    Can't enable Modern Standby


    Does anyone know how to enable Modern Standby on the Maximus XI motherboards?

    They use the Z390 chipset that is suppose to allow Modern Standby on a Windows 10 desktop, but I'll be darn if I can figure out how to enable it.

    I still get this:

    I don't if this is relevant, but the page on "Modern Standy" says "You cannot switch between S3 and Modern Standby by changing a setting in the BIOS. Switching the power model is not supported in Windows without a complete OS re-install"

    Totally different box and MB, get same/similar. Don't think I've ever been able to get S0.

    (I have hiberfile.sys disabled)

    I wasn't sure if the info there was still relevant or not either with it being over a year old, but I clean installed Windows 10 anyway to test. Same results though.

    This is what I could find in the UEFI firmware settings that seem related.

    Hi,
    What are the options under power loss besides shutdown
    Does anything else change or more options show up if switched something else ?

    Here's the options for "Restore AC Power Loss".

    Both "Power On By PCI-E" and "Power On By RTC" just have Enabled or Disabled as options.
