Asus u44sg control and stop fan

Hi! How can I control the fan on laptop ASUS U44SG-WO015V? On windows or linux is not a problem.
SpeedFan can't control the fan but show only temperatures: 50 for cpu and 49 for gpu; i tried to detect fan on ubuntu with lm-sensors but it doesn't show me them; the comand pwmconfig fails.
So exists program or guide to change the fan speed though the ACPI, EC or DSDT ?
Chipsent intel HM65, i3 2350m, intel hd 3000 and nvidia gforce 610m.
Please help me! Thansk.

 

I believe it is entirely possible. Please provide your DSDT table. You can extract it easily on Linux (you might need to install iasl, should be in repositories):

Code:

sudo cat /sys/firmware/acpi/tables/DSDT > DSDT.asl; iasl -d DSDT.asl

You can then copy-paste the text in the generated DSDT.dsl and paste it on pastebin.com

Also, provide output of acer_ec.pl that you run on Linux like:

Code:

sudo perl acer_ec.pl regsx

I will have a look at it and tell you how to control the fans on your system.

How many fans are there in your computer?

 

Make sure you have all relevant updates (BIOS, ATK, chipset, etc.) first. I'm not for certain on this model, but it may have a hotkey for Windows to control fan speeds, as many Asus laptops do.

Linux, however, may not support this, if it's available on this model.
