Removal

  1. Remove the rubber cover from the Touch ID board flexible cowling and save it for reassembly.

  2. Use the T3 screwdriver to remove the four outer corner T3 screws (923-06955) (1) and the two middle T3 screws (923-06942) (2) from the Touch ID board flexible cowling.

  3. Use ESD-safe tweezers to remove the Touch ID board flexible cowling from the top case. Save the cowling for reassembly.

  4. Use ESD-safe tweezers to peel the Touch ID board flex cable from the top case.

  5. Open the display to a 90-degree angle. Then place the computer on the table with the keyboard upright as shown.

  6. Support the Touch ID board as you route the Touch ID flex cable through the slot in the top case. Remove the Touch ID board from the keyboard side of the top case.

    • Important

      • If the Touch ID board wasn’t clicking properly before removal or the Touch ID shim falls out when you remove the Touch ID board, continue to removal step 7 to replace the Touch ID shim.

      • Ensure that your work surface is clean. Under the Touch ID board is the Touch ID shim, which is a small circular part. If it falls, you can more easily find it on a clean surface.

      • If you’re using the existing Touch ID shim, skip to reassembly step 1.

  7. Place the computer right side up. Spread the tips of the ESD-safe tweezers and use one tip to remove the shim from the circular recess under the Touch ID board.

    • Note: The shim has a small amount of adhesive and may stick to the top case.

Reassembly

  1. Place the computer right side up with the display still open.

    • Caution: Ensure that you place the computer on a clean surface to avoid damaging internal parts.

  2. Set two Y-shaped alignment tools in the Touch ID opening in the top case as shown. Secure the Y-shaped tools in the corner edges with Kapton tape.

    • Important: Ensure that the Touch ID shim is aligned in the recessed circle in the top case. If you are replacing the Touch ID shim, follow reassembly steps 3 through 5. If you’re using the existing shim, skip to reassembly step 6.

  3. Use ESD-safe tweezers to remove the medium Touch ID shim from the shim kit.

    • Note: The shim is black on the adhesive side and silver on the opposite side.

  4. Align the Touch ID shim in the recessed circle in the top case with the adhesive side down.

  5. Gently press the Touch ID shim to adhere it to the top case.

  6. Open the display to a 90-degree angle. Then place the computer on the table display-side down.

  7. Route the Touch ID board flex cable through the slot in the top case. Then position the Touch ID board in the opening in the top case.

  8. Ensure that the Touch ID button is held in place by the Y-shaped tools as you close the display.

    • Note: If you’re installing a replacement Touch ID board, remove the protective film from the glass surface.

  9. Place the computer display-side down. Then position the Touch ID board flexible cowling as shown.

  10. Use the T3 screwdriver to fully reinstall the four outer T3 screws (923-06955) (1). Then partially reinstall the two middle T3 screws (923-06942) (2).

  11. Place the computer right side up and remove the Y-shaped alignment tools.

  12. Close the display and place the computer display-side down.

  13. Use the T3 screwdriver to fully reinstall the two middle T3 screws.

  14. Press the Touch ID board flex cable to adhere it to the top case.

  15. Turn the top case right side up.

  16. Remove the Kapton tape and Y-shaped alignment tools. Then ensure that the Touch ID button still clicks when pressed.

    • Important

      • If the Touch ID button feels too loose or doesn’t click, repeat removal steps 2 through 6. Then repeat reassembly steps 1 through 16 with a larger Touch ID shim.

      • If the Touch ID button feels too stiff or doesn’t move, repeat removal steps 2 through 6. Then repeat reassembly steps 1 through 16 with a smaller Touch ID shim.

  17. Look directly over the Touch ID button. The spaces on each side should appear equal, and the Touch ID button should align with the function keys. If the gaps around the sides are unequal, repeat reassembly steps 2 through 16.

  18. Close the display and place the computer display-side down.

  19. Reinstall the rubber cover over the Touch ID board flexible cowling.
