Windows 10: Windows 10 Crashing in Modern Standby

As the title says, I've found from a SleepStudy report produced using Windows Powercfg that my computer is often crashing when it goes into Modern Standby -- generally for periods of longer than an hour. This has happened 3 times in the past 4 days. I think it has something to do with another problem I'm having where the computer won't wake from Modern Standby sometimes -- but that's an aside. Let's just focus on finding out why it's crashing when it should otherwise be asleep and idle.


I've already run the analysis on the Minidump files, but I'll provide everything here for someone to look into. Note that all three dumps point to different causes I think. But maybe there's a common theme I don't understand.


This is on a Lenovo C940 laptop. Lenovo's full memory test has suggested no memory problems, but I'm open to suggestions for other memory tests...

Can't enable Modern Standby

You need an exclusively UEFI PC (without Legacy support) for Modern/Connected, at least it's what I've heard. I guess if that Z390 doesn't have it, I am not really expecting any consumer desktops to implement it, I assume it would require manufacturers to kinda rewrite their BIOS. It is also indirectly suggested on Anandtech that the feature depends on the onboard WiFi:

Personally I love my Ethernet cables and 1Gbit speeds, and WiFi would be the last thing I'd do to my PC, but I would like to test this feature when I buy a new PC, since Z370 is clearly out of question. Considering that Z390 basically has onboard WiFi and Z370 doesn't , it further solidifies this as a potential WiFi only feature. Maybe it's possible for the PC to switch to WiFi for Connected Standby and then back to wire after it wakes up? That would be nice.

Edit: there's also this:
"Modern Standby is only available on some SoC systems. When it's supported, the system does not support S1-S3."

Yeah... S3 is the "normal" standby. So if your firmware manufacturer supports that, it's bye-bye Modern? Ouch.

 

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:

Can't enable Modern Standby

Are you specs up to date Shawn?
A 8700K with a Z390?

You might need a 9th gen chip to use the modern standby, or not?

Note

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.
