Also - go into “edit power plan” and change what power buttons do > make sure it’s not set to “nothing”. While on that screen, also uncheck fast startup.

Isn't that power button setting for when the computer is awake? Worth a try though. Will report back shortly.

I've disabled fast startup in UEFI.

If neither work, try this too:

Power options advanced settings > allow hybrid sleep = off
And
allow wake timers = enabled

Yeah no sadly didn't seem to work. The first option isn't even listed, and the second one was already enabled when plugged in (which I am). Switching the power button to do nothing didn't help either. Thanks for trying to help. Guess I'll just need to learn to live with the useless and annoying S0.

I'm just wondering why `powercfg` gives me that optimistic output saying S3 is enabled and S0 is disabled after running the .reg file.

See if you have the bios setting or one similar to the one listed here.

Fast Boot is in UEFI. Fast Startup is where @dacrone said, but not if Hibernate is off, as Fast Startup is always off if Hibernate is off.
(The powercfg a command output that you posted in your post #175 says that it's off.)

if you have hibernate disabled (i hadn't noticed), re-enable it via cmd and then try sleep again and see if your mouse wakes the pc. let me know.

It appears my system supports S3. This is what I get after disabling Modern Standby

alibi said:
However, I now get the issue like some others where it won't wake up after I put it to sleep until I force-shut-down it by holding the power button.

So does my laptop not support S3 despite it clearly being listed under the available states?

It is possible for a computer to show that it supports S3 Sleep even if it does not.
I also experienced a case in which, like yours, disabling S0ix made S3 Sleep appear to be in force only for me to discover that I had to force the computer off with the power button if I tried to sleep it.

Since then I have learnt to tame S0ix so I do not disable it anymore.

Sorry for such a delayed response guys. Tried everything you three suggested, all to no avail. Disabled fast startup and fast boot, enabled hibernation, disabled hibernation, USB suspend was already off in BIOS.

Seems to be the case here. Very annoying that not only is S0 forced onto the user, Microsoft and OEMs also falsely mislead the user into thinking S3 is supported.

Thanks very much for the linked S3 guides @Try3. That'll be my reading for the weekend.

I asked sales desks at Dell & HP if my selected laptops would come with S3 Sleep or could be converted to use S3 Sleep.
- Dell sales did not know. I asked to be transferred to their tech support desk and they refused because tech support are only allowed to talk to customers after purchase. No more Dell laptops for me then.
- HP sales did not know. I asked to be transferred to their tech support desk and they did so. Their tech support were very honest. They said that their documentation was not clear about the subject at all. They also pointed out that I could reject the laptop within a month and they would pay for the return postage. So I went ahead. Those #85, #86 posts of mine reported the experiments I did with their laptop before returning it [even though I had learnt to tame S0 Modern standby, the keyboard was awful - grey markings on grey keys with unintelligible backlight control].

I still wanted a decent Windows 11 test computer [that could become my main computer after Windows 10 support runs out]. In the end, I could not find one that fulfilled my requirements below £3,000 so I compromised with a Lenovo IdeaPad Flex 5 16 16ABR8 that cost £550.
- It has soldered in Ram which cannot be replaced or added to.
- It only has a 16 inch display instead of the 17 inch one I wanted.
- It can only have one 'disk'. I am used to having two and I use the second as an interim backup location.
- But is is a very good laptop - its 16 inch display is just about as good as the 17 inch one I sought, it is powerful enough to become my main computer later on, it is light enough to take over as my 'travel' computer as well.

All the best,
Denis

I ran the reg file to Disable S0 on my new HP Envy laptop. As some had predicted, I no longer have any sleep mode enabled, per PowerCfg -a.
It goes into Hibernation when I tap the Power key.
Are there any other options that I can try?
Thanks

No, there are no other methods.
If your computer maker has created a Bios that cannot handle S3 Sleep then there's nothing you can do about it.

I now live with S0 Modern standby. I have tamed it - see my post #187 above.

All the best,
Denis

Probably not, as I suspect that the vast majority of manufacturers made that impossible on most of their recent laptop models by now, but on some older laptops it is still possible to, at the sacrifice of having to keep Secure Boot disabled in the BIOS, use rEFInd with a custom script, i.e. as an alternative to modding the BIOS in such a way that will restore (or enable, if it is disabled through a condition) the S3 object in the DSDT (Differentiated System Description Table, which is a part of the ACPI specification). I have seen a few reports on the internet several years ago about how this can be made possible on some certain, specific, laptop models at least from Lenovo and Dell. I posted about this particular subject before.

However, if you do that, then the resulting S3 object may not be able to function correctly or may not work at all so then it crashes the laptop immediately the moment when it attempts to enter sleep. It depends on whether all the various hardware components and device drivers thereof are capable to correctly support S3. So if, for example, the internal WiFi adapter card is the only component that is not able to support S3, then simply replacing the card with one that has that ability should do the trick. Whereas if the intestines that do not have that ability also include ones that are impossible to be replaced with ones that do have, then basically, you are SOL (Sh!t Outta Luck).

OK thank you both.
I've read through all the previous pages more carefully and learned a lot.
Based on that, I've made some changes to try to live with Modern Standby.

Based on what I read in the thread, I now have it set to "Sleep" after 1 minute, instead of manually putting it to sleep when I walk away.
It seems very reliable, more so than the old sleep was in previous computers. And I am hoping that the fan running when "asleep" will not occur now.

Others have reported fans running during S0 Modern standby both here and in TenForums.
If your fans are running during S0 Modern standby then your computer must be working. If you have connectivity set to on then it could be running Windows update, the email app, ... [MS have not published a list of which of their favoured apps can run].
If you set connectivity off then the scope for working reduces and the computer should not get as hot.

The behaviour ought to be the same whichever of those two methods you use to put it to "sleep" i.e. into S0 Modern standby.

Best of luck,
Denis

Here's a batchfile I wrote. When you run it, it uses the C# compiler (csc.exe) that is a part of Windows 11 by default, to create a program ScreenOff.exe in the same folder. Then when you run this program, it turns the screen off after waiting for 2 seconds (so the screen won't turn immediately back on if you stop moving your mouse before those 2 seconds are over). On computers that support Modern Standby, turning the screen off is what forces the computer to enter Modern Standby. Hopefully this helps.

Batch:

IF EXIST "%InstallPath%csc.exe" ("%InstallPath%csc.exe" /out:"%~dp0\ScreenOff.exe" /target:winexe "%~dpnx0") ELSE (ECHO ERROR - Missing csc.exe)

I think you are correct. Both methods seem to have difficulty sometimes (but not always) putting the computer to sleep when I have something running - ie if it repeatedly won't go to sleep I sometimes have to close Outlook 365 then it will sleep. And sometimes when there is a game open in Chrome, I have to close Chrome to get it to sleep. But other times, I have both Outlook and the game running, and it goes to sleep after the 1 minute delay without a problem.

Also, the in the instances when it does go to sleep, its behavior is inconsistent. Sometimes after the 1 minute the screen goes off and the computer sleeps almost immediately. Other times, the screen goes off and it takes about 30-45 seconds more before the computer sleeps.

Palermo · Jun 20, 2024

hdmi,
Thanks for the batch file. I'll try that if the situation gets too frustrating.

Palermo · Jun 20, 2024

The worst part is that I can't close the screen on the laptop and feel safe letting it sit on a bed or couch. I've come back twice now and found the fan running and laptop hot. My next step will be to turn off the network connection, like I seen above in this thread. Oddly that does not seem to happen if I leave the screen open and the computer asleep.

"After the screen turns off, a waterfall flow of phases quiets the system to its Sleep state." See: Modern Standby states
So, each time when the waterfall splashes too much water into the computer's face, it may take a while before the computer goes to sleep...
