Replace a broken AirPort/Bluetooth board to regain wireless connectivity.

  1. Orient the iMac face-side down on a table with the bottom edge facing yourself.
    • Orient the iMac face-side down on a table with the bottom edge facing yourself.

    • Remove the two Phillips screws securing the access door to the bottom grille of your iMac.

    • The screws are captive in the access door.

    • Before beginning the repair, unplug the computer and press and hold the power switch for 20-30 seconds, to discharge internal capacitors.

  2. Remove the access door.
    • Remove the access door.

    • Remove the three T8 Torx screws securing the front bezel to the rear case along the lower edge of the iMac.

    • Turn the computer over.

    • Use your thumbs to press both RAM arms in past the front bezel for enough clearance to lift it off the rear case.

    • While holding the RAM arms in with your thumbs, lift the lower edge of the front bezel enough to clear the rear case.

    • Re-orient your iMac so it sits upright on the stand.

    • Insert a plastic card up into the corner of the air vent slot near the top of the rear case.

    • Push the card toward the top of the iMac to release the front bezel latch.

    • Pull the front bezel away from the rear case.

    • Repeat this process for the other side of the front bezel.

    • It may be necessary to apply several layers of duct tape to the top of the access card to aid in releasing the latches.

    • If the bezel refuses to release, try pressing the lower edge back onto the rear case and repeat this opening process.

    • Alternatively, you can use a strong magnet by holding it to the front top left/right corner of the display. You will hear a snapping sound when the hatch is released.

    • Lay your iMac stand-side down on a table.

    • Lift the front bezel from its lower edge and rotate it away from the rest of your iMac, minding the RAM arms that may get caught.

    • Lay the front bezel above the rest of the iMac.

    • If necessary, remove the piece of kapton tape wrapped around the microphone and camera connectors.

    • Disconnect both the camera and microphone cables.

    • Peel the lower EMI shield off the lower edge of the iMac and off the two vertical 4" sections on either side of the iMac.

    • It is not necessary to peel the lower EMI shield off the display.

    • Tape the lower EMI shield up against the face of the display to keep it out of the way while you work.

    • Remove the single T10 Torx screw securing the right speaker to the rear case.

    • Lift the right speaker out of the rear case.

    • The cable between the speaker and its connector is short, so either hold the speaker or allow it to hang from the iMac for the next few steps.

    • Remove the two Phillips screws securing the AirPort/Bluetooth board to the logic board.

    • On some models, these may be T6 Torx screws.

    • Use your finger to lift the AirPort/Bluetooth board from its left edge, disconnecting it from the logic board.

    • Lift the board from its left edge only.

    • Use the flat end of a spudger to pry both antenna connectors up off the AirPort/Bluetooth board.
