5-24 Dell OptiPlex GXa and OptiPlex NX Systems Service Manual
To remove the system battery, follow these steps:
1. If possible, boot the system and enter the System Setup program. Then
record important system configuration information (see Appendix A,
“System Setup Program,” for details).
2. Turn off power to all peripherals, and disconnect the AC power cable
from its AC outlet.
3. Remove the computer cover.
4. Remove the expansion-card cage, and locate the battery in the front-
right corner of the system board adjacent to the DIMM connectors (see
Figure 5-18).
5. Remove the battery by carefully prying it out of its socket with your
fingers or with a blunt, nonconducting object, such as a plastic
screwdriver.
6. Insert the battery into the socket (with the positive side labeled “+”
facing upwards), and snap it into place.
7. Replace the expansion-card cage; replace the computer cover, re-
connect all cabling, and reboot the system.
8. Enter the System Setup program, and configure the system using the
information from the printouts you made earlier.
9. Turn off the computer; wait 10 or more minutes, and then reenter the
System Setup program to ensure that the date and time are still correct,
indicating that the system battery is functioning correctly.
CAUTION: If you pry out the battery with a blunt object, be careful not
to touch the system board with the object. Ensure 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 traces on the system board.
WARNING: There is a danger of the new battery exploding if it is in-
correctly installed. When you replace the system battery, orient the new
battery with the “+” facing up (see Figure 5-23). Replace the battery only
with the same or equivalent type recommended by the manufacturer.
Discard used batteries according to the manufacturer’s instructions.
