    Waking From Sleep ? ? ?


    I had this same problem while running under Win 7, and now under Win 8.1 Pro my PC is doing the same thing. It seems to wake up all on its own from "Sleep". I went through the device manager and looked at everything, and nothing but my KB and mouse where set to "Allow this device to wake computer". I set KB to disallow to wake PC, and left just my mouse.

    Mobo is an Asus Sabertooth X79

    I tried to use this command from both the Admin Command Prompt and PowerShell but basically am told its not a valid command... powercfg –devicequery wake_armed, even though this very command is posted on Ms own tech site for commands.

    I used "powercfg -lastwake" which resulted in...

    I would try making the keyboard the only device that is allowed to wake the computer. Because your mouse works by detecting motion, it is far more likely to send a false signal and wake up the computer than your keyboard.

    That seems to have fixed the problem, but now the stupid thing won't go to sleep on its own when it hits the set time of 1 hour, I have to manually put it to sleep every time. I've even went throughthe task manager and killed anything that might be keeping the desktop active
