Adjust Hybrid SLI Settings Under Power Options on Windows 7
I was working on my new laptop and have been having some crashes. After analyzing some of the dump files I determined that I was having some video driver issues. When I first got the laptop I remember setting the hybrid sli mode to high performance. After deciding I should probably switch this setting back to the default mode I was not able to find the option to switch it back. I couldn’t remember how I set it in the first place so I did a little googling and it told me there should be a GPU section under the advanced section of power settings.
Well when I looked at my power settings I could not find the GPU options. I knew I had set this up somehow but since I found a lot information about how the GPU was supposed to be under the power settings, I decided to embark on the quest to figure it out.
Turns out its disabled by default in Windows 7 for some reason. I wont speculate as to why but I wanted mine back. Generally when some thing that used to exist disappears, I look in the registry to see if its been simply disabled.
I found the setting and low and behold one of the values was HidePowerSetting and it was set to 1 which is true. I changed it to a 0 and it gave me the GPU settings I was looking for.
Here’s how I did it:
- Open Regedit by typing it in the search bar.
- Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\Hybrid
- Change the entry HidePowerSetting so that it’s value is 0
- Restart your computer
Once you do that you can open up your power settings and adjust the settings.
To find your power settings:
- Open the control panel
- Locate and open power options
- Select change plan settings for whichever plan you are using currently.
- Select change advanced power settings
- Scroll down till you see GPU and change your settings
I’m sure there is another way but I like to find hidden settings and enable them so this hack was a win.
