I don't know why it should then show right now. I mean: could it somehow? Within those 1.5 years of having it, it ran Linux and FreeBSD. And always without a problem. Until now. And I really haven't touched anything in the ACPI configuration. Lenovo should be ashamed at the lack of quality control used when these > things are built.

I do agree with you that the quality has decreased dramatically since the IBM/Lenovo deal, IMHO. Still they are the better ones on the market, IMHO. Anyway... I would urge those here to consider booting XP somehow (if possible) and > running tp4xfancontrol to check actual temperatures, since FreeBSD's > h/w monitoring capability is spotty at best (I think Linux wins out > here, but at least there's room for growth...) Sorry. XP is killed completely and I would need to fix myself a HDD from somewhere and install it from scratch... What remains for me, is that it has never been a problem. Until 7.0. And if there is no hardware failure coincidence, it must be a mysterious (at least for me... ;-) ) software/configuration problem. BTW: how certain can I be that the reported temperatures are REAL temperatures? Regards, Johannes
