Charging issue with MacBook Pro

I have a 2020 MacBook Pro and it keeps charging and disconnecting every few seconds making the charging beep each time. I have tried the following:

Resetting the SMC

Rotating the charger and reinserting

swapping the charger to other ports

Bought a new charging cable

and still it keeps happening.


Can anyone help?

Make sure to disconnect all other devices from the laptop in case one of them is causing a problem. Also, make sure to connect the power adapter directly to the laptop without using any adapters, docks, or hubs since they may not allow the full power of the charger to reach the laptop.


Try unplugging the Power Adapter from the electrical outlet for a minute in order to reset the power adapter's internal circuitry.


Did you try another Power Adapter as well? That is about the only other thing to try.


If none of this works, then it would indicate a hardware issue with the laptop....most likely the Logic Board although there is a chance the fault could be with the battery.


By the way....good job with all the troubleshooting steps you have already performed.
