I have a Dell XPS 9550 running Linux (Ubuntu). I notice occasionally/randomly, my xps 9550 laptop screen will shut off while I am working on it. I have an external dell monitor plugged in via the HDMI port. How do I figure out if it is a bad screen, a hardware issue, or an OS issue?
Excellent procedure breakdown AdrianG001. However, there is that small issue of him running Linux (Ubuntu I think it was). Your procedure is valid for Windows, I guess.
