Thanks for help! It works perfectly well. I haven't used NHC(Notebook Hardware Control) before and didn't know that the folder acpi is created after the installation of this software.
Here is the link to NHC: http://www.pbus-167.com/
Can't we copy the files from the forum or do you want people to register there? I respect the right to do that and just ask before possible uploading it somewhere where it's more available for the people who don't understand German at all .
It would be good to place it here.
I haven't really figured out what's the difference between FAN_ON_TEMP_MINIMUM and FAN_ON_TEMP classes ?
What are default, min, max values? I set all of them except max to 60 C but I'd like to know

Well, I didn't write this script and so I can't explain it to you. If I knew how to upload the script to this forum, I would have done that already but as far as I know it isn't possible...
I didn't change any values in the script directly, I just adjusted the temperatures inside NHC.
UPDATE: I have uploaded the script

Ok, I get it now.
First open NHC, then go to ACPI fold, then "Show ACPI Control System details", then "Fan config".
FAN_ON_TEMP - FAN ON -at this temperature the fan is turned on
FAN_ON_TEMP_MINIMUM - FAN OFF - at this temperature the fan turns off
Min - minimum value you can enter
Max - max value you can enter
Default - what values are on default
But the basic indicators are : temp for FAN ON and temp for FAN OFF
I'll write to the author about publishing it here.

First of all, read this thread from the beginning.
You are doing it at your own risk, no guarantee is provided.
I'm not the author of this solution. I only found it helpful and wanted to alleviate the pain for everybody else stuck with this problem. The original thread here
Thanks mattmilten for letting us know about this solution and thanks Hallo32 from thinkpad-forum.de for the code!
If you have any questions ask here.
Lenovo.xml (Copy the code below and paste it in a txt file - name it Lenovo.xml and put it into C:\Program Files\Notebook Hardware Control\acpi . Change the text in bold to your version of laptop)

Hi, people. I have just bought a N200 0769 AAP and noticed that its processors get extremely hot. They stay between 50 and 60 Celsius at normal activity, but get as high as 90 degrees when doing some intensive processing (as when installing software). It is unexpectedly turning off because of this (it might be reaching the critical temperature of 100 Celsius). It has even turned off during Windows Vista start-up. I am really disapointed with this situation. I have read that you got to a solution by using a piece of software, but I think it works under windows. Is there any similar software under Linux? I do much appreciate your considerations.
By the way, is Lenovo going to fix the problem. I didn't contact the support yet, since it's been four days since I bought my N200. But if I didn't find a solution by my own, I am going to complain by their desks.

Has anybody managed to carry out this procedure on Linux? I got to know that ACPI parameters may be set through /proc/acpi directory, but there are no files related to the setting of the so called "trip points" or fan speed. My notebook keeps shutting down by reaching critical temperature. This tipically occurs under intensive regimes, as when running a lot of applications at the same time or running a videogame. I am really upset with this situation. Just avoiding the pain in the neck of carrying it to technical support and waiting some days to get it repaired in case it 'features' a defect.

Perfect! NHC works with the script above. Many many thanks guys, especially german folks, who managed to fix what Lenovo failed.
I mean jeez, increasing the threshold just a few degrees made so much difference. I can't imagine why this hasn't been fixed in bios updates.
