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

2. Verify that the power adapter and charge cable are the correct types for the computer. Different power adapters and charge cables may appear similar but may not provide sufficient power to turn on or charge the computer. Note that only some power adapters and some charge cables provide fast charging ability. Refer to the support articles above for more information about how to identify Mac power adapters and fast charging.

3. Inspect all USB-C ports and top case openings on the computer for any signs of deformation, damage, or debris that may be blocking the connection. Gently clean each connector using a small, nonmetallic, soft-bristled brush. Ensure that the brush is clean and dry. Use just enough bristles to fit inside the connector. Twist the bristles to loosen and lift out debris. Brush debris away from the connector to avoid brushing debris into the connector.

   • Caution: Before cleaning ports, disconnect all cables and turn off the computer. Don’t use aerosol sprays, solvents, abrasives, or cleaners containing hydrogen peroxide that might damage the finish. Don’t use any metal objects to clear debris or obstructions, as this can short the connector and cause damage. Avoid getting moisture in any openings and don’t spray liquid directly on the computer. Don’t use compressed air in port openings as it may drive debris further inside the port.

4. The computer may have power but may only appear to be off. Verify that the computer is turned off. If you aren’t sure if the computer is on or off, press and hold the power button to turn off the computer. Wait a few seconds. Then press the power button again to turn the computer back on.

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

1. Determine if the computer has power by confirming any of the following:

   • The computer indicates when a charge cable is connected (for example, with a sound)

   • The built-in display functions

   • Note: MacBook Neo uses a mechanical trackpad that always clicks whether power is on or off. Don't rely on trackpad clicking to verify power in this model.

2. If the computer shows any indications of power, refer to Troubleshooting Startup Issues.

If the issue wasn’t resolved or isolated by following support articles or running manual 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.

3. Locate the USB-C boards flex cable connector and verify the flex cable is present and connected. If the flex cable is missing, it may be under the logic board. Remove the logic board to locate the flex cable. Disconnect and reseat the USB-C boards flex cable connection to the logic board to verify its connection.

4. Test whether the battery is preventing power. With the battery still disconnected, attempt to turn on the computer with the charge cable connected. Then, with the charge cable still connected, reconnect the battery and attempt to turn on the computer. If the computer turns on with the battery disconnected, and fails to turn on with the battery connected, battery replacement is recommended. Continue to the next section. If the computer doesn't turn on whether the battery is connected or not, suspect a USB-C boards or logic board issue. Continue to the next section. If the computer turns on but doesn’t complete the startup process, refer to Troubleshooting Startup Issues. If the computer turns on and completes the startup process, the battery connection may have needed reseating, causing the power issue.

5. Optional: Test whether the battery is charging. Connect the computer to a compatible Apple USB-C power adapter and charge cable. Charge for at least 30 minutes. Then with the charge cable still connected, attempt to turn on the computer. If the computer doesn’t turn on after charging, service is recommended. Continue to the next section. If the computer turns on but doesn’t complete the startup process, refer to Troubleshooting Startup Issues. If the computer turns on and completes the startup process, the battery may have been drained, causing the power issue.

6. If the computer successfully turned on during internal inspection and testing, the issue may have been resolved by reseating the USB-C boards flex cable or charging the battery. Reconnect the battery (if disconnected), complete reassembly, and verify functionality.

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 for each relevant issue:

Important: Always attempt to revive or restore the computer by following steps in How to revive or restore Mac firmware before attempting any hardware service.

• If you find damage in the charging ports, replace the USB-C boards.

• If testing indicated battery issues, replace the battery.

• If no specific faulty part was identified above, 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 suite after the repair:

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

After the repair is completed, turn on the computer and verify that the issue has been resolved.
