Replacing the Internal Backup Battery
Your Power Mac G5 has an internal backup battery that preserves settings, such as the
date and time, when the computer is off. If you notice intermittent problems when
your Power Mac G5 starts up or changes in the date and time settings, you may need
to replace the battery. Your Power Mac G5 uses a CR 2032 Lithium coin cell battery.
Because batteries contain chemicals, which may be harmful to the
environment, please dispose of them according to your local environmental laws.
To replace the battery:
Open your computer and remove the side panel and air deflector following the
directions that begin on page 46.
Remove the old battery from the holder. If a memory module is installed in the DIMM
slot next to the battery, you may have to remove it before you remove the battery.
Installing the battery incorrectly may cause an explosion. Use only the same
type of battery or an equivalent recommended by the manufacturer of the original.
Insert the new battery in the holder with the negative side (–) facing up.
Replace the air deflector and side panel, following the directions on page 55.
Working Inside Your Computer
The battery is retained by the
