Turn off the laptop before proceeding.

Unscrew the 15 screws on the bottom panel using a Phillips #00 screwdriver.

Pry open the back cover with a plastic prying tool.

Unplug the battery cable from the motherboard to prevent a ground fault. Either use your hand or a pair of tweezers to unplug the battery cable.

Too much pressure from the spudger can break the clips that secure the back panel, but some flex is not dangerous.
