CMOS Battery Removal

Remove the 3-volt lithium battery from the system board as follows.
1. Turn off and unplug the system unit and any external options connected to
the system.
Removing the battery from the system board causes the
computer to lose system configuration information. If
possible, run Setup and record the system configuration
settings before removing the battery. Use that information to
restore the system after replacing the battery.
2. Remove the left side cover (see "Removing the Left Side Cover" earlier in
this section).
3. Locate the battery on the system board.
