    Toshiba Satellite L505 overheats

    Hi guys,

    I installed Ubuntu Karmic Koala on my Toshiba Satellite L505-S6946 several days ago, and it seems to overheat. The bottom gets quite heated, and so does the palmrest. I dual boot with Windows 7, and when I'm running Windows 7, the laptop is as cool as it has always been. So, I don't think the issue is hardware related.

    Any help will be much appreciated.

    Thanks.

    Try to add either "acpi_osi=Linux" or "lapic" to the boot command line:

    - open /boot/grub/menu.lst with a text editor (sudo it, because it is owned by root)
    - add one of the option (first try with "acpi_osi=Linux") to the end of the row starting with "kernel"
    - try the other option if this does not work
    - give us feedback about your results

    Hi,

    I tried the command above, and it opens up an empty file. I browsed to boot/grub/ and couldn't find menu.lst. I looked into the hidden files, too. Am I missing something very obvious here? :S

    Thanks

    You are using grub 2, and I have no experience with it, sorry.


    Try looking at:

    or simply get to the interactive boot menu at boot time and
    try adding the acpi_osi=Linux or lapic to the boot parameters.

    I'm having the same problem with my Toshiba L505. Overheats when running Ubuntu, works fine when running Windows 7.

    I tried adding the "acpi_osi=Linux" and "lapic" options, but no luck, still overheating.

    It's most noticeable under heavy CPU usage, like when compiling. It also happens when running XBMC. I don't even have to be watching a movie, just having XBMC running idle will cause it to overheat after about 5 minutes.

    I stopped using ubuntu natively after a while, but for some reason, the heating reduces, but doesn't go away completely.
