Introduction

Use this guide to replace the Touch ID sensor/power button in a Late 2020 MacBook Air (M1).

Note that Touch ID will not function after replacing the Touch ID sensor. The MacBook’s original Touch ID sensor is uniquely paired to the logic board at the factory—and without Apple’s proprietary calibration process, even a genuine replacement Touch ID sensor from another MacBook Air won’t work.

If you replace the Touch ID sensor, you must install a paired logic board to retain Touch ID functionality.

    • Before starting this procedure, you should 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 to disable Auto Boot.

    • If your MacBook is running Big Sur v11.1 or later, disabling Auto Boot may not work. You can proceed normally, but make sure to disconnect the battery as soon as you're inside.

    • Completely power off and unplug your MacBook before you start. Close the display and flip the entire laptop upside-down.

    • Use a P5 driver to remove the following screws:

    • Two 7.9 mm screws

    • Two 7.3 mm screws

    • Six 2.6 mm screws

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

    • Wedge your fingers between the display and the lower case and pull upward to pop off the lower case.

    • Remove the lower case.

    • To reinstall the lower case:

    • Set it in place and press firmly to engage the two hidden clips underneath. You should feel and hear them snap into place.

    • Use the flat end of a spudger to pry up and unlatch the metal locking arm on the battery connector.

    • Make sure the metal arm is completely free of the locking tab before lifting the battery connector. The metal locking arm should easily unlatch.

    • Lift straight up on the metal locking arm to pull the battery connector out of its socket on the logic board.

    • During reassembly, press the battery connector straight down into its socket, making sure it sits flush within the socket.

    • Use the flat end of a spudger to pry the Touch ID cable straight up to disconnect it from the audio board.

    • Use the flat end of a spudger to pry the audio board connector straight up to disconnect it from the board.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

Servus! Angenommen, der Stecker hat sich beim Sturz nur gelöst und man steckt ihn wieder drauf. Kann man dann Touch ID wieder nutzen? Ode muss man immer das Logicboard tauschen, sobald der Stecker abgelöst wurde? Grüße

Is it safe to remove the power button without going through the back? My touch sensor isn't working and I think something's blocking it. I simply want to remove the power key to clean... and put it right back in.
