the Sys-
tem Setup program.
If the settings are lost while you are replacing the
battery, refer to your written or printed copy of the
system configuration information to restore the cor-
rect settings. See Chapter 2, "Using the System
Setup Program," for instructions.
2. Remove the computer cover as instructed in
"Removing the Computer Cover" in Chapter 5.
CAUTION: See "Protecting Against Electro-
static Discharge" in the safety instructions at
the front of this guide.
3. To access the battery on the system board,
remove the expansion-card cage as described in
"Removing the Expansion-Card Cage" in Chap-
ter 5.

4. Locate the battery and remove it.
CAUTION: If you pry the battery out of its
socket with a blunt object, be careful not to
touch the system board with the object. Make
certain that the object is inserted between the
battery and the socket before attempting to pry
out the battery. Otherwise, you may damage
the system board by prying off the socket or by
breaking circuit traces on the system board.
The battery is mounted in a socket labeled "BAT-
TERY" on the top left side of the system board as
you face the side of the system (see Figure 6-1).
Pry the battery out of its socket with your fingers or
with a blunt, nonconductive object, such as a plastic
screwdriver.
5. Install the new battery.
Orient the battery with the side labeled "+" facing up
(see Figure 6-14). Then insert the battery into the
socket, and snap it into place.
