good old registry hack does not work anymore:

  1. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power] CsEnabled=0
  2. deleted [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\ModernSleep]

PC still uses "Standby (S0 Low Power Idle) Network Connected" and it makes a lot of problems

    Hi All,

    Right after getting the 20H2 update installed S0i3 seems to be back even with this one in registry:

    reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0

    That's despite my machine isn't even advertising S0i3 support - only S3:

    C:\WINDOWS\system32>powercfg /a

    The following sleep states are available on this system:

    Standby (S3)

    Hibernate

    Hybrid Sleep

    Fast Startup

    The following sleep states are not available on this system:

    Standby (S1)

    The system firmware does not support this standby state.

    Standby (S2)

    The system firmware does not support this standby state.

    Standby (S0 Low Power Idle)

    The system firmware does not support this standby state.

    C:\WINDOWS\system32>

    Is W10 with 20H2 update enforcing S0i3 thereby ignoring the fact it's not supported then? How do I disable it again anyway? I have reasons not to ever have it enabled in my particular application, even at the expense of having no Standby whatsoever (I'll have to use Hibernate instead in the worst case, as I already did before). 

    Many thanks in advance!

    Update: Sorry looks like I just forgot to manually put it into the (S3) sleep, so it may have just turned off the screen while staying active all the time as per my Standby timeout settings and so was warm to touch.

    I didnt understand if your reply has any connection with my post and if your post was translated by computer like google.

    But I am using 20H2 too, and i cannot use S3, as bad as before.

    I dont like SSD so i dont want to use S4, and i want my battery more useful so i dont like S0.

    Is here any one can help me crack EFI files or BIOS to enforce use S3 mode?

    Or is someone strong enough to kick DELL's **** to let them support S3?

    I am very sure that my hardware supports S3 and my BIOS and EFI not.

    My XPS 13 can switch to S3 and could sleep normally. But after wake up, NETWORK IS NOT WORKING and wireless module cannot be found in System Device Manager.

    Any solution for this plz?

    龙缘科技神林: Sorry just noticed your message. As a lucky owner of a Lenovo ThinkPad X1G6 all I had to do was switch the toggle in its BIOS to the mode that means S3. The reason for posting my message above was that I initially thought by mistake that it's no longer working with 20H2... can now confirm it's been sleeping deep perfectly fine with S3, same as 20H1.

    You are so lucky. Unfortunately, My BIOS doesn't provides S3 option toggle. I use DELL INS 7400 1825HS.
