Now you got something terrible Amanus - I am experienced (Pidit) - got that problem with my PC and also got rid of it. I feel your computer has just shown the first symptom - there is more to come. It will start getting dark soon after you turn on, be it on AC or Battery. Go to System Bios by pressing F2 (continue pressing soon after you turn on your pc.) and enter Video - Brightness - Check the level - adjust to 3 or 4 (both battery and AC). If not: check whether its a hardware prob. How? Switch to external desktop monitor and see whether the problem persists. Probably, problem with LCD display, a hardware problem - if you got warranty, contact, pack and send it to the concerned authority. If you don't have, prepare to get some money out of your card.
