I turned on my uMBP today and took it over to my bed, and when I set it on my lap, there was a loud click noise (louder than the normal motion sensor click) and then a quiet clicking noise started up in the left corner. I took a look at the iStat reading and it said 0 rpm for the fan. I'm assuming that the fan just gave out. I took it in to an authorized service provider and he said that he is "concerned that it could be the hard drive." Does that makes sense to anyone? Regardless, it's well under warranty. But now I'm stuck using a crappy PC until I get it back and i'm already in withdrawal!
