Satellite L300-1AQ - Fan not switching properly under Linux

For the L300-1AQ, the CPU fan is controlled by the BIOS. When booting the machine into Linux from cold, the fan spins at minimum like it should. But then nothing happens until the critical core temperature is reached. At this point the CPU fan jumps to max speed and stays there even when the air coming out is cold again. Then the only way to make the fan spin down again is to reboot.. The boot parameter 'acpi_osi=' has no effect.

This is not a hardware issue because the fan works well under Windows: slow and steady upward spins into states somewhere between min and max. After a few seconds slow and steady downward spins.

This could be a buggy dsdt sheet, which only affects Linux.

Problem is that Toshiba doesn’t support this notebook model for Linux and there is no available power management tool like Toshiba Power Saver for Windows.
Try to visit some Linux forum and discuss it there.

On Linux forums you will find more useful information or people who maybe use the same notebook with the same Linux distribution.

hi tdassler
try to use boot options li­ke "noacpi" maybe this will work...
problem is that your distribution dont have / loads the correct module to control the fan.
check if the chipset is supported by your distribution - some modules need to be loaded at boottime like "fan" "termal" and so on.
but as long as toshiba wont support linux on this machine you have to look for a solution in forums which deal with linux issius on win-hardware.

Hey there,

I just found a solution on that issue.

The omnibook-module from http://sourceforge.net/projects/omnibook/ actually does the trick.

Just open a terminal, become root and enter the following commands:

  1. cd /usr/local/src
  2. wget http://downloads.sourceforge.net/project/omnibook/omnibook%20kernel%20module/2.20070211/omnibook-2.20070211.tar.gz?use_mirror=sunet
  3. tar xvfz omnibook*
  4. cd omnibook
  5. make
  6. make install

Now the module is installed, we just need to activate it:

  1. depmod -a
  2. modprobe omnibook ectype=11

After issuing that command fan-control is working.

  1. cat "omnibook ectype=11">>/etc/modules

And this causes the module to be loaded on boot. This last step depends on your distribution, this may be set somewhere else if you don't use a debian-based one. You surely need the appropriate kernel-sources for you your distribution and a compiler for installing the module - on debian or similar installing the packages "linux-headers-2.6-your running kernel" and "build-essential" should be enough.

Thanks for the advice. The omnibook module does not compile, so I need to fiddle with it. But the suggestion looks promising.

I've tried this solution but there was some compilation error. I'm using 2.6.32rc7 kernel.

Well, I've just downloaded the svn trunk and the compilation went well. But after doing :
sudo modprobe omnibook ectype=11
then
sudo modprobe omnibook fan=1
sudo modprobe omnibook fan_policy=1

The fan is still spinning at full speed...but at least, I've got :
cat /proc/omnibook/fan
Fan is on (level 26)

And I can't change the value with echo "value" > fan...

cat /proc/omnibook/fan
Fan is off

It alwas shows as off, regardless of the spin state. But this is not what matters. What does is that the fan now switches as it should.

I should also explain how I got the module compiled and autoloaded:

wget ftp5.gwdg.de/pub/opensuse/update/11.1/rpm/src/omnibook-20080627-1.1.6.src.rpm
rpm2cpio omnibook-20080627-1.1.6.src.rpm | cpio -i omnibook-2.20080627.tar.bz2

untar, then get patch from
http://sourceforge.net/tracker/index.php?func=detail&aid=2785886&group_id=174260&atid=868544

cd omnibook-20080627
patch -p0 < ../path/to/patch
make ; make install ; depmod -a

nano /etc/modprobe.d/omnibook
put this in:
options omnibook ectype=11 fan=1 fan_policy=1

modprobe omnibook

What about omnibook svn version without the patch ? Is it expected to work ?
Actually an echo "4" > lcd is working...but I can't do anything on /proc/omnibook/fan....

I've also loaded omnibook with ectype=11 and fan=1 and fan_policy=1

Hello,

I think my last reply has not been approved - if this happens again, this will be my last post here.

Did you try Kernel 2.6.31? 2.6.32 has not been released yet, maybe there are some unresolved issues regarding that problem.

I did not need to patch anything to get this working.

sunrider,
I have not tried omnibook from SVN. Do you have a link?
Thanks,
