I think it's because of Lenovo Power Management is not working correctly. I can't set the fan to efficient heat dissipation hence causing the CPU/GPU to throttle back, producing stutters in Games and even websites that have a high flash content.
Is there a fix for this? I tried removing Lenovo Power Management and it did not work. I installed the Windows 8 version from the Lenovo Site. I noticed the fan mode button does work when I press it. It does however flash low/high every few seconds.
Solved! Go to Solution.

This is not a hardware problem. In windows 7 it works fine. It's software/drivers not enabling the fan fully, and throttling the CPU/GPU so it doesn't over heat.

There's no way to use the fan control button within windows 8, even if you revert to the windows 7 software. This is a widespread issue adn I called support and they couldn't help.

thanks for posting. As you know the Win8 is a relatively new OS with many new fuctions. I would like to break this down a bit so we can isolate the issue to be hardware affected or software related. Now from what have been discussed here it is pointing more towards the software and as some of you have pointed out it does seem like a software issue rather than harware.
But just to get a better understanding of the case here, The Win8 you have installed in your machine, did you do a fresh install or proceeded with the upgrade promotion Microsoft? Upon installing the energy management from the support site did any errors appears? Upon checking the device manager was everything installed or were there some drivers that was not installed.
Please do let me know.

Hi NINE. Thanks for your reply.
I did a clean install of Windows 8 x64 Pro.
I downloaded the Windows 8 version of Lenovo Energy Mangement, there were no errors. Once installed the fan control button does not work, but it alternates/changes brightness of the button between low and high brightness (just the button, not the LCD screen).
If I play a game, the performance is terrible. I can hear the fan, an it's running slowly. On Windows 7 it was much louder and putting out much more heat and air. Also, CPU usuage is only at 10% while playing Starcraft 2 in Windows 8. This is probably why it runs pretty bad, because the CPU is being throttled.
Some good news, I installed the Windows 7 version as the previous poster suggested, and it worked. My fan control button works fine now and my games are running great again. It's amazing the effects a "energy management" software can have on this computer.
Keep us posted on the Win8 version of the application.

I used a windows 8 upgrade and had the same issue. I uninstalled the windows 8 energy management software and installed the windows 7 software. The energy management control button worked adn i was able to enabled the "efficient thermal dissapation" setting.
After I restarted, however, the button no longer works, despite the fact that I'm using windows 7 software.
