Replacing the Battery

All motherboards use a battery to maintain system configuration information. If it fails

to maintain system configuration, replace it with an identically rated battery from the

same manufacturer.

Replace the battery as described below:

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 system after replacing the

battery.

1.  Turn off and unplug the system unit and any external options connected to the

system.

2.  Remove the right side door. 

See “Removing the Right Side Door” on page 122.

3.  Locate the battery on the motherboard. 

See “Motherboard” on page 20.

4.  Use your finger to 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.
