    • Using the flat end of a spudger, gently pry the battery connector straight up out of its socket on the logic board.

    • Bend the battery cables back and out of the way, ensuring that the battery connector doesn't accidentally make contact with the logic board.

  5. MacBook Pro 15" Retina Display Mid 2012 I/O Board Replacement, AirPort/Camera Cable: step 5, image 1 of 1
    • Use a spudger or tweezers to pry the three AirPort antenna cables straight up off of their sockets on the AirPort board.

    • The cable connection points are fragile. Be careful to lift only on the connector, and not on the socket or cable.

    • To reconnect, align the connector carefully into position over the socket, and press it down firmly with the flat of your spudger.

    • Use the tip of a spudger to push the camera cable's plug toward the fan and out of its socket on the logic board.

    • The plug in the photo has six connections, but some models have twelve connections. The process of removing the plug from its socket is the same for both.

    • If the camera cable's plug won't come easily out of its socket on the logic board, fold back the rubber cover over the fan to gain access to the cable, then gently pull on the cable while using the spudger to gently push the plug out of its socket.

    • Be sure to push parallel to the board, first on one side, then the other, to slowly "walk" the plug out of its socket. Do not pry up, or you will damage the socket.

    • Using the flat end of a spudger, pry the I/O Board connector straight up out of its socket on the logic board.

    • During reassembly, connect this end first, as it does not flex.

    • Use the tip of a spudger to flip up the retaining flap on the right fan ribbon cable ZIF socket.

    • Be sure you are prying up on the hinged retaining flap, not the socket itself.

    • Starting at the top of the cable, slide a plastic opening tool under the right fan cable to free it from the logic board.

    • Use caution when freeing the cable, as it is strongly adhered to the logic board.
