In brief: Read the screen.
In case you're wondering HOW my laptop got cooked... ...I was at school sitting on the floor doing homework and my brother threw a toy lizard called Jacinta at my laptop. The screen went all fuzzy. I turned it off and on again, and now it won't turn the screen on at all and every time you touch Power the keyboard lights flash and it beeps loudly. So sorry guys. I have stuff I wanted to do, I'm so annoyed, but it couldn't be helped.
