Logic Board Replacement

Introdução

Use this guide to replace the logic board in your MacBook Air 13" 2022.

To maintain Touch ID functionality, you must also replace your Touch ID sensor with a new one that's paired to the replacement logic board. If your new logic board doesn't come with a paired Touch ID sensor, you'll lose functionality. The MacBook Air'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.

Note: This laptop uses a combination of standard Torx and Torx Plus (IP) screws. In the case that you don't have all the necessary Torx Plus drivers, you can use standard Torx drivers instead. If you do, make sure to use constant, downward force to avoid stripping.

    • Four sliding tabs along the back edge of the MacBook firmly secure the lower case. Separating these tabs requires a lot of force—consider using gloves to protect your hands from the sharp edges of the lower case.

    • Keep the lower case flat and firmly pull it straight away from the back edge, one corner at a time, to disengage the sliding tabs.

    • Don't pull up until the cover is completely separated.

    • Remove the lower case.

    • During reassembly:

    • Set the lower case in place and align the sliding tabs with the screw heads they slide over. Press down and slide the lower case toward the back edge to engage the tabs—it'll stop sliding as the tabs engage.

    • When one side is engaged, it may push the other out of alignment. Check both sides as you push, there should be no gap along the back edge.

    • Once the lower case is flush with the frame, press down firmly along the perimeter to engage the four snapping clips.

    • You'll hear and feel a distinct click as each clip snaps into place.

Hi,

Is it normal that after replacing logic board and Touch ID, apple diagnostic comes up with 2 errors ndk001 als001.

One of which is ambient light sensor and the other is keyboard.

Upon testing all the keys on the keyboard all keys are working including Touch ID.

And by shining a flashlight in the light sensor the screen does get brighter.

So it looks like none of the error code is correct that apple diagnostic shows.

Is this a known thing or does this only happen to me?

Peter

For some reason keyboard error is now gone but light sensor issue persists.
