    Mike,

    I do not know why you are not getting events recorded when they seem to have taken place.

    Perhaps, if you wait, Ken will chip in after he has resumed from sleep.

    Cool, I'll be patient :)

    I'd just note the odd situation re: Connected/Disconnected Standby. powercfg -a suggests Connected standby is activated. Referring to the options in the Tutorial you sent:
    Option 1: Indeed, the setting is set to Always disconnect WiFi.
    Option 2: This setting is not visible in my Power Options > Advanced Settings
    Option 3/Option 5: I might pursue these, but I've tried RegEdits like Option 5 before, and it caused serious problems like overheating while supposedly turned off, therefore I'm hesitant. I feel like I shouldn't have to resort to these measures though -- shouldn't Option 1 or 2 work?
    Option 4 is not possible (Windows 10 Home)

    Mike,

    Can I just check your objective regarding Connected/Disconnected Standby?
    Remember to regard ModernStandby as just meaning something similar to WhenIdle.

    #1 When your monitor turns off [as set in your Power options], you want your computer to disconnect from your network / the internet?
    or
    #2 Despite your monitor turning off [as set in your Power options], you want your computer to remain connected to your network / the internet [assuming it was connected in the first place]?

    Yours is currently set as #2. I had to use the PowerCfg commands in Option 3 of the tutorial to set mine this way because mine's default setting was #1 & the only practicable alternative was to keep the monitor on the whole time if I wanted to get emails while the screen was off.

    About tutorial Option 2 - at the end of the tutorial there is a list of related tutorials. One of them is
    Add or Remove Networking connectivity in Standby from Power Options - TenForumsTutorials
    but you might lose all interest in that if your answer above is #2.

    Hmm, I'll try to outline my thought process here, referring to the settings I showed in the original posts, for the Plugged In state:

    I let the screen turn off after 15 minutes idle. I don't care if the network is connected or disconnected in this case.

    After 30 minutes idle (I guess this means 15 minutes after the screen turns off), the computer goes to "Sleep" (or, as we are discussing, it goes into Modern Standby mode). In this case, I think my preference is that no network connectivity should be allowed. I prefer this because I am suspicious of background processes like Windows Update or other things working to keep the computer from going to the next state:

    After 120 minutes idle (I guess this means 90min after entering Modern Standby -- and perhaps this answers the 90minute question in my original post), the computer Hibernates. In this case, there should DEFINITELY not be any network connectivity.

    It's the intermediate state that's problematic, apparently. Despite the Network connection setting set to Always disconnect from the network, the powercfg -a output shows Connected Standby is enabled. So my objective regarding connect/disconnected standby is to fix this, as I am suspicious it is part of the problem whereby my computer turned itself on and stayed in Modern Standby for 18 hours.

    Mike,

    So use the PowerCfg commands in Option 3 of the tutorial to achieve what I referred to in my para #1 - you want the network to disconnect when the monitor goes off
    Enable or Disable Network Connectivity in Modern Standby - TenForumsTutorials

    Code:
    powercfg /setdcvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0
    powercfg /setacvalueindex scheme_current sub_none F15576E8-98B7-4186-B944-EAFA664402D9 0

    and then, for convenience, consider
    Add or Remove Networking connectivity in Standby from Power Options - TenForumsTutorials

    I think that would be a useful time to review the situation to identify remaining issues [because I'm confused about what remains].

    Do bear in mind that WU can jolt it out of ModernStandby if it wants to check for updates.

    Best of luck,

    Thanks Denis, I'll give that a try and report back regarding connected standby. Sadly, I find it can take several days to confirm. Possibly, if it is WU or some similar scheduled thing, it can take up to a week to recur?

    The remaining issue will just be if the laptop does something like what instigated the original post again (that is, Shutdown, turn itself on, "Sleep", and drain the battery in 18h --- which, even on Modern Standby with Network Connection, is an extreme thing). 8 months on from my very first Lenovo C940 / Windows 10 modern standby problems, and now on my second C940 laptop, I am not optimistic that we won't see the same symptoms again

    Mike,

    You do not have S3 so you do not have Sleep because S3 is what we normally mean when we say Sleep. There is no point having any references to sleep in your power options because you do not have Sleep.

    The battery drain that you comment on is a drain occuring while the computer is switched on, albeit with ModernStandby [i.e. an overhyped idle condition] taking place. So your computer is so efficient that it lasts 18 hours while switched on. That is impressive.

    Please remove all references to 'sleep' from your thinking and then state what remaining issues you are concerned about.
    - You do not have S3 [i.e. Sleep]
    - ModernStandby is an overhyped idle condition. It is not Sleep.

    Apologies, I do understand. When I say "Sleep" in quotations, I recognize that it's modern standby and not traditional Sleep mode. I say "Sleep" because that reflects the text in the settings dialogues (although not behind the scenes, in things like sleep-study report, I recognize).

    So I will implement the changes and give it some time to be observed, and see how I would describe any unfortunate behaviour that continues.

    For now, I can only agree with what you've said already: The lack of a proper / traditional Sleep state, as an intermediate state between Hibernate and fully awake, is frustrating. I can only hope that frequent hibernations and waking from that hibernation state, are not otherwise damaging...

    Mike,

    "Sleep", in things like your Power options, is indeed misleading, as you say.
    1 You can use the Power options, Choose what the buttons do dialog to remove Sleep from your Power menu
    2 You can use the Power options, Choose what the buttons do, When I press the power button to Do nothing, Hibernate or Shutdown.
    3 You can use the Power options, Choose what the buttons do, When I press the sleep button to Do nothing or Hibernate.
    4 You can use the Power options, Choose what the buttons do, When I close the lid to Do nothing, Hibernate or Shutdown.
    5 Then you can select your power plan itself and set Put the computer to sleep to Never [because it cannot do it so having anything set there is just going to confuse the picture].
    6 Then you can go into the the Advanced power settings dialog and set the time delays for Hibernate after [which happens to be in the section labelled Sleep]
    These utilities were designed for WinXP and earlier and they don't really understand ModernStandby.

    Using Hibernation does not damage anything.

    I agree that the lack of Sleep is frustrating. I checked on an older computer a while ago and it used only 1% of its battery power an hour on Sleep [S3] so I could, for all practicable purposes, have my computer available for immediate use for days without plugging it in. Since waking up only takes 1 or 2 seconds, I regard its Sleep state as being immediately available.

    There used to be a method for suppressing ModernStandby and enabling Sleep [S3] but it stopped working / working reliably at Version 1903. There is one claimed solution [a custom third-party utility] but it only works with Intel processors which my ModernStandby computer does not have.
    - There might be other limitations that I am not aware of.
    - The issue is discussed in v.2004 update removes ability to turn off "Modern Standby" - TenForums
    - The TenForums user Ander was very informative.
    - The TenForums user gorgor who jumps in on that thread turned out, or so it seemed, to be the author of that custom utility
    - This is not a recommendation. I am not aware that there has been any validation of that utility.
    - As you'll see in that thread, I was rather taken aback by the inability of the utility's apparent author to state a set of system requirements for it.

    Great discussion.

    Your listing of available sleep states does not included S4 which is the traditional "Hibernation" state so I wonder what hibernation is actually taking place when report list hibernation.


    What time do you have Windows Maintenance set to?


    Haven't work on any devices with Modern Standby so just asking, is this something you can disable in BIOS and return to the more traditional S3/S4 states?


    Under Settings > Privacy > background Apps ... what apps are allowed to run in Background?

    Mike,
    I forgot to add an xml for Event viewer monitoring ModernStandby transitions
    Power - S0 transitions.zip
    Ere tis,
