Remove the 9 screws from the back cover with the Phillips #0 screwdriver. NOTE* You do not need to remove the screws completely as you just need to loosen them enough to remove the cover.

Remove the 3 battery screws with a Phillips #0 screwdriver.
Temporarily disconnect the bottom left corner battery sticker. NOTE* You will need to reconnect this sticker when installing the new battery.
