  1. 20H1 Sleepstudy report does not show modern standby


    I have a few laptops that support modern/connected standby S0 Low Power Idle but after upgrading them to 20H1 OS Build 19041 I realised that the sleepstudy report no longer shows connected standby but instead it shows sleep instead. I need the sleepstudy report to analyse the HW/SW DRIPS for the various components I’m using.


    Can I ask whether is this a known issue or has anyone else been able to find a workaround for this issue whereby I’m able to analyse the sleepstudy report for modern standby on 20H1 platform?

    :)

  2. Is there any OS function that let us check system is going to enter modern standby?

    Hi,



    Thank you for writing to Microsoft Community Forums.



    Windows 10 Modern Standby (Modern Standby) expands the Windows 8.1 Connected Standby power model. Connected Standby, and consequently Modern Standby, enable an instant on / instant off user experience, similar to smartphone power models. Just like
    the phone, the S0 low power idle model enables the system to stay up-to-date whenever a suitable network is available.



    We would suggest you to refer these articles for additional information:

    What is Modern Standby?

    Prepare software for modern standby

    Modern standby SleepStudy



    However, as you are into software development. Let me point you in the right direction, where you would get the appropriate help for this issue. I would suggest you to post your query in
    MSDN forums, where we have experts and support professionals
    who are well equipped with the knowledge on Modern Standby to assist you with the appropriate troubleshooting steps.



    Regards,

    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...

    Lenovo C940 - Troublesome in Modern Standby Mode

    Hi all.

    Ongoing troublesome Lenovo C940 here.

    Latest primary symptoms: In modern standby mode, various background processes are incredibly active. This means, maybe 30%-50% of the time, I come back to a very warm laptop, or a hot, dead battery if it decides to do this while unplugged/in a bag.

    Investigations: My main investigative work into this problem has been SleepStudy reports. When I do come back to the computer and it's warm, I produce a sleep study report to investigate. No two occasions show the same cause of the high activity though. I've attached a few recent sleepstudy reports for someone to review and help troubleshoot. You'll note the red colour-coded Modern Standby states.

    I've already had the motherboard replaced for other waking-from-sleep problems (maybe related, maybe not); that didn't change anything.
    I repair-installed the OS, which changed the problem to primarily be high activity in Modern Standby mode, resulting in frequently recurring BSOD problems -- especially BSOD while in Modern Standby mode.
    Then I reinstalled the OS twice (reformatting both times), once using the Microsoft-sourced Windows 10 1909, and then subsequently using the Windows 10 sourced from Lenovo specifically meant for the C940. Both reinstalls resulted in the same high-activity during Modern Standby, as well as causing the fingerprint reader and webcam to stop being usable; the fingerprint and webcam just suddenly started working today though, with absolutely no change to anything, as far as I can tell...

    Therefore, just reiterating, the PRIMARY remaining problem is this high activity in modern standby. Lenovo have told me that I'm not supposed to leave a laptop in this mode unattended, and that high activity in this mode is normal; even that draining 79% of the battery in Modern Standby mode for 25 hours is fine...

    Windows Version: 10.0.18363 and just installing KB4532695 in the background.

    - - - Updated - - -

    Please, if there is anything else I can do to get some support, let me know *Confused Do you need other logs, or anything else?

    - - - Updated - - -

    Another instance, with another example of a different source of the power drain in Modern Sleep mode.

    Can anyone help? What else do I need to share?

The option isn't available anymore for my laptop. I am speaking about this option: https://i.imgur.com/jD6odQx.png...
