i have a Compaq presario V6000

and i was working on my college homework.
i closed the lid and left.
when i came back it was off and i turned it back on but the screen stayed black and the num and cap locks turn on but them the whole thing turns off like 15 to 10 seconds later after i just turn it on and does some kinda of reset/ reboot.

dont get a beeb error.
neither can i get to bios since the screen looks like it doesnt turn on.

anyone know what i can do to fix it or what is wrong with my notebook.
