Remove the keyboard-backlight cable, keyboard cable, and macro-keys cable from the routing guides (the small plastic tabs) on the computer base.

Do not force the cables out of the system board without lifting up the latches that hold them down first. Forcing out cables could result in them snaping or tearing, rendering them unusable.

You do not need to remove the hard drive to remove the battery, but it is advisable that you do so if you are concerned about dropping the computer while removing the battery.
