    • Use the tip of a spudger to push the edges of the I/O board connector straight out of its socket on the logic board.

    • It is recommended to carefully push on both sides of the connector to "walk" it out of its socket.

    • Grab the black 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 straight out of its socket on the logic board.

    • Do not lift up on the display data cable, as its socket is very fragile. Pull the cable parallel to the face of the logic board.

    • Pry the headphone jack cable connector up off its socket on the logic board.

    • Grasp the plastic pull tab and pull the microphone ribbon cable out of its socket.

    • Repeat the previous procedure to disconnect the Trackpad ribbon cable from its socket on the logic board.

    I discovered that if the trackpad cable is damaged the keyboard will not work. I replaced the trackpad cable which had two damaged Ribbon pens. Once TP cable was replaced the keyboard also worked!

    • Carefully grasp the corner of the logic board (opposite of the I/O ports) and lift the logic board out of the upper case.

    When re-installing the Logic board, be careful not to trap any of ZIF cables under the board.

    You’ll need to tilt the board up from the end away from the DC-IN board in order to get the IO connectors inserted all the way. Be careful with the little fingers on top of the IO connectors.

    I had previously replaced the battery with the Newer Tech battery. The battery cable is not as flexible as the original battery, making the removal and insertion of the trackpad cable difficult.
