Now that the three wires are exposed, follow the wires to the white base that is plugged into the motherboard.

Using the tech knife, carefully remove the glue that keeps the plug in place.

Using the tweezers, carefully disconnect the plug from the motherboard.

WARNING: Make sure the battery is drained of all power for safety reasons.

There should still be a small white base attached to the motherboard, where the plug will eventually be plugged back in.
