So as of 21h1, you have to go into the registry
Code Select
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes
Right-click the PowerSchemes folder, select properties, and then advanced. Change the owner to your profile like you would on a normal folder, and then add your security principle to the list with full control. Check the box under to replace the ownership of object under this folder. Click apply. Close both advanced and the properties. Look through the list of subfolders for the plan you want, in my case thats Ultimate. Copy the name of the subfolder. This should be a string of numbers and letters. Then open up an admin powershell and enter
Code Select
powercfg /setactive [i]pasteNameOfSubfolderHere[/i] Press enter. Then enter in
Code Select
powercfg /list to verify that your wanted scheme is active with a * at the end of the entry. Dont worry, the ownership will be put back to system for that folder on the next reboot.

God bless the person that found this fix. The Microsoft team in charge of the idea behind Modern Standby without giving the option to disable it should be fired.

I got a new X13 AMD and lo and behold - Turn on HyperV platform for Docker and WSL2, and suddenly, "Hybrid Sleep S3" is disabled because "Hypervisor does not support this"

Solution: In BIOS, there is a setting "Sleep State", with the two options "Linux" and "Windows". My hunch was that this was the toggle between classic S3 Standby and Modern Standby. It was.

Switch to Linux and suddenly, i got good old reliable S3 in Windows back, while HyperV is running.

This worked for me as well on a T14, thank you!

this version of the registry hack worked for me on this Dell G15 (i7, NVIDIA). it disables the last sleep state willing, the crap S0, leaving windows no choice but a full hibernate. sucks arse, but its better than melting itself in my backpack.

i don't want to suggest the moron that made these choices be introduced to a woodchipper, but, if i heard of it happening i would be like "they earned it"

I also want to add to the list LG Gram 16" 2021 .

It was driving me crazy!!!

Battery drainage , unwanted CPU usage ( thus system heating up ) and generally not what I used to know what suspend / sleep is, from my older machines. I paid 1370 euros and I thought that my machine was broken before I find out after hours of reading and searching that this is a "modern" sleep!

No go for me at all. I hate it , I do not want it and thank God I found a DELL forum with other people having the same issues .

Also there is a fix in one of their posts that I applied and after some tests, on my one month old laptop , it seems that it works now like it should! This fix is more or less what fluXion posted here!

This should be escalated in tech news...

It should be optional , not shoving us "features" down our throat.

Thank you.

The original registry hack no longer works, but this registry hack did. Run the following in cmd.exe running as administrator, or use regedit to do the same thing.

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

Thank you a lot man. This worked for me as well.

On AMD Ryzen 5000 systems, even this tweak, PlatformAoAcOverride, doesn't work for 20H2/21H1. They truly removed, broke and crippled S3 standby (some UEFI BIOSs do not even implement S3 any more) and S0 state is HORRIBLE.

Very appreciate for last update. My Asus Rog GX 502 LWS get this problem at the beginning and I don't use sleep mode at all, after few overheating and BSODs. And now after check in power shell by "powercfg /a" there is no any more sleeping mode S0, know appear S3. I use last update of windows 10 20H2 19042.928
So this key is really working HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0
Thanks a lot

How do I re-enable Modern Standby after disabling it? I tried changing the last digit of the registry file to 1 but it didn't work. Command Prompt still reports S3 as enabled and that S0 aka Modern Standby is not supported by the system. Please help.

It looks like Microsoft has a fix on the way. Windows 10 20H2, which, despite the name October 2020, will likely reach us in November.

I have exactly the same problem, of course with DELL - all other notebooks I use (HP, Lenovo, Asus) do NOT have such problem. I've spent a few days now and lost a lot of time and nerves - it just sucks, after the latest Win10 update, the bloody DELL precision cannot sleep, as of the idiotic "Standby (S0 Low Power Idle) Network Connected" and "Standby (S3) This standby state is disabled when S0 low power idle is supported." The only solution: I'll never buy another DELL again. "S0" should be called "DELL Insomnia" really, as it keeps the notebook running, going overheated and draining the battery empty - it's pretty dangerous if this happens in a closed backback, it could burn as it's overheated as hell in the sommer.

Good lord, I never thought someone else would have the same experience as me! My laptop rarely ever goes to sleep properly. It's supposed to go to sleep, and then hibernate after a certain amount of time  has elapsed. And so everytime I leave my laptop I have to remember to hibernate it. I'm only human though so I might forget to hibernate it or I might think that I won't be gone for long.

And you know what happens to this Dell Inspiron laptop when it doesn't sleep? A BSOD! Power state failure. And to think that Windows 10 version 2004 started this. This has been happening to me at least once a month this year (when I got this laptop). Only today when it happened again did I actually go into event viewer. I found some error to do with modern standby. I Googled a few queries and landed here. I don't know who to blame, Dell or Microsoft. I'm just frustrated.
