That’s slightly different to my experience. Firstly, disconnecting and reconnecting will not bring the devices back. Secondly, I don’t get the “scratching” sound nor any prewarning that the devices will drop.
That said, both ports do drop from the OS as I’ve noted in the Device Manager screenshots. And I can’t get them back easiy. Disconnecting and reconnecting doesn’t help nor does rebooting. Reinstalling drivers seems to bring them back sometimes. Reinstalling the BIOS also sometimes works.
Edit: Just because I see somewhat different behaviours does not mean that you are on the wrong track re power @sun. The Framework Desktop is a desktop but Strix Halo is mobile (as @rjones suggests) so all ‘mobile’ related assumptions are worth checking to ensure they are applicable to ‘always plugged in’ reality.
