My new 0769 E2G n200 does it too - not a major issue but it's a little weird.

I have the latest BIOS (3.03). Doesn't help. The processor is  60-70 grad hot and the cooler is on all the time.

Mine is doing the same!  Just noticed it today.  Any ideas?  It's very annoying.  I installed the lastest BIOS update serveral days ago.  Also the CPU isn't under much load.

I've got BIOS Version    68ET35WW, 4th of April 2008.

Laptop bought in November 2007

What are your versions? My laptop started overheating since upgrading bios.

Hi Guys!

I own a N200 0769 BDG (T5250) with Vista Business. Unfortunately, Lenovo really messed up the fan control. I have searched the internet for solutions and the only way to get the fan less annoying, seems to be Notebook Hardware Control (NHC).

Install the software and implement the ACPI scrip.

Now you can control the temperature when the fan is supposed to go on and off.

My settings are: on at 62°C and off at 57°C. This is perhaps a little hot but I like my notebook quiet and I haven't experienced any problems.

Hopefully, this solution works on your machines as well.

Hi!

Thank you for replying. It's somewhat hard to get through German

I registered and downloaded the .cs file and .xml file but I can't compile .cs 

Can't find ACPI class. Do you know why? TIA!

[mattmilten]

There is a folder named ACPI in your NCH folder. You have to copy the two files into this folder and change the model type in the .xml file to the name of your model.

After restarting NHC the script should work.

By the way, if someone can't find the script:

Just give me your e-mail address and I will send it to you.
