Yoga 510-14AST Fans always on even on BIOS



Can the windows update flash my BIOS? The number of my installed BIOS suggests it's more recent than what is available to download on the


I ask that because latelly I've noticed the fans louder than normal, and from a couple of posts I got the suggestion that it might be a BIOS version thing.


What can I do to fix this situation? Please remember that the fans are on with virtually no load on the cpu, ie. BIOS.


It's also worth note that right now, I'm using Ubuntu as my main OS and going back to windows will be a last resort.


Best regards,

Re: Yoga 510-14AST Fans always on even on BIOS

Hello Bjhs

Thanks for using the Lenovo forums.

Have you had the unit for long?


It`s also possible that the unit may be a little dusty preventing the fan from controlling airflow as normal, it may be a good idea to try to clean it.


Is there maybe anything running that could be using a lot of power from the unit? If so try to turn those off and see if they can make a difference.


Hope this helps, let us know how you get on.

The unit is somewhat new.

There is no dust and I've recently upgraded it to a SSD and more ram so I've also took the chance to put some new  (hopefully) better quality thermal compound. (This unit had the fan problem before so I know for sure I didn't made it worse).


About the power, I don't use peripherals with the laptop.

You don't think it might be related to the BIOS version?


Best regards,
