T
roubleshooting the Battery
If an error message indicates a problem with the battery
or if the System Setup program loses the system configu-
ration information when the computer is turned off, the
battery may be defective.
Follow these steps to troubleshoot the battery:
1. Turn off the system, including any attached
peripherals, and disconnect all the AC power
cables from their power sources. Also, disconnect
any telephone or telecommunication lines from
the computer.
2. Remove the computer cover.
3. Check the connection of the battery to the system
board.
Some systems have a coin cell battery that snaps into
a socket on the system board. Other systems have a
battery with a cable that attaches to a header connec-
tor on the system board.
Is the battery firmly attached to the battery socket or
connector on the system board?
Yes. Go to step 5.
No. Go to step 4.
4. Reseat the battery in its socket, or reconnect the
battery cable to the system board.
Is the problem resolved?
Yes. The connection was loose. You have fixed the
problem.
No. Go to step 5.
5. Replace the battery.
See your system documentation for instructions.
Is the problem resolved?
Yes. The battery’s charge was low. You have fixed
the problem.
No. See Chapter 7, “Getting Help,” for instructions
on obtaining technical assistance.
