This just started happening on mine yesterday. I left it lying on the side, charging and closed. Suddenly the fans went mental, so I went over to pick it up. The thing was so hot I could barely touch it! I quickly shut it down and waited for the unit to cool down. Ever since, when I lay it on my lap, I hear a quiet, metallic crunching sound, like a circuit board bending. It's really unnerving!
I'm currently backing everything up and will be booking into the Genius bar tomorrow.
