System Disable Modern Standby in Windows 10 and Windows 11


  • Staff
Power_banner.png

In Windows 10 and Windows 11, there are two power models for PCs: S3 and Modern Standby (S0 Low Power Idle). The S3 power model is an older standard and is not capable of the instant on that consumers expect from modern devices. Modern Standby is capable of leveraging all the capabilities of a modern chipset and can be integrated across the breadth of tablets and PCs today. The first iteration of Modern Standby was Connected Standby, which first shipped in Windows 8 and Windows 8.1. Modern Standby expands upon the Windows 8.x Connected Standby concept, allowing for flexibility in component selection and the ability for the OS to manage network connectivity in standby.

Windows 10 and Windows 11 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 connected to the network while in a low power mode.

Although Modern Standby enables an instant on/off user experience like Connected Standby, Modern Standby is more inclusive than the Windows 8.1 Connected Standby power model. Modern Standby allows for market segments previously limited to the Traditional Sleep (S3) power model to take advantage of the low power idle model. Example systems include systems based on rotational media and hybrid media (for example, SSD + HDD or SSHD) and/or a NIC that doesn’t support all of the prior requirements for Connected Standby.

Modern Standby systems can be connected (enabled), disconnected (disabled), or managed by Windows to allow network connectivity during standby. This behavior is dictated by the hardware and/or by configuration.
  • Connected Modern Standby will allow you to stay connected to the network while in standby to still receive and get notifications about email, VoIP calls, and such, but it will use more battery.
  • Disconnected Modern Standby will allow longer battery life, but you will no longer have the advantages of staying connected to the network while in standby.
  • Managed by Windows will allow Windows to manage network connectivity during standby.
On any Modern Standby system (whether connected or disconnected), the system remains in S0 while in standby, allowing the following scenarios to work:
  • Background activity
  • Faster resume from a low power state
On systems that are connected while in standby, wakes based on specific network patterns may also be set by the operating system to enable apps to receive the latest content such as incoming email, VoIP calls, or news articles.

See also:
This tutorial will show you how to disable Modern Standby (S0 Low Power Idle) to enable S3 support on a Windows 10 and Windows 11 device.


If you disabled Modern Standby and your PC crashes when entering S3, you can press and hold the power button to force a hard shut down, press the power button again to turn on, and enable Modern Standby again.

This can happen if the OEM has removed S3 from the BIOS/UEFI.


You must be signed in as an administrator to enable or disable Modern Standby.

You cannot enable Modern Standby on a device that didn't originally support it.

Thanks for all your great articles on Connected and Modern Standby. Been very informative lately, I guess I lost track of developments after the Connected Standby days.

I'm going out of my mind trying to figure out why my PC fan loves to blow when I think it should be asleep. It's intermittent and I've never found any process consuming a great amount of CPU, it'll just blow and then get quiet continuously every 10 minutes while it's asleep.

After a ton of headscratching and trying to disable wake timers and such, I noticed that powercfg /lastwake was always "wake count=zero", and further observed that the laptop power light did not flash when I put it to sleep mode. Then I thought "maybe it's using the old Away mode" so it can serve up network shares or shared media, but that wasn't it either.

Apparently my system is never actually sleeping and remaining in S0.

I wouldn't care if it would just be quiet. And what's really weird is it WILL be quiet if I disable all power saving options. If my screen is on and sitting at the desktop with no programs running, it will be silent forever. But the moment my screen turns off, the fan starts blowing loud. Then it stops when I wake it back up (or at least make the screen come back on).

I'm about to go reboot into bios options and see what I can do there, might be worth a reinstall, I was going to try out the new smart app control anyway so two birds and all.

@CmdrKeene You are not alone. IMO modern standby is a nightmare for some laptop users. There are quite a few threads in this forum about it relating to issues such as overheating, loss of internet connection, and battery drain. It might be beneficial to you to read them. If after trying some of the suggestions you still can't tame your laptop, start a thread in the forum section and members will do what we can to help you. Chances are, your new Dell will not support S3 sleep. The general consensus is, about the only thing one can do with a modern standby laptop when it's is not in use is to turn it off or put it in hibernate. And NEVER carry it in a case unless it's off unless you want it to fry.

Correct, if you have S0 then you do not have S3 Sleep.
- I adapted to S0 by using hibernation when I had been used to using S3 Sleep.
- When I got even more fed up with S0, I set my monitor to always stay on [it's the monitor turning off, as set in Power options, that starts S0] and I set a very dark screensaver to come on after a desired time so the screen wouldn't be staring at me all day.
- Eventually, I just used this tutorial to disable S0.
- - In my case, S3 Sleep remained disabled so I carried on having to use hibernation as a second-best choice.​
- - In my case, Task scheduler would not wake the computer from hibernation but others have reported that theirs worked OK.​
- - In my case, my WiFi adapter often fails to restart properly [no networks detected] when it comes out of hibernation so I run a little script to disable it then re-enable it after which it works again.​

I feel like when I first got this laptop, it would use S3. I could be mis-remembering so I'm not 100% certain, but I feel like I used to witness the power light flashing when sleeping, now it just says "on" all the time. From the articles I've read, I need to clean-install to reconfigure the system to use other sleep modes, I'm not sure if I'm ready to take that step although I'm not hard against it.

Some people find that disabling S0 enables S3. You might be one of them. It is a quick & simple procedure and equally quick & simple to reverse.

By the way, I've also seen the comment, "clean-install to reconfigure the system to use other sleep modes" but I've never seen it explained.
- Surely clean installing would just leave you back where you are now labouring under the curse of S0.
- I suspect that the comment might be a mis-transfer of something that made sense in the context of some MS dev papers about S0 definitions & hardware requirements.

All the best,
Denis

Hello Shawn, :)

So far, I've not needed to clean install windows to disable Modern Standby to use S3 with the method in this tutorial.

I ended up liking Modern Standby better though. If you're having issues with power, you could test disabling network connectivity while in standby below to see if that may help.

Brink,

Sorry, I don't get it.
In what way does clean installing then using this tutorial method differ from using this tutorial method without clean installing?

All the best,
Denis

It was mentioned in older Microsoft reference material that a restart was required, but it's not related to the method in this tutorial.

I've found a couple of references to the subject in my pile of papers.
What is Modern Standby - MSDocs
What is Modern Standby - MSDocs said:
Switching between S3 and Modern Standby cannot be done by changing a setting in the BIOS. Switching the power model is not supported in Windows without a complete OS re-install.
Modern Standby FAQs - MSDocs
Modern Standby FAQs - MSDocs said:
Q: Can I switch between S3 and Modern Standby by changing a setting in the BIOS?
A: No, switching the power model is not supported in Windows without a complete OS re-install.

Both statements are more unequivocal than I had remembered.
But, as some posts in TenForums & ElevenForum threads demonstrate, they are not universally applicable. Some people have posted that they used this tutorial's method of switching off S0 and found S3 to be enabled afterwards.
I wasn't one of them unfortunately.
But I can quite believe that replacing ACPI firmware intended to support only S0 with one intended to support only S3 might well require a clean install to have an effect.

All the best,
Denis

I have a Lenovo M90n-1 with Modern Standby (S0). Like CmdrKeene, when my pc went to sleep, intermittently the fan would run high speed for a while. I thought it was Windows Defender doing a scan but it wasn't. I disabled the "Network Connectivity" during Modern Standby but that didn't help. In the BIOS, I have the option to switch to S3 but there is the warning, "Switching between S3 and Modern Standby cannot be done by changing a setting in the BIOS. Switching the power model is not supported in Windows without a complete OS re-install."

I went ahead and added the entry to registry and after a reboot, powercfg /a shows S3 is now available and S0 is not. So far, when my device goes to sleep, the fan no longer runs at high speeds intermittently. I did not make any change in the BIOS so it probably still shows that is S0 mode. I'm hoping that the "override" in PlatformAoAcOverride means override the setting in the BIOS so I don't need to do anything more. I don't know. Hopefully the next version of 11 won't change things. So far, I'm liking S3 mode better. I didn't like my device sounding like a plane getting ready to takeoff frequently when it was in Modern Standby. I would still be curious to know what it is actually doing in case I'm forced to go back to S0.

when my pc went to sleep
Your computer did not Sleep when you had S0.
S0 Modern standby [aka S0 Low power idle] is an idle condition not Sleep.
S0 computers cannot Sleep.

I'm glad that disabling S0 worked for you and automatically enabled S3 Sleep.
- Several people here & in TenForums have reported the same - that using this tutorial's method of disabling S0 Modern standby automatically enabled S3 Sleep.​
- It didn't work for me. I have disabled S0 and all I'm left with is On and Hibernation.​
There is nothing left for you to do.
- You can look in the Bios out of interest but you will not need to change anything there.​


I would still be curious to know what it is actually doing in case I'm forced to go back to S0.
S0 Modern standby progressively throttles activity except 'approved' activities such as WU & the Windows 10 mail app. Task scheduler, for example, does not work during S0.

There are, in effect, four Power/Computer states for an S0 Modern standby [aka S0 Low power idle] computer
- Computer on, Monitor on - Work can be done on the computer.
- Computer on, Monitor off = S0 {The monitor turning off initiates S0 Modern standby i.e. idle} - S0 progressively shuts down user-initiated processes. No user-desired activities start, only MS-desired ones such as WU & their built-in email app.
- Hibernate
- Off

I could post so many links to S0 technical documents that you could waste an entire month studying them but I have no reason to hate you that much.
