Samsung R40 boot after keypress only
At one of my schools they have a Samsung R40 laptop that will only boot after you press a key. There's no error message it just sits at the samsung splash screen and the backlight turns off. As soon as you press a key it boots as normal and everything works fine.
I've tried updating drivers, installing Samsung display management software and changing the brightness control options in the BIOS, but nothing has worked. I can only assume a hardware issue now but apart from the backlight turning off and not booting until you press a key, everything else works fine.
Has anyone encountered this behaviour before?
