Laptop has no sleep option or sleep states?

Hello, since I purchased my laptop in 2022 it's sleep option only turned off the screen.
After a number of tutorials and regedits, I managed to disable the "Away policy", allowing it to properly sleep... once. After a restart the sleep button has permanently vanished.



Also apparently no sleep states are supported?


It's been like this for months and I haven't been able to get anything going with any tutorials or bios resets.

The specs are as follows:
Windows 22H2 (Build 19045.4291)
Dell XPS 17 9710


My work takes an immense time to turn on and leaving my laptop running 24/7 is not ideal.
Any help would be greatly appreciated. Thankyou!

Do everything, including Fast Startup, if haven't already done so:
Why Is "Turn on Fast Startup" Greyed out on Windows? - Technipages.
If done all those steps, does it work now?

First 2 steps don't apply as you can see there are no other options in my power options.
Also I followed the regedit and my "HiberbootEnabled" is already set to 1, so it should already be enabled, but isn't.

Put this in notepad, save it as a .bat file, run it.

:Do nothing when you close the lid
powercfg /setACvalueIndex scheme_current sub_buttons lidAction 0

1 Did you disable S0 Low power idle or has it always been disabled?
Some of your comments make me think you started off with S0 Low power idle enabled and one of the actions you took was to disable it. Not all computers behave themselves after such a change [I had one that kept locking up after I had disabled S0 Low power idle and I had to boot to my system imaging utility's boot disk then restore the prior system image to get it working again].
S0 Low power idle is also called S0 Modern standby & S0ix.

2 Do you have a list of the actions you have taken?
If not, and I do not say this lightly, it might be better to reinstall Windows so you can start troubleshooting from a known state.

3 Which display driver does Device manager say you are using?

1. I don't know what that is exactly. Is that where the computer remains on, but only the screen shuts off? (Similar to if you step away for 5 min). That's what I was initially aiming to fix, so I could let my computer rest and return later to my open programs.

2. I first ran some cmd command to force my computer into a full sleep which actually worked once, however followup attempts game the same screen-off but pc fully on standby.

I then did this guide to hopefully disable the fake-sleep (S0)
Stop entering Away Mode – nullteilerfrei
By enabling the "Allow Away Mode Policy" option (shown in my first image at the top) and disabling it there.

Also I worry about a clean install, as it took a LOT of time & headaches to get all my work programs at the right version, with the right extensions, etc, working properly.

Would a restore point help revert my changes in this case? (Note that I would still like to figure out how to make the computer actually sleep, to the point where played music stops and mouse movement does not instantly enable the screen)

Thank you for the help so far btw.


P.s. Also yes I noticed the actions posted above seem to be removing sleep from the lid & power button, which is already my case.

Labtops ( or even those DELL/HP all in one PC's ) do not sleep no matter what because there is no battery available.
The same where there is a "power-issue" ( the GPU uses another PSU the Operating system have no control over ) with an external GPU.

If you force the computer to sleep and there is no battery or it has power-issues with another device it will never sleep. You might be able to use "Hibernate" ( turn off with all settings as you left it ), but never sleep.

I would test it with USB with "Windows 10 PE" installed. Just to see if it will sleep. You could also try "testing" a linux install like Ubuntu and go into sleep mode ( if it is supported without install ).

In the BIOS ( UEFI or whatever ) you need to make sure your computer has all the settings correct involved with sleep modes, and so forth. It is different for most machines. You could prevent sleep mode from the BIOS as well, among other settings.
