Re: E540: Fan does not stop

2014-12-31, 9:30 AM

Currently I've found contradicting feedback for Windows 7 in this thread:

  • Accordging to gih the problem occurs on Windows 7.
  • According to elliotjyoung it does not.

Can anyone who is affected by the issue on Windows 7 check, if power manager settings (should be preinstalled) can solve the issue?

 

Likewise, are there people with Windows 8 or 8.1, who don't have the problem?

 

And, did anyone using Linux find a solution?

Forgot to mention, I run a windows 7 64bit.  I've tried power manager settings but haven't found a solution. You can choose system cooling policy (active vs passive). Active slows down the processor after speeding up the fan, and passive slows down the processor before speeding up the fan. Neither of them stops the fan after it has started spinning (at least for me).

Re: E540: Fan does not stop

hello everyone!

 

I bought a lenovo tp edge e540 back in june 2014 and installed windows 8.1. since my first experiences with this laptop I experienced the same fan issues like everybody else, I guess. I start the laptop and everything ist fine. BUT after at least 5 minutes (core temp around 40 °C) the fan starts to work endlessly. To stop it I go in suspend mode, but this only helps if I stay in this! haha!

I write beacause my HDD made funny clicking sounds last week and I substituted it with a SSD, because I have no time to send my laptop to lenovo. Now with an SSD the continiuosly blowing/spinning fan is driving me nuts. Maybe without the melodic clicking the more or less high pitched sound only touches my anger! I don´t know! I have all of the latest updates and of course the latest bios version (J9ET96WW or 2.16) and just wanted to let everybody know that you´re not alone!

It´s obvious that this is a software problem and it seems that lenovo will only work on this problem, if literally everyone with a e540 tells them to start getting s**t done! Dear administrators, I know you have no big influence on the lenovo custom support, but I don´t think that everyone with this problem is going to send a complainment to the support team! But I would really appreaciate your assistance in telling us how to be heard with our problems by lenovo and the software-developers, who simply have to fix the controlling of the fan!

 

thank you very much! I know you guys are going to give you´re very best!

 

p.s. sorry for my english, but I guess you get my point!

hey friends! it seems to me, that the new BIOS update 2.17 solved my problem of the endless spinning fan! it´s so relaxing! a little optimization work could make the fan control perfect, but i don´t want to go on about that! maybe in BIOS update 2.18?! ;) so for the moment: thanks a lot, lenovo! good job!

 

\\Edit: Okay! To test different workflows or workloads I played a game (trackmania nations) and after quitting the game the fan won´t stop. To ensure this I reapeated this several times. To fix this issue I had to go in suspend mode! afterwards the fan control works again! I don´t see the origin of this problem... looking forward to the next BIOS update! hehe

This helped me too

Wow.... things have happened :) I can confirm a major improvement in fan
handling. Haven't tried gaming yet, though. Thanks, lenovo BIOS guys!
(Although it took you a while ;)

Re: E540: Fan does not stop

I performed the BIOS-Update today (version 2.17) and am enjoying the silence finally.

 

The release notes contain the following comment:

 

[New functions or enhancements]

...

- Modified thermal table.

 

I can confirm that the fan behavior has changed, on my system it behaves like this:

 

  • above 57 ° C: fan kicks in
  • below 50 ° C: fan stops

 

Before it was (almost) always running even when the cpu package was at 40 ° C. Now I can do most of my office work in silence. When I startup a VM in VirtualBox the fan usually spins up. Same for watching youtube or other heavy web apps (vimeo allows me to watch HD without fan - hey youtube, shame on you). I didn't test the behavior when using the dedicated GPU, usually I'm woring with on-chip graphics. The left third of the keyboard feels a little warmer now, but nothing that would be annoying or make me worry about system lifetime. Also the air coming from the outlet didn't cause any burnings so far.

 

I find the thermal handling for a quad core system like mine now an acceptable compromise, well done Lenovo (late but ok).

 

My specs:

  • E540, Windows 8.1, FullHD Screen
  • i7-4702MQ (quad core 2.2 GHz)
  • 16 GB RAM
  • 254 GB SSD (M.2)
  • 1 TB HD (usually not spinning)

regards

Does anybody know if the E530 has been fixed?

Re: E540: Fan does not stop

Using the 2.17 update, for me after heavy loads like games the fan gets stuck in fast-mode. Curiously, starting a game again and shutting it down before it can create much heat, can return the fan to normal behaviour. This is however pretty much the same behaviour as before the update, though I do have the impression, that the fan is more quiet overall than before.

 

My best guess: Activating the dedicated graphics card triggers something, that makes the fan behave properly again. 

 

Is it possible that the thermal sensor of the dedicated graphics card is shut down along with the graphics card? It wouldn't make much sense, but it would explain the behaviour ("fan control stuck, because it thinks the card were still hot.")

You´re right! Starting the game again helps! the fan control works afterwards!

thank you

I verified, that regardless of program used, any program triggering use of the dedicated graphics card restores normal fan behaviour -- even if I start notepad.exe on the dedicated graphics card. 

 

So this seems to be an issue with NVidia Optimus. Could it really be that the thermal sensor of the graphics card is disabled along with the card, resulting in outdated temperature readings?
