MacBook Air 13" Early 2020 Logic Board Replacement

简介

Use this guide to replace the logic board in an Early 2020 MacBook Air.

Note that Touch ID will not function after replacing the logic board. 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 logic board from another MacBook Air won’t work.

If you replace the logic board, you must install a paired Touch ID sensor 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 Air 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 7.1 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.
