Accepting the kingly role I was assigned.
Was the repair shop able to reproduce the issue? Have you tried any troubleshooting yourself with regard to opening up the machine?
I would want to see if the behavior was any different with the battery disconnected. Or with different RAM (or swap RAM to a different slot). RAM makes machines do dumb stuff. Realistically in this sort of scenario, I would want to try and narrow this issue down to some component. Or the board if it still does it regardless of what components are connected.
Which specific model of ROG is it?
