[opensuse] Compaq nc6120 laptop: Overheating
Hi, I am experiencing overheating problems with my Compaq nc6120 laptop. I have installed opensuse 10.2 recently. Subjectively I noticed that the laptop is getting hotter than usual (I previously used ubuntu 5.10 - kernel 2.6.12). Under load (updating the distro with yast + running openoffice and a brower sufficies) I get temperature shutdowns after a few minutes. It seems that in termal zone 4 a critical temperature is reached (ie. more that 110 degrees C). I knew this phenomenon already from ubuntu 5.10 (and also from mandriva 2006). Adding noapic and nolapic as boot parameters helped to tackle this problem. With opensuse 10.2 (incl. all updates) this did not really change the problem (although I subjectlively think that it now takes longer for the temperature shutdown to occur). I tried different combinations of boot parameters + updated the bios to the most recent version. I also tried to exclude the acpi module fan from loading (which was one of the hints I found on the web). Using more recent kernels (from an opensuse repository) does not alter the problem either! The only "solution" up to now is to use the "energy saving" cpu throttling (800 Mhz instead of 2.1 GhZ). Then laptop does not overheat, but it is of course a lot slower. On ubuntu 5.10 together with kernel 2.6.12 everthing still works smoothly (without throttling the cpu down), so I suspect, that there is some kind of misconfiguration problem on my side, or a bug in opensuse or more likely the kernel. What do you think? Many thanks in advance!

Lm-sensors is handy for this. There is a nice frontend for KDE (ksensors, I believe) and xsensors also works for non KDE desktops regards and good luck Eberhard -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The stupid thing is, that lmsensors do not work with my laptop (as far as I know). Best, Dominik -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Best, Dominik That means, if you run sensors-detect, no sensors will be detected?
That's crazy for a modern machine imho. regards Eberhard -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Not at all, on neither of my laptops (both Toshibas) does sensors-detect find anything useful, nor on my IBM workstation. In fact, on about half of my IBM xSeries servers it finds nothing useful. The value of lmsensors, IMHO, is pretty dubious. -- -- Adam Tauno Williams Network & Systems Administrator Consultant - http://www.whitemiceconsulting.com Developer - http://www.opengroupware.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I guess this means that no sensors have been detected: http://www.grafenhofer.at/nc6120/sensors-detect Regards, Dominik -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Do you run zmd? If you do, uninstall it by pattern and install opensuseupdater by pattern. The main problem I had with zmd and zen was it pegged my CPU so hard (amd64 3200) and so long it would really heat up. Uninstalling it helped tremendously. -- Joe Morris Registered Linux user 231871 running openSUSE 10.2 x86_64 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I have uninstalled zmd already. It makes really no big difference. (This would be only treating symptoms anyway. On kernel 2.6.12 (ie. ubuntu 5.10) the laptop does not overheat (even if it gets warmer of course) even at high load.)
