roubleshooting and Replacing
the Battery on the Control Panel
The battery on the control panel stores the power state of
the system. For example, if a power failure occurs while
the system is running, the system will remain on when
power is restored. However, if the system does not keep
its power state during a power interruption, you should
replace the battery. Follow these steps to replace the bat-
tery on the control panel:
1. Turn off the system, including any attached
peripherals, and disconnect all the AC power
cables from their power sources.
2. Remove the left and right computer covers.
See “Removing the Computer Covers” earlier in this
chapter.
3. Remove the front bezel.
See “Removing the Front Bezel” earlier in this
chapter.
4. Remove the battery.
The battery is located just above the center of the
control panel.
Pry the battery out of its socket with your fingers or a
blunt, nonconductive object, such as a plastic
screwdriver.
5. Install the new battery with the “+” side facing up
(see Figure 7-6).
