Have you tried booting your system by clicking on Last Known good Configuration? Have you tried the key combination to switch back and forth between the laptop LCD and an external monitor? On most laptops that key combination is FN and F5 (you'll need to look at your Function keys at the top to see which key it is, but its used with the CTRL-ALT and Up Arrow Keyĭo you have an External Monitor? If so, try plugging it into the VGA slot on the laptop. Sounds like you've already tried the normal key combinations that would resolve the issue. Is this a system running Windows XP or Vista?
