Introduction

Use this guide to replace the trackpad assembly in your Retina MacBook 2017. This assembly includes the trackpad and the Haptic Engine.

  1. Before starting this procedure, you must disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide or follow the abbreviated instructions below to disable Auto Boot. Power on your Mac and launch Terminal. Copy and paste the following command (or type it exactly) into Terminal:
    • Before starting this procedure, you must disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide or follow the abbreviated instructions below to disable Auto Boot.

    • Power on your Mac and launch Terminal.

    • Copy and paste the following command (or type it exactly) into Terminal:

    • sudo nvram AutoBoot=%00

    • Press [return]. If prompted, enter your administrator password and press [return] again. Note: Your return key may also be labeled ⏎ or "enter."

    • You can now safely power down your Mac and open the bottom case, without it accidentally powering on.

    • When your repair is complete and your Mac is successfully reassembled, re-enable Auto Boot with the following command:

    • sudo nvram AutoBoot=%03

    Is this step necessary? I can’t perform this step as I am attempting to repair water damage and need to remove logic board & most likely replace the battery.

    @mac_medic You definitely don’t want the power coming on while the board is wet. In your case, I think powering on the machine to disable Auto Boot would do more damage than it prevents. I agree, skip this step and be prepared to disconnect the battery quickly if the laptop automatically powers on. Good luck!

    • Before proceeding, unplug and power down your MacBook. Close the display and lay it on a soft surface, top-side down.

    • Remove the following eight screws securing the lower case:

    • Two 1.8 mm P5 Pentalobe screws

    • Four 2.9 mm P5 Pentalobe screws

    • Two 6.1 mm P5 Pentalobe screws

    • Note the orientation of the screws as you remove them—they need to be reinstalled at a slight angle.

    • Throughout this repair, keep track of each screw and make sure it goes back exactly where it came from to avoid damaging your device.

    IMPORTANT. You’re not removing the bottom, yet. This step is solely to separate the panel from its clips, permitting inside access.

  2. Wedge your fingers between the upper case and the lower case, starting from the rear of the MacBook between the hinges. Lift the lower case only slightly to avoid damaging the cables that connect the lower case to the upper case. Keeping a firm grip, lift steadily until the lower case separates slightly from the upper case.

    • Keeping a firm grip, lift steadily until the lower case separates slightly from the upper case.

    • You may experience a lot of resistance when lifting the lower case. If necessary, slide an opening pick or other ESD-safe pry tool down the side edges of the lower case to pop the two hidden retaining clips free.

    • During reassembly, to re-engage the clips, press firmly near both side edges of the lower case (near where the pick is inserted in the third image) until you hear the clips snap into place.

  3. While holding the lower case in place, carefully flip the MacBook over so the Apple logo faces up.

  4. Lift the upper case and display together from the front edge and raise it to about a 45˚ angle. It may be helpful to prop the MacBook open in this position for the next step.

  5. Use the flat end of a spudger to press and hold the small gold 'battery disconnect' button. If the power LED is lit up, continue holding the button until the LED goes dark, and then release. This may take up to 10 seconds. If the LED does not light, release the button after 5-10 seconds. Press and hold it again for 5-10 seconds, and release. Finally, press and hold it a third time for 5-10 seconds, and release.

    cannot turn on the led after replacing the new screen, even after following the turn on instructions upper…

    on reassembly, I had to plug my laptop in to reactivate the LED light

    Does anyone know how to turn it back on..? I plugged the laptop in and saw the LED Light, but it won’t turn on

    mmcsorley - Réponse

    After reassembly I could not restart my MacBook using the power button or after SMC reset (shift-ctrl-option-pwr). I had to connect my MacBook to its charging cable to get the battery LED to re-illuminate. After that it was all normal.

  11. Carefully close the MacBook and flip it over once again, so that the Apple logo faces up. Lifting from the front edge, raise the upper case/display assembly to about a 90° angle, and prop it up against something sturdy so you don't have to hold it. Add a piece of tape near the track pad to secure the upper case and prevent accidental movement.

    • It's possible to open the MacBook all the way and lay both sides down flat, but this may damage the flex cables and is not recommended.

  12. Remove the single 2.9 mm T5 Torx screw securing the battery connector to the logic board.

    From my experience it’s important to carefully press and hold the small button above left of the Battery Discharge label. Use a plastic spudger or finger tip. The illuminated yellow LED to the right will go off. I believe this discharges remaining electricity from logic board protecting it during repair.

    * I cannot find any documentation to support this, but I have damaged boards by not including this step.

    What is with the all plastic end of this cable that appears to just be glued right on top of its connector?

    Does the new one just stick back right on top?

    (In this photo it is the bottom side of the cable below the white water indicator sticker)

    • As an added precaution, you may physically disconnect the battery by inserting a battery isolation pick between the logic board and the battery connector.

    What happen if you don’t disconnect the battery? I didn’t and I saw smoke coming out when I connected the pad flex cable and the computer still started up

    DSANTIAGOSOY - Réponse

    If you don’t disconnect the battery you might accidentally short something on the logic board since power is still running through everything while you’re working on it. You can complete the repair without disconnecting the battery, but you risk accidentally breaking your logic board. It’s much safer to keep the battery disconnected while you’re working.

    This may require a T4 for the MacBook Retina early 2015. A T3 was too small, but this machine already had a replacement keyboard and body due to Apple recall. Just be aware.

Why do you need to disconnect the audio jack and USB-C port?
