Troubleshooting Mac Power-Related Issues: Updated 2023


The following are potential causes of power-related problems affecting my Mac.

The charging system encompasses four key elements:

    • The battery is responsible for storing power during charging and providing power during discharge.

    • The charger supplies power to your MacBook and its battery.

    • The charging circuit is responsible for converting the charger voltage to run your Mac and charge the battery.

    • The System Management Controller (SMC) chip, governs the behavior of the charging circuit.

Steps to Diagnose Power-Related Mac Issues:

–  Verify the charger’s output voltage to ensure it’s functioning correctly. Using non-standard chargers can potentially harm your Mac.

–  Examine your Mac’s charging port for dirt or burn marks, as it tends to attract debris due to its strong magnetic attraction.

–  Confirm the proper functioning of the battery connector, which links the battery to the logic board.

–  Replace a faulty battery if you receive any of the following notifications:

    • Service Battery
    • Replace Soon
    • Replace Now
    • No Battery Available                                    –  –  If your Mac has come into contact with water, the SMC may not communicate with the battery, leading to a “No Battery Found” issue. 

In Conclusion:

If you have attempted to address the problem on your own but cannot resolve the Mac battery connector issues, it may be time to schedule a professional assessment.
