The Back-light on your LCD screen is bad, your crystals aren't illuminating, so it is dark.... very dark.

You need a new LCD screen.

Sorry.

Go to Control Panel...to DISPLAY...and you should either find a adjustment there to brighten your screen. Or look On the "F-Series" keys or somewhere on your keyboard for a Brighten SUN or dark SUN, which you have to press the blue key along with that F series key to brighten or darken the laptop. Good luck
