You probably fried your power adapter. (the big metal block in the corner of your computer)

send it in to apple. If you're feeling adventurous you could probably go buy a PC one and replace it, but I don't know the specs of it and wouldn't recommend it.


edit: on another thought, the power adapter usually has fuses in it that can be replaced. BUT opening it is EXTREMELY dangerous as the capacitors in there usually hold charge long after it's been unplugged. so don't do it.
