Mac Laptops First Steps
Always perform the following steps before starting a repair:
If replacing the logic board or Touch ID board, turn off Find My Mac. Choose Apple Menu > System Settings > 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.
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.
Caution
ESD (electrostatic discharge, or the release of static electricity) can damage electronic components.
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.
Warning
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.
Set aside all parts and screws removed during the repair and account for them at the end of the repair.
Only remove the battery cover immediately before you install the bottom case, unless otherwise instructed.
