you should not need my script with a kernel > 2.6.21, it seems that they have fixed the problem. I’ve got the F.02 bios and it works

I have the bios07 and notice that there is often a large spread between the sensor’s cpu tempurature setting and the acpi temperature reading.
the fancontrol-bd doesn’t appear to make a difference.

Adapter: PCI adapter
Core0 Temp:
+41°C
Core1 Temp:
+47°C

/proc/acpi/thermal_zone/TZ1/temperature
temperature: 53 C
/proc/acpi/thermal_zone/TZ2/temperature
temperature: 50 C
/proc/acpi/thermal_zone/TZ3/temperature
temperature: 31 C
/proc/acpi/thermal_zone/TZ1/state
state: active[2]
/proc/acpi/thermal_zone/TZ2/state
state: ok
/proc/acpi/thermal_zone/TZ3/state
state: ok

Any followups on the hibernate problem. I have the modprobe -r button in the D state problem also.

I believe that if you change the setup in linux, it won´t affect your bios settings / your Xp settings
You should get some information here:
http://acpi.sourceforge.net/documentation/index.html ( http://acpi.sourceforge.net/documentation/thermal.html about the thermal zone)
http://acpi.sourceforge.net/wiki/index.php

Hi, your script is very interesting. Thanks. I quite new to linux and need it for heavy computations and I do not want to fry my laptop.

I have a paranoid question. If I change the setup in linux, e.g. pollig freq, trip points, etc. could I messup the machine also when it reboots to win xp? Does it affect BIOS or is it just Linux setting?

Where can I get more information about which Termal Zone is what, to better understand ‘acpi -V’ etc.

Thanks!

your script, bodom_lx, pretty much saved my sempron’s life XD. not only was my fan working faultily… I never really thought it could be a problem as it worked like that right out of the box. That was one hot sempron! my bad

It’s now working perfectly, after I followed your instructions. Thanks man!

No idea about hibernation, I never tried it..
But believe me, my script won’t remove a kernel module, just see its source code, it just put a “0″ inside a file every n seconds..

question on hibernate in stock fc6 smp kernel.

the script attemts to remove button.ko and modprobe -r button goes into ‘D’ wait state and never finishes.

an lsmod | grep button doesn’t show any module depenances or any users

lsmod | grep -i button
button 17249 0

any ideas?

Well, this is just a bash script, it won’t fix all acpi kernel problems It just helps
But I would be really glad if you found something interesting to improve it!

actually, I’m not sure anymore if hibernate is the cause of the problem, because I tried hibernating and then starting up again (from hibernation) and it seemed to work fine this time. Even tried running “openssl speed” to make the processor work hard, and /proc/acpi/thermal_zone/tz1/temperature correctly showed increasing temperature and the fans correctly started at the intervals specified in /proc/acpi/thermal_zone/TZ1/trip_points. I will let you know if I figure out the real cause of the problem.

Hhhmmm..never tried kernels with hibernate support..
I’d be happy to add extra fixes to the script, if somebody reported them in this page..

it also seems that the reason behind the pro.blem described above is that the information given in /proc/acpi/thermal_zone/TZ1/temperature is incorrect, as is said 44C even when it was so hot I was afraid to touch the left side of the keyboard…

Great script! I’ve implemented it and it seemed to work, but sometimes the laptop still overheats without the fan even starting.
I have an idea that this may have something to do with hibernate, but I’m not sure. Basically, I used to hibernate the computer instead of shutting it down, but then, on occasions, it became very hot, and the fan was not working.
When I shut it down properly, and restarted it, the fan went on, probably on max, until the temperature was down to normal.
Does anyone have any idea on how to fix this?

Excellent! This works great on my nx6325 under Fedora 6.
Thanks so much for sharing your findings!

Bitteschön Toks, es ist immer eine Freude für mich, eine Bedankung zu empfangen!

Better if I continue in English, my German “ist ein totaler Mist”..

Well, a positive feedback and a “thank you” are always the best way to make me feel happy to help somebody.. I discovered this method just for fun, and I’ll surely continue to help people, when I’ll be able

Enjoy our fantastic notebook with the best OS in the world

Interesting stuff.

I use a HPnx6325 and I’m new to Linux. I never even bothered about the temperature, just because I didnot know how to tweak it.

Thanks a lot.

As for the decision in English – its a great decision!! Becuase atleast I benefited from it!! THANK YOU
