    • Apple sticks a small strip of clear plastic with adhesive applied to one side to the logic board behind the camera cable connector to keep it in its socket. When moving it out of the way, be sure not to break any surface-mount components off the logic board.

    • Hold the end of the cable retainer down with one finger while you use the tip of a spudger to slightly lift the other end and rotate it away from the camera cable connector.

    Bear in mind that the “Camera Cable” is also the cable connecting the logic board to the Wifi Airport Card, at least on the Glossy model (not sure about the Anti-Glare model). The Wifi Airport Card is located under the display’s clutch cover, and requires removing the display in order to access it.

    • Disconnect the camera cable by pulling the male end straight away from its socket.

    • Using the flat end of a spudger, pry the subwoofer connector straight up off the logic board.

    Be very careful to not get under the connector base on the logic board. You can pull it off. It is only secured by weak surface mount solder.

    I second that sentiment. The connector base is slightly elevated off the logic board, and it is easy to get your tool under that instead of the male plug you're trying to disconnect. I pulled mine off, and for now the speakers are tinny.

    I can't plug the subwoofer cable back. It seems to be too big. I have no idea, what I can do? Any ideas?

    • Remove the single 7 mm Phillips screw securing the display data cable retainer to the upper case.

    • Grab the plastic pull tab secured to the display data cable lock and rotate it toward the DC-in side of the computer.

    • Pull the display data cable connector straight away from its socket.

    • Make sure to pull the connector parallel to the face of the logic board, not straight up from its socket.

    • Remove the following screws:

    • Eight 3.5 mm T6 Torx screws securing the logic board to the upper case.

    • Two T6 Torx screws securing the DC-In board to the upper case.

    • Do not remove the logic board yet! There are connectors attached to the underside of the logic board that must first be disconnected.

    • Carefully lift the logic board assembly from the left side and work it out of the upper case, minding the port side that may get caught during removal.

    • Do not entirely remove the logic board yet!

    • Ensure that the logic board is free from all connections to the upper case (except the battery connector) before proceeding.

    I,ve done everything up to this step but my logic board still seems to be connected (by glue i think) to the black plastic underneath and the black frame that can't be unscrewed. Any idea how to get past this?

    For step 24, the same thing happened to me as did to Josh. The heat pipe had bonded with the plastic film which protects the back of the keyboard. By using a spudger i was able to pry at the area where the two were attached. I don't think this is intentional, they just melt together.

    Matt -

    Same happened to me. Matt is right. I gained extra clearance by removing both RAM modules. Then used the spudger. Sounds cracky but it´s all fine.

    • Lift the logic board enough to gain clearance and use a spudger to pry the microphone up off the upper case.

    • Slide the logic board away from the port openings and lift the assembly out of the upper case.

    • Before reinstalling the logic board, it is easiest to press the microphone down into its housing in the left speaker to keep it in place.
