Lift the right speaker out of its housing and set it to the side.

If you have a Santa Rosa/Penryn model, skip this step.

Using a spudger, gently pry up the white plastic slot and slide the metal c-channel to the right and away from the display.

Use a spudger to carefully disconnect the microphone cable from the logic board. You'll want to work from side to side, and slowly wiggle the connector out of its socket.

Pulling on this connector vertically will break the socket off the logic board. This connector should be removed horizontally by gently pulling the microphone cable toward the screen while working a spudger between the connector and the socket.

Lift up on the black right speaker cable with one hand, and deroute the microphone cable from the silver metal clip just above the right RAM slot.

This metal clip may not be present in all models. Be sure that the cable is free from any hold downs around this area before proceeding.

Remove the single 4.2 mm Phillips screw securing the ground loop in the right speaker cable and microphone cable to the metal framework.

Deroute the microphone cable and the black display data cable from the tabs at the bottom of the subwoofer.

Remove the single 3 mm Phillips screw securing the ground loop in the display data cable located just above the Bluetooth board.

Disconnect the three antenna cables from the Airport card. There may be a square foam piece over the logic board connector.

Disconnect the inverter cable from the socket by inserting the spudger between the right or left edge of the plug and the socket, and prying gently upward. (Do NOT pry the entire socket off the board... you must pull the plug from within the socket.) The inverter plug lifts vertically out of the socket. Do not pull it in the direction of the connecting wires or you will tear the socket off.

If you have a MacBook Core 2 Duo Santa Rosa/Penryn, there are only two antenna cables and the black inverter cable is in a different location.
