    Computer Sleeps/Wakes fine manually, but won't wake from auto-sleep


    Hello,

    My motherboard is a P8Z77-V, with Gigabyte 7950 video card, if that matters.

    I did the windows 10 upgrade, and all seems well, except waking from Standby.

    If I go into start menu, and choose sleep, everything spins down, and the computer shuts itself off. I am assuming this 'sleep' is some sort of hibernate. Great, love it.

    But when I leave the computer over night I come back and the monitors are off,but lights on tower on. I am assuming this is standby mode? Anyway, I can't wake the computer from it, using mouse or keyboard (both USB). Clicking power button on tower does nothing. I generally have to click the reset button on tower and do a full boot sequence. When I log in, I do not get a message about windows not shutting down properly (maybe that message is no more in 10?), but clearly it is a fresh desktop.

    I reset all bios settings, and update to most recent bios. I have the latest graphics drivers.

    This is driving me nuts! Suggestions or trouble shooting tips?

    Here is some investigating I did, hopefully it helps:
    Code:
    D:\Users\Shea.Wilbur>powercfg /a
    The following sleep states are available on this system:
        Standby (S3)
        Hibernate
        Hybrid Sleep
        Fast Startup
    
    
    The following sleep states are not available on this system:
        Standby (S1)
            The system firmware does not support this standby state.
    
    
        Standby (S2)
            The system firmware does not support this standby state.
    
    
        Standby (S0 Low Power Idle)
            The system firmware does not support this standby state.
    Code:
    C:\WINDOWS\system32>powercfg /sleepstudy
    S0 Low Power Idle is not supported on this machine. Cannot run tool.\
    Anything else to try? BIOS settings to check?
