Introduction

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.

Do not reuse the battery if it is swollen or was deformed in any way during the procedure. The battery is likely damaged and can be very dangerous to reuse—it should be replaced.

This guide involves removing the speakers and battery. You will need new adhesive to reinstall the speakers and battery.

What you need

Step 1

              Remove the screws securing the lower case

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
