To avoid damage to the system board while you pry the battery
loose, be sure to insert the plastic screwdriver between the battery and the
socket (not the system board).
Insert the new battery into the socket with the side labeled "+" facing
up and snap it into place.
Close the computer cover (see page 71), and plug your computer and
devices into their electrical outlets.
Access the system setup program (see page 79) and restore the settings
you recorded in step 1.
Properly dispose of the old battery (see page 102).
