Re: UX31A2 rev 4.1 fan always on

Jasko - has this worked for you and are you having any issues now ?
Thank you for the file.
Caspain - after disconnecting the LCD I was able to boot to windows. I didn't see anything, but I heard Windows play welcome sound when it got to the login. It booted quietly without the fan running. I assume it would kick in proper time when cpu's temperature moved higher .

Re: UX31A2 rev 4.1 fan always on

I don't have another screen laying around and they don't come cheap. It would be nice if I could fix this without having to waste more time and money. As much as I enjoy working on this stuff and I wasted hundreds hours on this mambo-jambo, so an alternative with the stuff I have would be epic!! I might just sell it as is, but a fix would be great.
I agree: sometimes a solution does not make sense. Please let me know if, anyone else has a good approach to this mambo-jambo.

Re: UX31A2 rev 4.1 fan always on

I didn't do anything yet and I am not sure if I want to. I am just trying to upgrade my computer from 4GB to 8GB of RAM and now I have to deal with all of this. I thought that same model board, fitting in one should be sufficient. I didn't cut the fuse or the line nor have I done anything to the light sensor. I have the original board that was in the laptop and it works fine. I see Jasko talk about clearning ME here, what would that do?
And by the way if anyone else comes across this post to look for a solution I want to let them know that...

Re: UX31A2 rev 4.1 fan always on

Thanks for replying back. I did find out that it is the LCD screen and when I unplug it I was able to hear the sound when it loaded into windows.
What are my options now, under no circumstances do I want to replace the screen and it is a similar looking computer to mac book pro. So are you suggesting that I physically remove those 2 resistors from the board because there aren't any loosely looking wires or leads to resistors and we are talking about resistors soldered on the board?

Re: UX31A2 rev 4.1 fan always on

Hi, Have you resolved the issue. I am having the same problem. After replacing the MB ux31a2 from rev2.0 to 4.1 everything seems to be working besides the fan. It is always on and I tried every driver and every setting in bios. Can anyone help?
