roubleshooting the Battery
WARNING
There is a danger of a new battery exploding if it is
incorrectly installed. Replace the battery only with
the same or equivalent type recommended by the
manufacturer. Discard used batteries according to
the manufacturer's instructions.
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.
CAUTION: See "Protecting Against Electro-
static Discharge" in the safety instructions at
the front of this guide.

connector on the system board?
Yes. Go to step 5.

battery cable to the system board.

problem.

See your system documentation for instructions.
