Here is another one with weird behavior.
There is no liquid and no dust or debris. Board looks very nice. Machine runs fine.
But when an external HDMI display is connected to USB-C (through adapter, dock or whatever I try) the machine starts to lag extremely much. It lags so much so it seems like it freezes totally. It is absolutely useless. When moving the mouse pointer it is like it just “jumps” to a new position every 5 seconds. Also the external display stays black and in the display settings no external display gets registered/recognized.
All 4 ports same issue. I also tested with an external hard drive. This one works so it seems to be Thunderbolt related but not USB related.
When I unplug HDMI the machine goes back to normal again.
Any hints to where to begin?
