    Screensaver and power settings are not working in Win 8.1


    Hi everyone,

    My screensaver and power setting to turn off the display has stopped working, and these were working the other day. The only thing I have changed is I updated iTunes. I have tried a system restore to before this and this did not fix this.

    Among other things I have tried a clean boot, sfc, and checking the energy report. Clean boot did nothing and sfc gave no errors. I uploaded my energy report if any one thinks it could be useful.

    I also tried to put the PC into sleep, which I don't normally do and it woke up a little while later. That gave me the following error in event viewer:

    The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S4). This can result in reduced resume performance.
    I tried searching around for additional tips but could not find anything helpful. Can anyone help me figure what is causing this?

    I actually don't have that installed. The lowest my updates go down to is KB288

    Interesting, I figured it out. My Wii U Pro controller was the problem, and when unplugged it is fine. The problem didn't exist a couple days ago though so I'm not sure why it is happening now.

    Possible a compatibility problem that has now surfaced.

    As long as you have partially fixed the problem, Great.
    This may help others.
