Replacing G570 fan

[xepe]

Hi all, I think my G475 may be a victim. Fan on max speed all the time.

I think nobody has reported this since there is no BIOS update for my model.

Does anyone know if there is a chance the G470/G570 bug could also be the same on my G475?

Thanks

hi rzrfreefr,

Thank you for the support provided. We really appreciate it, However, inregards to your request we do not have a machine that is spefically catered to Linux OS. Our machines are catered for the WIn OS. But should your machine be running the WIn OS and facing this issue I'll be more than happy to inform our engineering team of the request. 

@ all, to those of you facing this running on Win7 please do PM with the details. Just to let u know that this is open to users residing in the US as well. If there are any users in the US please do PM me as machine in the US will be a lot faster to process and expedite.

Do let me know guys

hi xepe,

In the case for your machine it could be slightly diffrent. I'm not particualrly sure but would it be possible for to elaborate more on the issue that ur facing specically. 

But however should you feel the issue is the same, a bios update would be best to first start with. May i know what is th Bios version that you have? Currently the latest bios that we have rolled out for your model is the 41CN21WW(V1.07)_Winflash.zip. 

You may want to try it out first. You can download the bios @ http://support.lenovo.com/en_US/downloads/detail.page?DocID=DS012929

Try updating the Drivers of your machine to latest too. It can help with rectifying most issue.

DO let me know,

Regards

Hi NINE! Any new of the bios update to fix the fan control? is it so difficult to program bios in order to the  fan stop when reach a low temperature? Sorry for my english and for my impatience. Thanks

I recently ran the bios update utility 40cn32ww_64bit.exe in order to update the bios on my G570. Afterwards, when I went to look in the BIOS, it stated that it was indeed updated to version 40CN32WW (V2.18). However, the EC Version is 40EC24WW (V2.10) - leading me to believe that the EC did not update along with the BIOS. Is this a problem, and if so, is there a way to remedy it?

Hello everybody! We are waiting for any new about the fix of fan speed? Is there anyone? Don´t  forget us please!

if it matters I changed internal hdd by a SSD drive in hope it will reduce heat , but the fan is still running while watching a movie ... my 2003 lap did not

I am another g570 owner with this annoying fan.

Come on Lenovo, if you can't fix it, you could at least

release a version of BIOS with fan configuration options

unlocked, so people could tweak it.
