Caution
This procedure requires System Configuration. After you’ve completed all removal and reassembly steps, learn how to initiate the System Configuration process.
If you replace the logic board, you’ll need a separate Mac running the latest version of macOS or a separate Mac with Apple Configurator installed to restore the Mac before initiating the System Configuration process.
Removal
Place the computer with the front ports facing you.
Insert the Torx T5 bit into the 10–34 Ncm adjustable torque driver. Set the torque value to 11.5 Ncm.
Use the adjustable torque driver and Torx T5 bit to remove the two T5 screws (923-07101) from antenna 1.
Lift antenna 1 from the housing (1). Then secure antenna 1 to the logic board with a piece of Kapton tape (2).
- Caution: Don’t damage the parts on the logic board.
Rotate the computer to access the other side as shown. Use the antenna tool to lift the ends of two of the three antenna coaxial cables off the connectors on the logic board.
Keep the Torx T5 bit in the 10–34 Ncm adjustable torque driver. Set the torque value to 11.5 Ncm.
Use the adjustable torque driver and the Torx T5 bit to remove the two T5 screws (923-07101) from antenna 2.
Lift antenna 2 out of the housing. Save antenna 2 for reassembly.
Rotate the computer as shown to access antenna 3.
Lift the antenna coaxial cable out of the antenna coaxial cable grounding clips in the housing.
Use Kapton tape to secure the antenna coaxial cable to the housing.
Apply Kapton tape inside the housing near the four logic board screws to avoid damaging the housing.
Insert the 10IP bit into the 1.2–3 Nm adjustable torque driver.
Use the adjustable torque driver and 10IP bit to remove the four 10IP screws (923-07094) from the logic board.
Tilt up the logic board as shown.
Note: The fan is attached to the logic board and can be used to help tilt up the logic board.
Continue to tilt up the logic board. Slide it slightly toward the front of the housing until you see a gap between the back of the housing and the logic board (1). Ensure that the antenna coaxial cable (2) and fan flex cables (3) are free of the housing.
Hold the logic board by the edges until the fan is above the edge of the housing. Then support the logic board from under the fan and lift the logic board and fan out of the housing.
If you’re removing the logic board as part of another procedure, skip to reassembly step 8. If you’re replacing the existing logic board, continue to step 19.
Lift the end of the power supply signal cable off the connector on the logic board. Then remove the power supply signal cable from the logic board and save it for reassembly.
Insert the 10IP bit into the 0.3–1.2 Nm adjustable torque driver. Set the torque value to 0.7 Nm.
Use the 0.3–1.2 Nm adjustable torque driver and 10IP bit to remove the two 10IP screws (923-07098) from the bus bar.
Remove the bus bar and save it for reassembly.
Use the 10–34 Ncm adjustable torque driver and 8IP bit to remove the 8IP speaker standoff screw (923-07108) from the logic board.
Remove the SSD modules, fan, and antenna 1 from the logic board and save them for reassembly.
Reassembly
Important: If you’re installing a replacement logic board, complete all reassembly steps. If you’re reinstalling the existing logic board, skip to reassembly step 8.
Reinstall antenna 1, fan, and SSD modules onto the replacement logic board.
Set the torque value of the 10–34 Ncm adjustable torque driver to 16 Ncm. Then use the 10–34 Ncm adjustable torque driver and 8IP bit (923-07595) to reinstall the 8IP speaker standoff screw (923-07108) into the replacement logic board.
Remove the pull tab (1) from under the battery on the replacement logic board.
- Caution: Failure to remove the pull tab from under the battery will affect the functionality of the computer.
Use the T5 screwdriver to remove the two T5 screws (923-07617) (2) from the battery cover on the replacement logic board. Save the battery, battery cover, and two T5 screws for battery reassembly.
Position the bus bar on the replacement logic board. Align the bottom screw holes on the bus bar (1) with the screw holes on the logic board (2).
Set the torque value of the 0.3–1.2 Nm adjustable torque driver to 0.7 Nm. Then use the 0.3–1.2 Nm adjustable torque driver and 10IP bit to reinstall the two 10IP screws (923-07098) into the bus bar (2) and replacement logic board.
Press the end of the power supply signal cable into the connector on the replacement logic board (3).
Ensure that Kapton tape is applied inside the housing near the four screw mounts for the logic board.
Rotate the housing as shown. Then tilt down the thermal module end of the logic board into the housing as shown.
Continue to tilt down the logic board (1) and slide it toward the back of the housing (2). After the fan is below the edge of the housing, slide the logic board fully toward the back of the housing.
Insert the 10IP bit into the 1.2–3 Nm adjustable torque driver. Set the torque value to 2.7 Nm.
Use the adjustable torque driver and the 10IP bit to partially reinstall the four 10IP screws (923-07094) into the logic board. Then fully reinstall the four 10IP screws.
Remove the Kapton tape from the housing and the antenna coaxial cable.
Rotate the computer so the front ports are facing you.
Remove the Kapton tape securing antenna 1 to the logic board (1). Then position antenna 1 in the housing (2).
Insert the Torx T5 bit into the 10–34 Ncm adjustable torque driver. Set the torque driver to 11.5 Ncm.
Use the adjustable torque driver and the Torx T5 bit to reinstall the two T5 screws (923-07101) into antenna 1.
Use the black stick to press the antenna coaxial cable into the antenna coaxial cable grounding clips in the housing.
Rotate the computer so the front ports are facing you. Position antenna 2 in the housing.
Insert the Torx T5 bit into the 10–34 Ncm adjustable torque driver. Set the torque driver to 11.5 Ncm.
Use the adjustable torque driver and Torx T5 bit to reinstall the two T5 screws (923-07101) into antenna 2.
Use ESD-safe tweezers to position the ends of the two antenna coaxial cables over the connectors.
Use the blunt end of the antenna tool to press the ends of the antenna coaxial cables to the connectors in the order shown.
Reinstall the following parts to complete reassembly:
Caution
After you’ve completed all removal and reassembly steps, learn how to initiate the System Configuration process.
If you replaced the logic board, the computer won’t start up and the status indicator light will flash amber. Follow the instructions to restore the Mac. Then initiate the System Configuration process.
