Use this guide to safely remove and replace the battery from a Late 2020 MacBook Air (M1).

To minimize risk of damage, turn on your MacBook and allow the battery to fully discharge before starting this procedure. A charged lithium-ion battery can be very dangerous if accidentally punctured. If your battery looks puffy or swollen, take extra precautions.

This procedure involves removing both speakers. You will need new adhesive to properly reinstall the speakers to avoid excess vibrations or rattling.

    • 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.
