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.
