I am also having this issue in Windows 10. The laptop screen goes blank like its sleeping but then nothing can wake it. The power button light is solid which I think indicates sleep and not hibernation. In order to get the system back I need to hold down the power button to shut it completely off and then back on again. To me this is a really annoying and I’m about to return the system. I am coming from a apple Macbook which has worked pretty flawlessly for about 5 years and I has high hopes for the framework. I’ll keep an eye on this thread but if It can’ be solved soon it’s going back.
