Apple MacBook Air M1 2020 Repair

Apple-MacBook-Air-M1-2020-2

Introduction

This manual includes technical instructions for replacing genuine Apple parts in Mac and is intended for individual technicians with the knowledge, experience, and tools required to repair electronic devices.

Warranty Information

Damage caused by repairs performed outside of Apple or the Apple Authorized Service Provider network is not covered by Apple’s warranty or AppleCare plans. Such damage may cause future repairs to be subject to out-of-warranty costs or render the device ineligible for future repairs by Apple or Apple Authorized Service Providers.

Tools and Parts

Hardware Tools
Apple tools are designed to apply the appropriate force and torque during repairs, and to withstand high-volume professional use. The iPhone display press applies the appropriate amount of pressure to secure new adhesive during battery installation. The iPhone display press is used with a battery support frame and press plate designed for the device’s specific dimensions.

Ordering Tools and Parts
You can learn how to order genuine Apple parts and tools at support.apple.com/self-service-repair. During the purchase process, enter the manual ID JFDNFL to indicate that you’ve read this manual in its entirety and agree that you have the knowledge and experience to perform your intended repair.

Software Tools
Apple Diagnostics can check your Mac for hardware issues. A System Configuration step may be required at the end of your repair. System Configuration is a post repair software tool that completes the repair for genuine Apple parts. Running System Configuration has a number of purposes that vary based on the part replaced.

Apple-MacBook-Air-M1-2020-3

System Configuration requires a strong Wi-Fi network capable of 1.0 Mbps download and upload speeds, with less than 400 ms latency and less than 2% packet loss. Estimated data usage to run System Configuration is 6–22 MB. The device must be running the latest version of macOS and not a beta version. Learn how to initiate the System Configuration process at support.apple.com/self-service-repair.

Alerts
Failure to follow alerts could result in fire, injury, data loss, or damage to the device, parts, or other
property.

  • Adequate ventilation
  • Within 20 feet of a fireproof enclosure. Don’t store combustible or flammable materials in the enclosure. Ensure that the enclosure remains empty.

How to handle batteries

Discharge the battery

The following actions will help to discharge the battery:

  • Disconnect the power cable.
  • Increase display brightness to the highest setting.
  • Turn on Wi-Fi and Bluetooth.
  • Open the FaceTime app or Photo Booth app to turn on the camera.
  • Play a video from the local drive or a streaming service.

Use a battery cover

Avoid damaging the battery by performing the following actions:

  • Immediately after removing the bottom case, follow the instructions to attach the battery cover and disconnect the battery from the logic board.
  • Always keep the battery cover on the battery when it’s exposed.
  • Only remove the battery cover immediately before you install the bottom case, unless otherwise instructed.

Best practices

  • To avoid noxious fumes or a battery thermal event, don’t puncture, strike, or crush a lithium-ion battery or a device that contains one.
  • Keep your workspace clear of foreign objects and sharp materials.
  • Be careful when using sharp tools near the battery.
  • Don’t leave loose screws, extra screws, or small parts inside the device.
  • Don’t use tools that conduct electricity.
  • Don’t throw or drop the battery.
  • Don’t expose the battery to excessive heat or sunlight, or temperatures outside the battery’s operating range.
  • Handle and dispose of waste batteries in accordance with local laws and regulations.

First Steps

Always perform the following steps before starting a repair:

  • Back up the Mac.
  • If replacing the logic board or Touch ID board, turn off Find My Mac. Choose Apple Menu > System Preferences > Apple ID. Select iCloud in the sidebar. Then deselect the Find My Mac checkbox. If you’re unable to access the Apple menu, continue performing the following steps.
  • Discharge the battery fully.
  • Turn off the Mac.
  • If you were unable to turn off Find My Mac from the Apple menu, go to iCloud.com/find on a different device. Select All Devices. Select the device you want to remove. Then select Remove from Account.
  • Unplug the power cable from the electrical outlet. Keep the power cable unplugged while the device is being repaired.
  • Disconnect all cables.
  • Remove all cases and covers.
  • Clear and clean your workspace.
  • Put on an ESD wrist strap and attach it to a properly grounded ESD mat.

Be aware of the following while performing a repair:

  • The manual for this model may show images of other models, but the procedures are the same. Ensure that you use the correct tools for the model you’re repairing.
  • Take your time. Thoroughly read all instructions and alerts.
  • Magnetizing the screwdrivers will make it easier to work with small screws.
  • Use only Kapton tape to secure cables and keep them out of the way when removing and reinstalling parts.
  • The end of each flex cable must align with its connector. Press the end of each flex cable to its connector until it clicks to ensure that it’s secure.
