Re: E540: Fan does not stop

Updated to the newer 2.16 BIOS release, despite the changelog didn't mention any intervention on fan controlling: issue still there as expected.
Come on Lenovo, E540 is almost a one year old model, it's time to overcome this annoying issue!

The E530 and the E531 have the same problem! The fan won't turn off once it had been started. As mentioned above there`s only one workaround (until the fan speeds up again): go to standby mode and turn the notebook on again. :( I'm sorry, but how incapable can a company be??? They even cannot program a simple fan controller ...

The fact that same issue affects E530 and E531 too makes me think it is a desired behaviour. I also own a 2010 Compaq netbook and it has better fan controlling than E540!

Disappointed, there aren't other words to say.

The only hope is someone from support team tells us at least why we have to live with this absurd issue and, above all, why they can't solve it quickly.

Who wants to get mad real quick?

The Intel i series uses an "on the die" temp sensor. Your intel x000 graphics is built into the chip as well.

Guess what is responsible for spinning fan up and down based on temperatures from the chip's single onboard sensor?

THE DRIVER. In linux, it is CORETEMP. In Windows, it is LENOVO. Your job, no excuses.

WOW. I am speechless. This e540 will be returned and I will never touch anything from Lenovo again, not even with a stick.

Any news here? 

 

When I got my E540 everything was finewith the fan, but after upgrading to from Windows 8 to Windows 8.1 the fan won't stop anymore.

This is by design and is not going to be fixed, the problem persists in newer models among several lenovo lines.
Deal with it or change to a more competent brand.

Sorry, I wasn't clear there. While the fan is always running at a low level, after the upgrade the fan noise has subjectively increased a bit.

 

It is not nearly as much of a problem, as the irregular noise of some precedessor model (which I didn't buy for that very reason two years ago). Actually, as notebooks go, it is pretty quiet. It just feels like there is still a little bit of wasted potential.
