[ubuntu] Disable thermal module of acpi in ubuntu 9.10

http://ubuntuforums.org – Is it possible to disable the thermal module of acpi in ubuntu 9.10. And if so How? I think it reads the incorrect temperature or the action it takes when it tries to cool down the machine (with the fans of course) causes a conflict in the machine thereby locking/freezing the machine. The BIOS itself does enough of a job to keep the machine on temperature when needed, the OS doesn't need to assist it. (Hardware)

Hello guys,I have a question that isn't geting answered over at the Arch boards, so I figured I'd try here. The question is about different temperature readings from different applications. In the past, I have always used acpi -t to read my temps and I figured that Thermal 0 was my CPU and Thermal 1 was my GPU.

I own a acer 5720 laptop. I recently upgraded to karmic from jaunty. When I started working, I noticed some heat problems. Using lmsensors, I see core temperature increase constantly (raising even to 85 C), but acpi temperature does not suffer any change. I found this issue: ACPI: BIOS _OSI(Linux) query ignored

To find out more about your system’s temperature, install acpi. Then do a simple acpi -V to get a listing similar to this one:

Hello everyone, I'm a new Fedora user, I'm running F12 x86_64 on a Dell Studio 17 (1737) laptop and everything is fine for me with this distro except for one or two issues. When I use the suspend to RAM functionality (Acpi state S3) everything works fine but when the computer resumes from suspend state the CPU fan is not working any more and the output of acpitool is:

Hi! Due to a faulty BIOS it seems as if Ubuntu is unable to turn the fan on again after it has once been turned off, leading to the laptop becoming really hot. The fan is turned off when it goes below 50C. If I boot with ACPI=off the fan runs all the time which is fine with me.

I see two solutions to which I need some advice:

I have been having this issue since I built this computer (2 years) so I am familiar with my issue but I am new to Ubuntu (four months). I keep hoping each new kernel will be my savior, but not so far. I am looking for a fix to this long standing issue...please read on.

After installing lm-sensors and runing sudo sensors-detect i got the message:

Sorry, no sensors were detected. This is relatively common on laptops, where thermal management is handled by ACPI rather than the OS.

What is to be done in this case? (How to access ACPI?)

I'm in Lubuntu 12.04 on a hp compaq laptop

i have a problem with IBM server x306 (onboard) RAID 1 SATA HD machine. can any one advise me please, i noticed that each time i start and run this machine for up to 30mins or so, from that point on, if i do a restart (lets say after update) it simply never restart immediately but automatically turns itself off - right after POST screen.
