Can you do me a favor and test something for me? Boot up with nothing connected, then connect to the dGPU port, then try launching anything that uses the gpu (game, nvtop, etc).
Does it fail to run? Does it hang/lock up and cause the laptop to act funny and fail to power down/reboot properly?
I am having this issue and it is pretty major, posted about it here:
I just want to confirm if I have a defective dGPU or if this is an issue Framework needs to fix? No one has responded to my post about it.
