aww thats horrible
Yeah, if it smoked, it could be anything that shorted out, to something thats completly bust and blown.
Seeing as the motherboard is the biggest component in a computer, its more than likely dribbled onto that and shorted it, and could have even gone into the CPU if you were very unlucky.
I'm afraid laptops aren't easy to fix, and so like these have said, if your mate has a guarantee, something should be able to be done. If not, well i'm sorry
