My Toshiba's fans do not work automatically

Question

My Toshiba Satellite m505-s4940's fans do not turn on automatically, so it was overheating before I learned how to do it manually by using this keyboard-shortcut:fn+F3

I have to do this every time I use my computer!

I really like the performance of Ubuntu, and I just began to use and love it, but I would like to solve this problem.

Hopefully someone can help me, and sorry about my English. It is not my native language : )

Solution

This has been reported here and here and here (kernel).

There appears to be one workaround:

1. Boot up
2. Suspend
3. Wake it up
4. ACPI should work (fans should work, the lid should sleep it, etc)

If this doesn't work, I recommend you don't run Ubuntu until it's fixed as letting it overheat is very dangerous to the hardware.

Of course if you can help the kernel devs find a fix for this, the faster you get the fix.
