Installing Mac mini Model A1347 IR Sensor

Step 1 - Bottom Cover

Place your thumbs in the depressions cut into the bottom cover.

Rotate the bottom cover counter-clockwise until the white dot painted on the bottom cover is aligned with the ring inscribed on the outer case.

Step 2

Tilt the mini enough to allow the bottom cover to fall away from the outer case.

Remove the bottom cover and set it aside.

Step 3 - Fan

Remove the two 11.3 mm T6 Torx screws securing the fan to the logic board near the antenna plate.

Step 4

Lift the ear of the fan nearest the RAM up off the standoff secured to the outer case.

Step 5

Lift the fan out of the mini for enough clearance to access its connector.

Carefully pull the fan cables upward to lift the fan connector up out of its socket on the logic board.

Remove the fan.

Step 6 - Cowling

Remove the single 3.5 mm T6 Torx screw securing the cowling to the heat sink.

Step 7

Lift the cowling from the end nearest the antenna plate.

Rotate the cowling away from the outer case and remove it from the mini.

Step 8 - Antenna Plate

Remove the following screws securing the antenna plate to the mini:

Two 6.6 mm T8 Torx screws

Two 5.0 mm T8 Torx or 2.0 mm Hex screws (either will work)

Step 9

Slightly lift the antenna plate from the end closest to the RAM.

Carefully pull the antenna plate straight away from the circular rim of the outer case.

Do not remove the antenna plate yet. It is still attached to the AirPort/ Bluetooth board.

Step 10

Use the tip of a spudger to carefully pry the antenna connector up off the AirPort/Bluetooth board.

Step 11

Remove the antenna plate from the mini.

Step 12 - Logic Board

Remove the following three screws:

One 5.0 mm T8 Torx or 2.0 mm Hex screw (either will work)

One 16.2 mm T6 Torx screw

One 26 mm T6 Torx standoff

Step 13

Carefully pull the wires for both hard drive thermal sensors upward to lift their connectors up and out of the sockets on the logic board.

Step 14

Use the flat end of a spudger to pry both the hard drive and optical drive connectors up out of their sockets on the logic board.

Step 15

To disconnect the optical drive thermal sensor, pinch its cables between your thumb and a spudger and pry the spudger upward to lift the connector up and out of its socket on the logic board.

Step 16

Use the tip of a spudger to lift the IR sensor connector up and out of its socket on the logic board.

Step 17

To remove the logic board, two cylindrical rods must be inserted into the holes highlighted in red. Inserting instruments into any logic board holes other than the ones highlighted in red may destroy the logic board.

Insert two tools having a maximum diameter of 2.5 mm into the holes highlighted in red. Be sure they make contact with the outer case below the logic board before proceeding.

Carefully pry the tools toward the I/O board. The logic board & I/O board assembly should slightly slide out of the outer case.

Cease prying when the I/O board is visibly separated from the outer case. Remove the two tools.

Step 18

Simultaneously push the two plastic clips on the far left and right sides of the I/O board toward the middle of the I/O board and pull the I/O board away from the outer case.

Step 19

Pull the I/O board/logic board assembly out of the outer case enough to access the power connector.

Use a pair of tweezers to disconnect the power cable from the logic board.

Pull the power cable connector toward the optical drive opening.

Step 20

Carefully slide the logic board assembly out of the mini, minding any cables that may get caught.

Step 21 - Power Supply

Remove the 7.9 mm T6 Torx screw securing the power supply and optical drive to the outer case.

Step 22

Pull the AC-In socket retainer away from the side of the outer case and remove it from the mini.

Step 23

Rotate the AC-In connector 90 degrees counterclockwise.

Step 24

Slide the power supply out of the mini, minding any cables that may get caught.

Step 25 - Optical Drive

Remove the hard drive from the mini, minding any cables that may get caught.

Step 26

Remove the 7.9 mm T6 Torx screw securing the optical drive to the outer case.

Step 27

Slide the optical drive out of the outer case, minding any cables that may get caught.

Step 28 - IR Sensor

Carefully de-route the IR sensor cables from the channel in the optical drive bracket.

Step 29

Remove the 5 mm Phillips screw securing the IR board to the optical drive bracket.

Step 30

Remove the IR sensor from the optical drive bracket.

Be careful when removing the IR board from the optical drive bracket, as the lower plastic positioning pin has the tendency to get caught on the delicate IR board.

To reassemble your device, follow these instructions in reverse order.
