Yep, sometimes it takes 30W instead of 12W... Anyway, this seems to be measurement error. Notice how acpi claims 128C. I do not think cpu can work at 128C and hardware should kill us before cpu is that hot. Are you running lm_sensors? -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
