This seems like sensor failure, because I do not think cpu had 128 Celsius, without going through 100 Celsius, first. > Those Random Shutdown issues at least in several cases appear to happen > due to trouble with the temperature sensor or mainboard issues. > Thermal management is in quite some trouble there, judging from > the rather diverse aspects of machine shutdown failure... > (fan not working, CPU overheating, NOT overheating but shutting down > directly after boot, ...) I had fan working at the time of shutdown, and machine was able to boot immediately afterwards. That means that 128 celsius was sensor error. -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
