I have a strange problem where my laptop doesn't show a image on the screen when you turn it on, but it does if you use an external monitor and switch over to using the laptop screen and then unplug the monitor. Nothing is displayed if I don't do it this way, no BIOS screen or backlight or anything. Does anyone have an explanation for this weird behaviour? The screen isn't broken, and neither is the GPU it seems, since I can get an image just fine by switching to the laptop screen after Windows have started.
