Windows 10: Scheduled wake from DRIPs (Modern Standby)

So, I've spent the last week scouring the web for this and failed!

I am trying to wake a Dell XPS laptop overnight to run maintenance tasks, including backup to local network server, and so far it has proven impossible.

While in the "Resiliency Phase" (https://docs.microsoft.com/en-us/win...modern-standby) all apps run in an Interactive Session are suspended but task running In Session-0 appear able to run. However, once the computer has entered DRIPS any task that relies on sleeping hardware will not succeed and on the Dell XPS, which runs in "Standby (S0 Low Power Idle) Network Disconnected", this includes the network adaptors (both WiFi and USB connected Ethernet), so even backup tasks that I can get to run still fail due to no network connection. Waking from DRIPS on a schedule seems impossible!

Wake timers do not work on Modern Standby systems, so neither do any user created Task Scheduler tasks (even ones set to run under SYSTEM). About the only thing that will occasionally wake the system is Windows Update, but it seems there is no longer any way to schedule that. Microsoft docs say UWP apps can (https://docs.microsoft.com/en-us/win...y-wake-sources) but it seems no one has written one for this purpose.

Surely there must be a way, short of writing your own UWP app, to get a Modern Standby system to wake from DRIPS out-of-hours for housekeeping?? There don't seem to be any code snippets we can use. This just seems crazy hard!

All that needs to happen is for the software equivalent of a "power button press" or even, I think, just the computer to leave DRIPS. The tasks are waiting to run and as soon as the system wakes they should keep the system awake until they have completed.

Hopefully someone can make me look a total fool and point out something I have missed!

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.

 

Task Scheduler not compatible with Connected Standby

Just so you will know... With Windows 10 on the Surface tablets, Task Scheduler cannot wake the device to perform a task. Task Scheduler is incompatible with Connected Standby. Unbelievable...

 

Best Buy says all Windows 10 PC support Modern Standby now, Is this true ?
