Temperature under linux

post #1 of 34

Thread Starter 
Hi all,
I'm getting desperate, sorry for the double-post with the Sentia forum.
I cannot, for the life of me, get the CPU temperature to be shown correctly under linux. I have LM-sensors installed, did the detect-sensors and modprobed the modules it wanted. I can find the thermal sensor under gkrellm, but it shows constant 11 celsius. My Sentia/Uniwill 223II0 has 1.06 BIOS and I'm running Suse 9.3 with default Suse kernel.

Has anyone managed to get the temperature read correctly under linux? If so, please, BIG PLEASE, tell me how. Did you modify the sensors.conf somehow or what did you do?

And for the record, everything else works rather nicely. Cheers.

PHP Code:
:~$ acpi -V Battery 1: charged, 100%, rate information unavailable. Thermal 1: ok, 48.0 degrees C AC Adapter 1: on-line

No luck. Is your example from Sentia/Uniwill223/S602 ?
If so, please tell me how did you manage that? What BIOS version, which kernel, which distro? lm-sensors with what drivers or modules?

PHP Code:
linux:~ # acpi -V Thermal 1: ok, 11.0 degrees C AC Adapter 1: on-line

1) Im guessing you have been too: http://secure.netroedge.com/~lm78/ and have read everything....

2) Have you ever been able to read the temps in another OS? If so which program did you use?

3) is your device listed under: http://secure.netroedge.com/~lm78/supported.html ??

In linux ACPI works if you have it compiled into your kernal IIRC & many distros dont place compile it into the kernal because of space & many never use it... Otherwise its not going to work... I would like to see if Lake-end can get it working with out ACPI, which depending on a few things he may or may not be able to get it working with out switching distros or building a new kernal because that is a b**** to do...

More to come later when I get to home, but I need to ask you abf if you mean you got that reading from your Uniwill? If so PLEASE, what distro are you using and which kernel and what BIOS? Please tell me.

EDIT: I noticed that you abf don' t have the 223 version, so nevermind.

Hi,
I seem to have the same problem with my uniwill 223ii0 under Ubuntu linux. Your post has helped me to figure it out.

You mean solution for the problem or just the problem? If the one mentioned first, pray tell, how did you do it?

Hmm, I found that acpi shows the same 11°C on the processor also under Windows,
while fan still runs as it wants at full speed and HDD temperature is shown (presumably correctly) in the range 51-54°C. I was using SpeedFan and Mobilemeter.

Lake,
I mean the problem. No idea about possible solution. Still Goooogling!

In which case I would lean towards a problem with the BIOS or hardware sensor. Check and see if there might be a BIOS update for your computer.

Sounds reasonable, I should try with the BIOS update (uhhh, too scary!!).
In fact, there is a later update. Thanx guys! Will keep posting.

I have previous BIOS 1.06 but LAke-end has the latest update 1.08.
Still we have the same problem.

Its possible then it is a hardware problem. Not much more help I can give you on that sorry, I usually dont troubleshoot thermal sensors And the only way I know of to do it, might not be a good idea with laptops

All I can say is if either of you are under warranty, call the manufacturer.

At this point i agree... That or the hardware isnt 100% compatible with linux...

Thank you, guys, for your comments!

All programs I was trying under windows were also showing the same 11°C.
So, it is in acpi. I will ask the assembling firm.
However, I would like to ask you, if you know if it is possible that the manufacturer has just disabled the thermal sensor and programmed some other algorythm of
fan's behavior. I suspect that the fan is driven by processor frequence or "load" whatever the latter means. Is it possible and is it being practices in the realm of budget laptops?
