Battery replacement MacBook Air 13 Early 2020

Before beginning this repair, disable the Auto Boot option on your MacBook.

Auto Boot activates your Mac when you open the screen and could be unintentionally activated during disassembly.

For MacBooks that have Big Sur v11.1 or later, turning off Auto Boot may not be effective. You can continue with the steps, but remember to disconnect the battery as soon as you can access it.

1. Fully power down and unplug your MacBook charger before you start. Close the screen and flip the laptop over so it’s upside-down.

2. With a T5 screwdriver, remove these screws:

- Two 7.9 mm screws

- Two 7.1 mm screws

- Six 2.6 mm screws

During the repair

Carefully track each screw to ensure it’s returned to its original position, preventing potential damage to your MacBook.

1. Insert your opening tool between the display and the lower case, then separate them.

2. After creating enough space use your fingers and pull the case upward to detach it.

3. Take off the whole lower case.

To reattach the lower case

Align it properly and press down firmly to secure the two hidden clips underneath. You should feel and hear them click into place.

Use tweezers to unstick the tape covering the battery connector just enough to reveal the connector underneath it.

With spudger gently push the battery connector parallel to the logic board and disconnect it from socket.

When the MacBook is upside down, the left speaker will be on your right-hand side.

Gently insert the pointed end of a spudger beneath the left speaker cable and lift it upwards to detach it from the logic board.

Once the connector is free, use the flat end of the spudger to gently lift the cable, breaking the adhesive that holds it to the logic board.

Use a T3 Torx screwdriver to unscrew the 4.2 mm screw that attaches the left speaker to the chassis.

Using tweezers, lift the black tab of the stretch-release adhesive on the speaker until you can hold it with your fingers.

Pull the adhesive tab slowly and carefully to release the strip from under the speaker.

Ensure the adhesive strip stays parallel to the MacBook, and avoid dragging it across the interior of the case.

Continue pulling the adhesive strip until it’s fully removed from beneath the speaker.

If the strip tears, apply heat with a heat gun or a hair dryer to soften the adhesive.

Carefully slide spudger or opening pick under the speaker and separate the adhesive.

Use a pair of tweezers to peel back the black pull tab on the speaker's stretch-release adhesive until you can grip it with your fingers.

Grab the adhesive strip’s pull tab and slowly pull the adhesive strip out from underneath the speaker.

Keep the adhesive strip as parallel to the laptop as possible, avoiding dragging it across the inside of the case.

Pull the adhesive strip until it is completely freed from under the speaker.

If the adhesive strip breaks, apply heat with a heat gun, or hair dryer to soften the adhesive.

Carefully slide a spudger or opening pick underneath the speaker to help separate the adhesive.

Remove the left speaker from MacBook.

When Reasembling

Make sure to apply a new adhesive strip from double sided tape to the bottom of the speaker before securing it back into the case, ensuring it functions properly.

The left speaker will be on your right-hand side when working on the MacBook, as it's laying upside down.

Using tweezers, lift the black tab of the stretch-release adhesive on the speaker until you can hold it with your fingers.

Pull the adhesive tab slowly and carefully to release the strip from under the speaker.

Ensure the adhesive strip stays parallel to the MacBook, and avoid dragging it across the interior of the case.

Continue pulling the adhesive strip until it’s fully removed from beneath the speaker.

If the strip tears, apply heat with a heat gun or a hair dryer to soften the adhesive.

Make sure to apply a new adhesive strip from double sided tape to the bottom of the speaker before securing it back into the case, ensuring it functions properly.

Use a T3 Torx screwdriver to unscrew the two 1.4 mm screws holding the trackpad cable cover in place.

Use tweezers to remove the cover.

Use the flat end of a spudger to gently lift the trackpad cable connector out of its port.

Slowly peel the trackpad cable away from the battery.

The cable is lightly attached to the battery with adhesive.

Use a T3 Torx screwdriver to remove the two 2.5 mm screws that are fastening the battery tray to the case.

The battery cells in MacBook are secured to a metal tray as one unit, and this tray is held in place by six stretch-release adhesive strips.

Do not try to detach the battery cells from the metal tray.

On the left side of the MacBook, use tweezers to lift the three black pull tabs on the adhesive strips until you can grab them with your fingers.

Take hold of the pull tab on the adhesive strip and gently pull it out from under the battery.

Keep the strip as level with the laptop as possible to avoid scraping it against the inside of the case.

Continue pulling the strip until it is completely detached from beneath the battery.

Do the same for the other two adhesive strips on the left side of the battery.

Perform the same steps to remove the three adhesive strips from the right side of the battery.

If any of the adhesive strips tore while removing them, you can use a plastic card to carefully finish separating the battery tray from the case.

Carefully remove the battery from the MacBook.

To install your new battery follow these instructions in reverse order.

When reassembling

If your new battery doesn’t have adhesive pre-applied, you can use double sided tape to secure the battery tray in place.

After the new battery is installed follow the calibration procedure:

- Charge the battery to 100%, and then continue charging for at least 2 more hours.

- Unplug the charger and use the MacBook normally to drain the battery.

- When you see the low battery warning, save your work and keep the laptop on until it goes to sleep due to low battery.

- Wait at least 5 hours, then charge the laptop uninterrupted to 100%.
