Since the bios update my controllers won't work until I open Legion space.
This one of reason why i dont updatr bios. I just love with the bugs. Usually i dont run into the bug anyway.
People It's not bricked if you recover it.
I'm sure I had that blank screen problem before but it wasn't blank. I plugged it into a monitor and the screen showed up there. As is was set to second display only after update for some reason. Think it's due to aspect ratio being portrait rather than landscape.
