Just to follow up myself, I can report that I tried that and it = eventually powered off the machine uncleanly, too, so no ultimate change = in outcomes there. :-( I'm beginning to wonder if this has anything to do with the fans or the = temperature. Tomorrow I'll power on the system and let it run idle and = see if it still powers off. Do you think it would be worthwhile resetting the PMU? Cheers, Paul.
