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.
4. Install the new battery.
