Laptop FAN PLEASE HELP!!!
 
Hello.
I have a Fujitsu Siemens Amilo L7300 Laptop.
Can anyone tell me how to make the CPU Fan stop after it cooles down?
I have tryed stuff from other forums bit in /proc/acpi/fan/FN1/state and FN2/state i always get OFF!!!
And my fan is running like crazy !
Please tell me what to do !


And second thing.
have anyone any ideea how to make my wireless card RaLink 2500 to work under Slackware 10.2 ?
Thanx in advance !

Sure, Eric (Alien Bob) has some packages in his slackware software repository for the rt2500 (http://www.slackware.com/~alien/slackbuilds/rt2500)

But compiling from source is not hard at all and will work even if you use a different kernel from the Slackware stock one:

http://rt2x00.serialmonkey.com/wiki/index.php/Downloads

Try the CVS daily snapshot and see if that works (it's working fine with me, and is better than the official RaLink driver, but things could change pretty suddenly in CVS), if it doesn't want to go, try the BETA -although is quite outdated.

Note that with this driver the interface is called ra+ rather than eth+ or wlan+ (where '+' is an nonegative integer)

Sorry, I don't have a clue with the first issue.

Is your kernel configured with ACPI submodules for things like fan and button? Check the ACPI section of your kernel's .config.

For issue #1:
Look at my homepage (Link in my sig). As long as you have ACPI enabled (And by your post, it is) the script in there for the fan will shut it down.

For issue #2:
Use either Eric's build, or get the latest source from here
Extract it, go into Modules, and type
Code:

make -C /usr/src/linux SUBDIRS=$PWD modules
make install

then
Code:

modprobe rt2500
Let us know how this goes, more maybe needed.

Thanx i have tryed your script for the FAN BUT !!!!
after i run the script my fan state will be on OR off but the fan is still speaning !
I am using kernel bareacpi.i ( from boot disc)

Don't have any experience with your hw, but did really get temperature of your NB down ? If CPU runs on higher or max frequencies, it should ignore all attempts to disable fans in sw way due to possible overheating. If not, look for cpufreq support.

Can you be a little more explicit because i have no ideea what you are saying there. I am kind of a newbie in Slackware and Linux to

Thank you

Linux supports with kernels 2.6 (or patched 2.4) procesors with frequency scaling ability. When running at lower frequencies it partly saves batery consumption and at the same lowers release of heat.
You need in kernel enabled support for your CPU type and also CPU frequency scaling with required governors(scaling policies). The least complicated way would be to install 2.6 kernel-generic and kernel-modules packages from testing/, reboot into new kernel and load CPUFreq procesor driver and governor modules with modprobe.
My case:
Code:

modprobe speedstep-centrino
modprobe cpufreq-conservative (or cpufreq-powersave)

That's all folks.

OK so you are saying that probably my CPU is extremly hot and that's why it ignore the fan commend to stop or run ?

when i check the /proc/acpi/thermal_zone/THRM/temperature it say 33 or 35 but NEVER above 40 degrees

Yes, but it was just a suggestion what could be the source of the problem and it was the most frequent one I've experienced so far.
I would also recommend to look at TuxMobil.
