Laptop overheating with Linux

    Toshiba L670-14L

    My very first linux install was Ubuntu 10.10 i686 from the live cd about a year ago. At first I experienced overheating and I investigated it on the net and found various solutions that worked with other laptops from Toshiba. I fiddled around with different fixes, namely grub boot options/instructions like acpi_os=Linux. I can't remember what worked but for ages I haven't had an issue. I'm obviously attributing that to updates and newer kernels rather than any fixes I applied. Looking at my grub configuration file there are no extra options and Its running fine.

    I have since tried to install Ubuntu 11.04 i686, Ubuntu 11.10 i686 and amd64. I've experienced overheating with all of them. lm-sensors picks up on nothing in my laptop with 10.10 i686 but finds coretemps in 11.10 when I run sensors-detect, sensors. Coretemp got to 80c+ and cut out at about 90. I don't run it anymore but I would need to run it for some time at least to 'debug' it but I'm afraid I'll just kill the laptop so I've stopped. I haven't started a thread about it anywhere before because I thought I would find a solution somewhere but its happening again and now I can't upgrade if I want to. Also, its a pain in the ass installing a new os only to find its incompatible for some reason.

    I can provide more info if anyone is interested. Has anyone else had these issues? What were your solutions, if any.

    HA ha! Are you serious!? Fair play to you. Have you looked into ways of fixing it or are you happy with the way you have it?

    I should say, many of the issues reported on the net refer to fans not working. My fan does, it just doesn't work hard enough. Either the OS is working the processor too hard or the fan isn't responding to it.

    Toshiba Satellite C660
    PCLinuxOS KDE4

    I can hear the fan ramping up and settling back down again depending on use.

    There are no settings in the BIOS for temp and/or fan :( which is bloody annoying!

    overheating is usually caused by lack of a proprietary graphics driver installed

    i have an amd driver, the latest one as of january 2012 now supports ubuntu 11.10 properly

    http://www2.ati.com/drivers/linux/amd-driver-installer-12-1-x86.x86_64.run

    if you want to install it, dl it, right click it /properties/permissions/enable allow executing...click on it/ select run in terminal, let it do its thing, reboot, things should be cool :cool:
