HELP HELP HEEEELPPPP PLEASE I BEG

My laptop won't work. I don't know what happened to it. It was fine at school, and I go out to the car, go to turn it on (so I can work on the first chapter of the Bite Hard sequel), and... it doesn't turn on. The light turns green, but nothing else happens. I close it. The light stays green. Still nothing happens. I go home and plug it in, and still nothing happens.

I'm freaking out.

It's a Sony Vaio, and it's still fucking NEW, so I shouldn't be having this problem. I'm scared it's some kind of virus, by my computer has virus protection and has shown absolutely no signs of having a virus. I really don't know what to do.

Computer people, can you help me? I have a philosophy study guide on there that I need to look at intensely before the test tomorrow (NOT TO MENTION ALL THE OTHER STUFF I HAVE ON THERE).
