If the issue wasn’t resolved by following a support article, continue to the next section.

1. Inspect the computer for liquid damage. Contact with liquid can short internal circuits and cause the computer to malfunction.

2. Open the display on the laptop, press any key on the keyboard, or click the trackpad or a connected mouse to wake the computer. Close the display to confirm the computer goes to sleep.

3. Check the computer’s display brightness as it may be turned down.

4. The computer may be in safe sleep, which can be mistaken for a sleep or power issue. To wake from safe sleep, connect the computer to a compatible Apple USB-C power adapter and charge cable that is connected to an electrical outlet. Then press the power button.

5. Sleep or wake issues can sometimes cause unexpected power states. Verify that the computer is in sleep mode and isn't turned off. If you aren’t sure if the computer is on or off, press and hold the power button. Wait a few seconds. Then press the power button again to turn the computer back on.

6. If the battery is drained on the computer, connect the computer to a compatible Apple USB-C power adapter and charge cable. Charge it for at least 10 minutes to verify that the computer’s battery can charge. If the computer doesn’t turn on with a power adapter after charging, continue to the next section. If the computer turns on but doesn’t complete the startup process, refer to Troubleshooting Startup Issues.

7. Follow the steps in If your Mac doesn’t turn on.

If your issue wasn’t resolved by following a support article or trying the quick troubleshooting steps, run these manual and diagnostic tests to help isolate the cause of the issue:

1. Run the Mac Resource Inspector (MRI) diagnostic suite while connected to a compatible Apple USB-C power adapter and charge cable, if possible.

If the issue wasn’t resolved or isolated by following support articles or running diagnostics tests, refer to the computer’s repair manual to open and inspect the computer. A damaged or out-of-place part may be causing one of the issues.

1. Follow repair manual procedures to remove the bottom case and disconnect the battery from the logic board.

2. Inspect internal parts and the enclosure for indications of physical or liquid damage, contamination, or burned or darkened areas. Inspect all relevant internal flex cables and connectors for damage or tampering, such as a film or foreign material blocking a connector.

   • Note: There are two open/close (AMR) sensors, each part of the left and right speakers. Both of these sensors must activate to sleep or wake the computer.

3. Locate the left and right speaker flex cable connectors and verify both flex cables are present and connected. If either flex cable is missing, it may be under the logic board. Remove the logic board to locate the flex cable.

4. Disconnect the left and right speaker flex cables. Inspect the speaker flex cables and their connectors on the logic board for any damage. Reconnect the flex cables, verifying that all connectors are seated properly.

5. If the issue is resolved or inspection reveals no issues, complete the reassembly. If diagnostic results or inspection identified a faulty part, continue to the next section. If the issue persists without identifying a specific part, continue to the next section for logic board replacement.

Note: This section requires ordering parts and tools. Replacing a part may not resolve the device’s issue. You can find other service options at support.apple.com/repair.

If the issue wasn’t resolved or isolated by following the previous steps, replace the following parts one at a time in the order shown. After you replace the first part, run the post-repair diagnostics and perform functional testing to determine whether replacing a part resolves the issue. If it still isn’t resolved, replace the next part.

• Replace the speakers (left and right), which contain the two integrated open/close (AMR) sensors.

  • Note: The speakers must always be replaced as a pair.

• If the issue persists after the speakers were replaced, replace the logic board.

Repair completion

Depending on the part replaced, Repair Assistant may be available on the device to finish the repair. Learn how to initiate Repair Assistant.

Post-repair verification

Run the following diagnostic suites after the repair:

• Mac Resource Inspector (MRI) (to test overall functionality)

• Audio (to test speakers and microphones)

After the repair is completed, turn on the computer and verify that the computer sleeps and wakes when expected.
