I’m experiencing a strange issue with my Mac Mini M2. One of its Thunderbolt ports has completely stopped working, while the other is partially functional—it only works with low-power devices, like SSDs. High-power devices don’t seem to work at all.
Everything else on the system is working perfectly. Can someone provide me with the schematics for the logic board or suggest a solution? I’d prefer not to replace the entire logic board.

It sounds like you may have a bad device or cable that is tripping the port overload protection.
To reset the ports > disconnect all devices > Shut Down > wait a minute > then turn the Mac mini back On.
Then start testing your devices one at a time, in an attempt to discover which device or cable is causing the problem.
Make an appointment at your local Apple Store or Apple Authorized Service Provider.
I've tried everything got no luck...
They told me that the entire logic board needs to be replaced, which would cost about the same as buying a new one. So, I decided to order an M4 Mac Mini instead.
