Replacing the Battery
All motherboards use a battery to maintain system configuration information. If it fails
to maintain system configuration, replace it with an identical rated battery from the
same manufacturer.
Caution
Removing the battery from the motherboard causes the com-
puter to lose system configuration information. Before removing
it, run Setup and record the system configuration settings.
Use this information to restore the server after replacing the
battery.
To replace the battery on the motherboard:
1. Turn off and unplug the server and any external options connected to the
server.
2. Remove the top cover. See “Removing and Replacing the Top Cover” on
page 175.
3. Locate the battery on the motherboard. See “Motherboard” on page 30.
4. Carefully remove the battery from the battery socket on the motherboard.
Warning
The battery may explode if it is incorrectly replaced or improp-
erly discarded.
Use only an identical rated battery from the same manufacturer.
