Instructions
Place the plastic analog sticks back into the PlayStation 3's front casing. Locate the internal battery that is used to power the controller. Insert the internal battery into the PS3's printed circuit board.
Reinsert the printed circuit board into the front casing. Fasten the screw that holds the circuit board into the front casing of the PS3.
Push both parts of the casing together. Slide the casing with the face buttons on it in a downward motion. Simultaneously slide the bottom casing upward to lock the controller in place.
Reinstall the five screws into the bottom of the controller to secure the two casing sections together.
