E540: Fan does not stop

2014-02-13, 19:35 PM

Hello board and support team!

 

The fan in my e540 does not stop once it has started spinning. This is completely independent of system tempreature. Even though the temperature of the board and the cpu is below 40*C the fan won't stop.

The fan does not always spin, though. If I wake up the system from sleep or power it on, the fan does not spin and will not start spinning until a certain temperature threshold is reached. This part of fan control works correctly.

 

Interesting procedure: I work until the system gets hot and the fan kicks off. I waint until the system is cooled down below 40*C (checked with speccy software, the air stream leaving the notebook is cold). The fan is still spinning at this point and will probably spin forever. I suspend the laptop (no complete power off required). I immediatally "wake up" the laptop (system temperature did not change, no time to cool down). The fan is off again and will not start spinning until the temperature threshold is reached.

 

What can I do to resolve this problem? I don't always want to suspend my notebook in order to turn off the fan. It should stop on it's own.

Solved! See the solution

Another addition: When I checked whether the fan would ever stop I let the machine run over night without any load. I have installed all lenovo drivers and tools (via lenovo solution center) on windows 8.1. The problem is the same on windows and linux. I have update to the latest BIOS 1.58.

I can confirm this problem, same thing with my E540. It has an i7 inside and I observed the fan issue in Win8 and Win8.1, also after the BIOS-Update. Usually I have temperatures between 37-42°C (also varying per core), which wouldn't require the fan to turn.

 

Only Suspend & Resume turns the fan off (for a while).

 

It is much less noisy than my old notebook, but still annoying in a quiet room. And I'm afraid to catch a cold from all the cold air the fan blows out when the cpu is idling :smileytongue:

This seems to be a major problem shared by many even across various models. Would be interesting to read a comment by the lenovo community team on this. Does lenovo ackowledge the problem exitsts? Is lenovo already working on this?

The same problem here: Win7, i5, FHD, dedicated graphic card. The fan is running all the time and only suspending the computer helps for a while.

All reviews on the internet should be aware of this major design flaw on the e530 540, i don't think anyone would have bought it knowing this.
Still zero words from lenovo.

I think it isn't even a design flaw in this case. It seems to be a software bug and can be fixed with an update. Of course, that can only happen if Lenovo acknowledges this problem exists.

The problem started with the e530 maybe 1 year ago, there is a 90 pages thread about this. So i supose lenovo knows about this issue and does not fixes it and persists in the e540. It says a lot about this company.
