I have a 13" MacBook that I purchased last August. Lately it's been\nrunning real hot. So hot, that after awhile, I can't hold in on my lap\nbecause it gets uncomfortable. Initially, I didn't notice any problems\nbut last night Mail and Word wouldn't close. I had to force quit. I've\ndl'd Temperature Monitor and most of the temps that it monitors are\nrunning around 56C. Before I call Apple I'd like to at least know what\nthe operating range is for the various sensors. Thanks.
