Hi all,

          I actually took the plunge and am trying to adjust to windows 8. I found the new RSS feed for win8 drivers. I installed lenovo's new energy management software for win8, but my "moon" button doesn't work anymore. I need to be able to control the fan, especially when gaming as this notebook gets HOT, and the thermal paste on the y570's sucks. Is there a separate piece of software i'm missing? Or is this button just non-functional in win8? If it is can it be remapped? Thanx

I also have this problem. In addition, I am unable to set my battery to Optimized Battery Health and there is no dedusting option.

I am having similar heat related issues on my t520 too. Hope to get a fix soon. Power manager does not seem to work.

Edit: Found a power management driver on the website.

Dude, 

Did this fix the thermal management issue ?? Does the moon button work now. 

I have installed the new Win 8 driver from the site but my one touch thermal buttons do not work. 

Please let me know. 

Well, I have already told you, with EM for windows 7 everything works fine, including that "moon" button & various fn+f buttons.

I am having the same problem.  I am unable to adjust my fan speed and my thermal management (moon) button is flashing and does nothing.  I have tried installing numerous EM versions, none of which have addressed the problem.  I'm disappointed that with all of the forums on this topic that Lenovo has yet to release an update to solve this problem.
