The battery is mounted in a socket labeled "BATTERY" located to the left of the top two PCI expansion-card
connectors (as you face the system board).(See Figure 1, System Board Features.)
CAUTION: If you pry the battery out of its socket with a blunt object, be careful not to touch the
system board with the object. Make certain that the object is inserted between the battery and the
socket before attempting to pry out the battery. Otherwise, you may damage the system board by
prying off the socket or by breaking circuit traces on the system board.
Pry the battery out of its socket with your fingers or with a blunt, nonconductive object, such as a plastic
screwdriver (see Figure 11, System Battery and Battery Socket).
