[rMBP] No Sleep Mode in Bootcamp

[Septic]

Hello,

I noticed that starting with the PowerNap Update the Sleep Mode stopped working!

powercfg -a Output:

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 (S3)
        The system firmware does not support this standby state.

    Hibernate
        An internal system component has disabled hibernation.
                Windows To Go

    Standby (Connected)
        The system firmware does not support this standby state.

    Hybrid Sleep
        Standby (S3) is not available.
        Hibernation is not available.

    Fast Startup
        Hibernation is not available.

Somebody else noticed this too?

There are already a few threads on the Apple Communities, but the issue seems to be not beeing discussed

Do you have a thunderbolt device plugged in?

 

[Septic]

Yes I have the Ethernet Adapter


Removed it, now there's sleep

Why is that happening?? Windows Driver Issues or does the EFI disable Sleep if there's a Thunderbolt Device?

Probably, the thunderbolt adapter is thinking its connecting to a display not ethernet, but thats just my predictition.

Why shouldn't it allow standby if it was connected to a display?!

I think it has something to do with the missing plug-and-play support for thunderbolt - probably Apple disabled the sleep mode for Bootcamp if a thunderbolt device is attached at startup - at least it feels like that
