As soon as my laptop computer battery reaches 100%, when unattended, each 5 to half-hour, the MagSafe 3 cable gentle briefly turns off, turns again on, the “100% Charged” message will present on the display, and the pc will chime. (Much like this different unanswered submit). This turns into pretty annoying, and I am additionally involved will probably be dangerous for my battery.

I’ve a 2023 MacBook Professional M2 Max, and utilizing the charger within the field. I did a recent set up once I bought it.

When troubleshooting:

  1. Occurs on a number of completely different shops
  2. Occurs with a number of completely different chargers
  3. This occurred each on Ventura and once I upgraded to Sonoma
  4. Introduced the laptop computer to an Apple Retailer and so they discovered no points when operating diagnostics
  5. Apple Retailer cleaned the MagSafe connection
  6. Apple Retailer carried out a Firmware Revive

I believe there could also be some software program or setting triggering this conduct. I used to be looking for some related logs and located these by typing pmset -g log. I am unsure if these are regular or level to something.

Close to the top of the logs you possibly can see Utilizing Batt(Cost: 100) adopted by Utilizing AC(Cost: 100) only a second later, and a message concerning the energy chime.
