I've always used desktops... my first time using laptop (borrowed from a friend) During install of Ubuntu I had laptop on a chair and didn't notice the exhaust fan was blocked by the arm of chair. I noticed a smell (fabric of chair or laptop parts cooking, not sure) I got no warnings, and nothing shutdown, but I think it was a bad install... got some message... can't remember exactly. I will install again, but worried I might have damaged laptop. What is most likely: cpu or power supply damage?
