CAUTION: A new battery can explode if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer's instructions.
To replace the battery:
Enter the system setup program and record the values for all the screens
(see Entering System Setup) so that you can restore the correct settings
after installing the new battery.
NOTICE: If you pry the battery out of its socket with a blunt object, be careful not to touch the system board with the object. Ensure that the object is inserted between the battery and the socket before you attempt 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.
Remove the battery by carefully prying it out of its socket with your fingers
or with a blunt, nonconducting object, such as a plastic screwdriver.
Insert the new battery into the socket with the side labeled "+" facing up,
and then snap the battery into place.
