Mac mini Model A1176 Audio Board Replacement

Step 1 Internal Frame




• Later in this guide you will remove several recessed Phillips screws. Bit drivers are generally too large to fit in the recesses, so be sure to have a thin shafted Phillips screwdriver on hand.
• First remove the AirPort antenna (the larger of the two), located near the power button.
• Slightly squeeze the two retaining arms toward each other and lift the AirPort antenna off its post.
• Squeezing the two posts excessively will surely break them off the internal frame. Work delicately.
• During reinstallation, you will have to slightly squeeze the two posts together so they fit into the openings on the AirPort antenna board.
Step 2



• Use the tip of a spudger to slightly lift the left side of the ZIF cable lock up from its socket.
• The ZIF cable lock will lift about 1 mm and stop. Do not try to completely remove the ZIF cable lock.
Step 3
• Lift the audio board ribbon cable up out of its socket.
• If it refuses to lift from its socket, the ZIF cable lock is not fully released. Make sure it is evenly lifted about 1 mm from the socket on the interconnect board.
Step 4
• Rotate the mini so that the SuperDrive slot loading mechanism is facing you.
• Use a pair of tweezers to lift the hard drive thermal sensor cable connector up off its socket on the logic board.
• Use tweezers to grab the connector (as seen in the picture), not the wires.
• The connector is located under the optical drive opening, next to the PRAM battery.
Step 5
• In the next few steps, you will remove the four Phillips screws securing the internal frame to the bottom case. Included in each step is an overview picture showing the general location and a closeup showing the actual screw.
• Remove the recessed Phillips screw near the power button securing the internal frame to the bottom housing.
Step 6
• Remove the recessed Phillips screw near the sleep light securing the internal frame to the bottom housing.
• This screw is the longest of the four screws securing the internal frame to the bottom case.
Step 7
• Remove the Phillips screw from the internal frame near the Bluetooth antenna.
Step 8
• Remove the Phillips screw near the audio ports securing the internal frame to the bottom case.
Step 9
• Gently lift the internal frame up from the bottom housing, minding the AirPort antenna and any other cables that may get caught.
• It may be necessary to pull up near the interconnect board to separate it from the logic board.
Step 10 Audio Board
• Remove the single Phillips screw securing the audio board to the bottom housing.
Step 11
• Use a spudger to depress the small metal finger (shown in red) while lifting the audio board with your thumb.
Step 12
• Lift the free end of the audio board slightly and pull it away from the port side of the bottom housing.
