What you say is true, Long-Term Mac User, Intel chips do run hot(Apple is now apparently shying away from the term "laptop" for that reason), but RSS is not a normal operating problem.

"Random Shutdown Syndrome" is just that--it occurs randomly--not just when the unit is hot. My "problem unit" *was* a MacBook Pro. On one occasion, it shut down on eleven consecutive start-up attempts. I tried all the fixes, and Apple did major repairs and replaced a bunch of hardware, but none of it worked, and they ultimately replaced it-and my new unit hasn't given me a lick of trouble--
