You are probably one of the many who are looking for the dust extraction on your Y580, as you expect it to have just like in the Z series of laptop. First you must have the latest version of the Energy Management, or if you have uninstalled it make sure to download it from here.
Run the program, wait for it to install. Once done it should look like below:
It runs about 5-7 minutes for the dust extraction, with noticeable sound at the left side. I’m pretty impressed with the fan of Lenovo Y580, it is not overheating even after running for hours of graphics demanding games like Dead Island or CSI.
Hope that helps. Post a comment or feedback regarding the dust extraction in Lenovo Y580.
