You had S0 Modern standby. No ifs, no buts, not maybes.
Why did you write, "showing up as enabled when it shouldn't"? I think that statement indicates a misunderstanding.

Not all computers can enable S3 Sleep.
I'm in the same boat as you. I disabled S0 Modern standby but that did not enable S3 Sleep. So I am left with only these power states: On, Hibernation, Off.
I regard it as better than having S0 Modern standby.

All the best,
Denis

I wrote that it "shouldn't be" enabled because I thought once I followed that tutorial with the CMD commands and the registry alterations it would disable it.

Yes I did not have a correct understanding of how it worked. I thought when it says S3 is not supported it meant that it just wasn't enabled or something. That was wrong

I just have to stick with hibernate

If the command


PowerCfg -a

says that S0 Modern standby is available then it is still enabled [whether it is network connected or disconnected].

If that S0 Modern standby entry is not shown in the line following The following sleep states are available on this system: then it is disabled and that should be confirmed by an entry lower down saying so.

If you are in any doubt at all then post your
PowerCfg -a results to get comments.

All the best,
Denis

Technically speaking, that was not wrong, as this depends on whether you look at it from the user experience point of view. Microsoft actually even confirms it (seee the link I gave). In essence, the BIOS / UEFI firmware uses ACPI tables (more specifically, the DSDT) to 'tell' the OS that the system hardware supports the S3 power state. An implication of this is that laptop manufacturers can still choose to design the UEFI firmware in such a way that DSDT tells the OS that the system hardware does not support S3 even when the reality is that the system hardware does in fact support S3. This is where overriding the DSDT yourself may prove to be worth giving a shot, like how I already tried to explain. (If you feel up to it, etc..)

Also keep in mind that most hardware manufacturers have not dropped S3 support. All of Intel's 12th gen CPUs still support it. More than likely, your laptop's motherboard will support it too. But if, for example, S3 is not supported by the internal WiFi card that is installed in your laptop's M.2 socket, then this might explain why the laptop manufacturer in question has disabled support (i.e. by designing the UEFI firmware in such a specific way that support will be disabled in DSDT) you might be able to work around that problem. That is, by simply replacing the card with a different (M.2 compatible) internal WiFi card, such as an Intel AX200 card. The latter card does support S3 so, as a result, it should not cause the laptop to crash when it tries to enter the S3 sleep state. (Still assuming that you are able to bring back S3, by overriding the DSDT.)

That is entirely up to you to decide. It's your laptop, I'm only here to help. The interesting part IMO is that rEFInd lets you avoid having to flash the EEPROM chip of the motherboard with an unofficial (modded) version of the laptop's UEFI firmware. It's interesting because flashing the chip in any non official way is probably going to void the warranty.

As for using hibernate in lieu of Modern Standby. I know that a lot of people are able to use hibernate without problems. But a lot of them are not. Personally, I, have encountered enough problems with it to conclude that it isn't for me. So, for me, that would be a serious dealbreaker, no matter what the manufacturers say. But whatever it is that you decide, good luck with your adventure.. again.

Also verify that the setting is still properly in effect in the Windows registry:
reg query HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride
should return:

Code:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power
    PlatformAoAcOverride    REG_DWORD    0x0

You know.. just so you can be completely sure that Lenovo Vantage hasn't automatically removed the setting or anything like that, or else you could be chasing your own tail like basically forever and still be unaware of what's going on.

Thanks. With the Xiasl, it looked a bit complex for me, but Ill give it a shot. Your Instructions seem pretty straight forward. But that is just to inspect what is present, not to alter or override it?

As far as cmd, yes I have the return results you noted.

Yeah, it's just so you can have a quick look at the DSDT, so you can find out if an S3 object has been put in there by your laptop's UEFI firmware or not, and, if yes, you should then be able to also view that object's code that will be automagically decompiled for you. (All completely free of charge, and at no extra cost.)

Hey, thanks so much for writing this.

I have a surface pro 8, and I found it is using modern standby S0.

The question here is that I can't continue playing my music after I press the power button, and I can't see "Turn off the display" in power options.

I tried your method and successfully disabled modern standby, and I was able to choose "Turn off the display" as well.
but S3 is not turned on due to the reason that the firmware does not support, and hibernate works really bad on my surface pro because of the very slow launching speed.

I was wondering if there's any method allows me to turn off the display only in S0 state or keep music playing when on sleep mode?

Thanks again for your great work.

If needed, my music player is Spotify downloaded from Microsoft Store.

I'm afraid not. The display going off triggers S0 Modern standby.

I did, for a while, adopt a workaround that might suit you. It prevents S0 Modern standby being triggered. It allows music to keep playing.
- Power options set to keep the display on always
- Screensaver - set to display a blank screensaver after NNN minutes so my display would not be staring at me all day when I was not using the computer but left it on.

Thanks for your reply!

This works for me as well, but is not the solution.

What I face is that when I use surface pro 8 as a tablet and listen to music, I have to keep the screen on instead of pressing the power button and enjoying music like a normal tablet.

in the meanwhile, I found that the music wont stop after the system went to sleep automatically, but that's not that case when I use the power button, the music stops as soon as I press it.

And my suggestion achieves that. The screen is always "on" but using a black screensaver makes it look off.

NovaNo1r said:

I don't know what you've got your power button set up to do.
Power options, Choose what the buttons do lets you set it up for your choice of - Shutdown, Restart, "Sleep", Hibernate.
Mine is set to Hibernate. So I only press the power button when that is what I want to do.

but I still have to wait for N minutes before that, if I set it too small, it would affect my normal usage, but if I set it too long, it would be no different as well. And accroding to my test, the Power & battery > Screen and sleep setting will works even better.

What I want to achieve is to turn off it at anytime just like a normal tablet, but thanks for your suggestion, maybe we can add a shortcut to enable the screensaver at any time we want.

But accroding to what I found

The music wont stop after the system went to sleep automatically after waiting N minutes I have set in "Power & battery > Screen and sleep"

I still think there could be a better way to achieve this, or in another word, let the power button trigger the "sleep(triggered by waiting)" action.

I also have a shortcut to that screensaver that I can click on anytime I want without any waiting.
C:\Windows\System32\scrnsave.scr

It works, but not the best. Thank you anyway for your kind help.

Is it possible to listen to the PowerButton Pressed Event or to hook the sleep process?

In that case, we can determine whether to sleep or just simply run the screensaver.

There's also a Do nothing option on the Power button so perhaps that still triggers an event that you can find in Event viewer. If so, you can attach a task to it that will run when you press it. You can make that task do whatever you want.

I have never investigated that [possible] Power button pressed event.
I suggest you look in Event viewer, Custom view, Administrative events. Check that it is set to date-time descending. Press the power button [after setting it to Do nothing - remember to press Save at the bottom of the dialog], Refresh the Event viewer view then see if anything useful shows up.
[I'm on my Windows 10 computer at the moment. It does not create any event when the Power button is pressed if it has been set to Do nothing. I doubt that Windows 11 is any different]

Best of luck,
Denis

What you want is what it should do by default as long as power button isn't set to hibernate or shutdown, although even fresh out of the box there's some caveats like where the music/media comes from and whether it was built to play in the background like Android would with media streams and a background media thread, or uses legacy sound APIs that cut off when the system goes to sleep or the screen locks or whatever. Although if that was really the issue that will happen if if the system idles to sleep, so it really is likely that the power key is doing something different like you guys already discussed. And that's separate from any issues introduced by different sleep states or changes to them, I won't even try guess there because it still throws me through a loop and is better covered by experts here with more experience with it anyway.

One thing I've noticed is that even if I have an extremely long timer on my screens turning off (I think 4 or 5 hours), if I lock my screen they will idle off almost immediately (30 seconds or so). In my case this is desired but this might be something similar to what you want, a very close to real-time screen off ability without having to make your timer very short, just locking the screen.

Bless you Brink. I have been pulling my hair out over this, and switching back to S3 standby seems to have solved my issues.

I just wanted the laptop to be in sleep (where only the power button would wake) when I put it in my backpack lol.

Bought this Lenovo X1 and I hadn't been able to figure out how to keep it from waking itself. I followed other guides to revoke waking permissions from individual devices and found that my install has no power management tabs made available for HID in the device manager or elsewhere. Adding the appropriate registry key/dword wouldn't even enable the tab. Running the command prompt commands provided in some answers on superuser showed no devices with permission to wake and no history of waking from sleep after doing so... what a nightmare.

@Brink,

I have just discovered two facts that were new (to me) about S0 Modern standby. I think you might usefully add them to the tutorial.
I used a newly delivered computer for my tests, an HP Envy 17-cr0001na
1 In a two hour test of S0 Modern standby [network connected] the power consumed was about 0.5WHr an hour {about 1% of its battery power an hour} which is the same as the last time I tested power consumption during S3 Sleep. I had no idea its power usage was so low.
2 It is possible for the PowerCfg -a results to say that S3 Sleep has become enabled by the Registry change that disabled S0 Modern standby yet the computer can encounter fatal errors when S3 Sleep is then attempted. So the PowerCfg -a results are not the whole story; S3 Sleep must then be tested. My computer froze so catastrophically that, in most of my attempts, I could not even use the Power button to force the computer off until I'd disconnected then reconnected the external power input.

HP Tech support could not resolve the problem. I'm returning the computer for a refund.

All the best,
Denis

Hello Denis,

Congrats on the new laptop.

As a test, see how S0 does with network connectivity disabled below. That's what usually uses the most power during S0.

Enable or Disable Network Connectivity in Modern Standby in Windows 11 Tutorial

This tutorial will show you how to enable or disable network connectivity during Modern Standby while on battery and/or plugged in on a Windows 10 and Windows 11 device. In Windows 10 and Windows 11, there are two power models for PCs: S3 and Modern Standby (S0 Low Power Idle). The S3 power...
