    NohwdripsC10 is never turns off in modern standby and consuming battery during sleep


    Modern Standby is a very good feature in Windows 10. But when i watch sleep pattern by using command powercfg -sleepstudy then the report says NohwdripsC10 always run and it never turns off no matter how long i leave it in sleep mode. The colour of that layer is always red in sleepstudy report. It drains battery much. Red in sleepstudy means something is consuming my battery. How to diagnostic that.

    Nvidia dGPU blocks modern standby on laptop

    @gorgor, I finally had some time (and spare NVMe) to reinstall Windows 10 2004 on my XPS 9570. I installed Dell Command | Update application after installing Windows and used the option to reinstall all the drivers. After that I ran a regular check for updates in Dell Command | Update and it had about 6 more updates to install, at which point I did that.

    In the mean time I found this article from Dell ( https://www.dell.com/support/article...havior?lang=en ) that outlines some settings to change and drivers to install in specific orders to improve the sleep. I did not install their Modern Standby Performance Improvement Package Application as they suggest since they say it only automates some of the instructions they give.

    After all that, the first overnight sleep only used 7% battery with SW and HW in low power state 100% of the time!

    One thing to note, the dell site says to change to Disconnected Standby but doesn't tell you how. Here are the commands I ran for that (taken from Enable or Disable Network Connectivity in Standby In Windows 10 ):

    Disable while in standby on battery: powercfg /setdcvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0

    Disable while in standby plugged in: powercfg /setacvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0

    I have not tried performing these steps on my previous install. I did a full re-install because Microsoft specifically states that you cannot switch from S0 to S3 sleep without reinstalling the OS. I figured you probably couldn't go the other way around either.

    I'd be curious if the steps outlined on the Dell page solves your issues. I don't have my hopes too far up as I feel like I've had similar results before but it eventually stopped sleeping so well and I had no idea why.

    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.

    NohwdripsC10 is never turns off in modern standby and consuming battery during sleep

    Which Laptops support Modern Standby ?

    Neither Dell or Microsoft make known which systems are Modern Standby capable. The chances of a 2-in-1 system being modern standby is very high.

    For Dell, many of the 13 inch models do standby. I do not yet know if the XPS 9575 does because nothing in the specifications will show that capability.

    Just so you know, many folks freak out when they see the battery drain when they think the system is sleeping.
