Y470 Slow/Stuttering when Gaming - Windows 8... Was fine in Windows 7

2012-11-11, 3:40 AM

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.

 

Thoughts?

Solved! See the solution

If you want to clean the fan you could do it manually

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.

If thats the case, then use the energy management for windows 7. The one for windows 8 isnt a good idea. No compatibility issue. You should hope that lenovo release for windows 8

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.

Hi all,

 

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.

 

Regards

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.

 

Thanks.

Chris

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.

Hi ondax1,

 

Thanks for posting your concerns. I was just wondering if you have tried installing the Win7 Power management instead. Some of the models that have been upgraded to win8 did report some issues with the WIN8 powermanagement. So what they did was to install the Win7 Powermanagement instead.

 

The link to download the Powermanagement can be found below.

Please do give that a try and let me know of the results.

 

Regards

Hi Nine,

 

I'm currently owning a Y470 and i just updated to window 8.  The performance when i'm playing game in Window 8 is terrible and my guess is that it's using the intel HD graphic instead of using the Radeon HD 7670M whenever i'm playing game.  Is there anyway to fix this?  The catalysy center program show a log that tell me to updgrade my AMD driver as it's imcompattible.  Where can i download this driver ? Or is there anyway to fix the bad performces when i'm playing games. 

 

Thank you

Yeah, I also have a problem with my Y470p only using the Intel 3000 chip, and not the 7690m. Also, WIndows is detecting my 7690m as a 7670. Any help?

Hi all,

 

After checking with the teams, you may want try uninstalling the Win9 Energy Management software and try running without the energy management and check for the changes. The machine is capable to run the without the energy managent as the Win8 is also optimzed to rin the Lenovo machine without the Energy management. Please do Give that a try and let me know of the changes.

Windows 8 nor 7 are not optimized to run the Lenovo Y470 without the energy management software. From my observation, it's easy to see that the thermal management controls the BIOS when dual booting Windows 7 and 8. When I select "super silent" in Windows 7 then boot to Windows 8, the fan control button still blinks in Windows 8 and the fan does not spin as fast unless I go back to Windows 7 and set the thermal management to "efficient dissipation mode" then boot again to Windows 8. (Note that I did not install the thermal management software in Windows 8 since it does not work). To resolve this issue, I just run Windows 8 in a virtual machine using VMware Player since I only use the Metro apps in Windows 8 and keep all my x86-64 programs in Windows 7.
