I'm not sure how to apply that.

The method I use via AutoHotkey is in fact the same as making a shortcut on your desktop with:

%windir%\System32\rundll32.exe powrprof.dll,SetSuspendState

The only difference would be, that you would have to click that shortcut for setting the PC in sleep mode.

But while you have another setting in your BIOS (S0 in stead of S3, I dont know if that is functioning. I think it would, because in the past I used older computers where the modern standby was not there and I used the same command.

I used that on a programmable key on my Microsoft keyboard using the Microsoft Mouse and Keyboard Center app. But nowadays I have a keyboard from a different make, so that app does not function anymore.

If on my system I switch off the electrical fuse (or the main switch where all my computer equipment has it's power from), that computer will not go into sleep. It will be switched off immediately and when switched on again, it will tell me that it has been shut down suddenly because of a power failure.

So for me your Option ten is no option at all!

If I would use a battery driven computer like a laptop (which I don't have) , that would indeed function, but it would be rediculous to do that. Every time I would like to set the computer to sleep the battery would be drained until almost empty, which is not good for the lifetime of that battery. While I am setting the computer into the sleep state several times a day, your method would soon ruin my system (if I would posess a laptop).

And if after 'sleep' by switching off the mains I would need the laptop without mains, it would not function, because the battery is empty.

So unless you posted your post as a joke, I don't see the use of it at all.

You're right. I'm working on my method. we need to consider the prison too. better call Saul!

I can invoke sleep by Win+X, followed by U and S.

In my system that functions as well.

Did you try to make a shortcut on your desktop with%windir%\System32\rundll32.exe powrprof.dll,SetSuspendState in it?

Yes, I did, but it didn't work on the new HP Omen laptop. (I also tried that in my old Windows 10 Acer, and the script that you suggested worked perfectly on that)

Could you try to set the value in the BIOS of that laptop to S3, like I showed in #17?
You certainly will have to use some other part of the settings of the BIOS, but 'Modern standby" or S3 should be somewhere.

I searched on the HP site if I could find some user manual for the BIOS options in the lapetop HP Omen 17, but failed.
No detailed instructions found.

Sorry, I should have mentioned that on seeing #17 I did check the BIOS, but the only sleep-related setting I could see was Wake on LAN (on the Configuration screen).

I too have been unable to find any instructions covering the BIOS settings, but the BIOS is seems fairly basic.

No problem at all!

I indeed don't see anything that's pointing onto S3. Though I know, my older PC only had no setting for the Modern standby at all and the command in #24 did work right away. So I don't see why it does not work on your laptop...

I would like to be able to put my PC to sleep using a command, but option 9 results in the computer going into hibernation (as do HDMI's variants). On the other hand, options 4 to 8 do put the computer to sleep, and not into hibernation.

From a command prompt or in the Run dialog (Win + R) or in the Target field of a desktop shortcut, you can:

"%windir%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -ExecutionPolicy Bypass -Command Add-Type -Assembly System.Windows.Forms;[System.Windows.Forms.Application]::SetSuspendState('Suspend',$false,$false)

Specifying the filepath to powershell.exe ensures that the command works with the default PowerShell 5.1 even if PowerShell Core has been installed on the computer. This could help to avoid getting the kind of PowerShell errors that you are experiencing.
Additionally, by adding -NoProfile and -ExecutionPolicy Bypass to the list of parameters we can ensure that any settings in PowerShell profiles and the PowerShell execution policies are ignored.
No admin rights are required to run this specific PowerShell command.
To put the computer in Hibernation instead of Sleep, you can simply substitute 'Suspend' with 'Hibernate' in the command.
On computers that support Modern Standby, putting the computer to Sleep doesn't work like this; you have to use a completely different method to achieve this specific goal (e.g., this method).

Many thanks for the detailed posting, hdmi. Sadly, even this suggestion fails to put the laptop into sleep state.

try this app (test to see if it puts your pc to sleep). you need to

1) disable Windows Power Plan screen off/sleep

OR

2) set windows power plan settings to a longer time than autooff is set to (so autooff takes effect first)

I can be over-thorough, and tried both methods just in case.

Many thanks for the suggestion. I've downloaded and installed the app, but it doesn't appear to deal with sleep. The actions that the app can trigger are:
Shut down Windows
Restart Windows
Turn off the display
Turn on the display
Lock Windows
Show an alarm message
Run a program
Terminate a program
Rerun a program

Yes, it is strange. Two of the options (including putting the computer to sleep) are missing from the installation on my laptop).

I have been thinking about why your laptop might have been set by the manufacturer (if he did indeed) not to use sleep.
And came to the conclusion that for most laptops the pure 'sleep' (modern standby) function is a rather unwanted thing. Because the laptop will not be switched off, but put in a situation where many parts of the motherboard still will be functioning and so will be drawing current, draining the battery.

Of course this would not be any problem when you allways have the laptop on mains supply!

Then I went searching for some way to set a registryvalue to block that modern standby and found this tutorial:

Disable Modern Standby in Windows 10 and Windows 11

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. 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...

www.elevenforum.com

If the modern standby would have been disabled, there would be a registry value like this one:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power]
"PlatformAoAcOverride"=dword:00000000

If that entry is there, you only would have to delete it or use the registryfile in the tutorial "Enable_Modern_Standby.reg".

Of course it is not sure that exactly this registry entry was used to disable sleep, but you could have a look for this one.

I myself have disabled the lock command in all available menus by such a registry-edit.
Found that as well in one of the tutorials. Thanks to @Brink

Edit: just read in other Internet topics that modern standby would be exactly the opposite from what I supposed. So the S0 situation would be modern standby, while S3 is the classic one. In that case you might try the opposite way: disable modern standby and look if that would help.

I am not sure at all that the issue I found will matter at all, but it is an attempt to help.

It is very practical to look in the registry before you do any changes at all at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
and look if the value PlatformAoAcOverride is there , if yes , what it's value is.

here, its not a permanent solution, but until we can track down exactly why you dont have many options for Sleep... use this autohotkey script (i've attached the .exe if you want for ease. it will invoke those keystrokes so you can pin to taskbar, etc to click to sleep

ahk code:

Code:

Send, #x
sleep, 100
Send, U
Sleep, 100  
Send, S

Go to device manager and make sure your display adapter and chipset drivers are correct.

This version should work on every Windows 10/11 computer that either supports Standby (S3) aka "Sleep" or supports Standby (S0 Low Power Idle) aka "Modern Standby".

"%windir%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -ExecutionPolicy Bypass -Command "Add-Type -TypeDefinition 'using System; using System.Runtime.InteropServices; public static class User32 { [DllImport(\"user32.dll\", SetLastError = true)] public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam); }' -ReferencedAssemblies System.Windows.Forms; $lines = (powercfg /a) -split \"`r`n\"; $cont = $true; foreach ($line in $lines) { if ($cont) { if ($line -eq 'The following sleep states are available on this system:') { $cont = $false } else { continue } } elseif ($line -eq '    Standby (S3)') { [System.Windows.Forms.Application]::SetSuspendState('Suspend', $false, $false); break } elseif ($line -eq '    Standby (S0 Low Power Idle)') { Start-Sleep -Seconds 2; $null = [User32]::SendMessage((New-Object System.Windows.Forms.Form).Handle.ToInt32(), 0x0112, 0xF170, 2); break } elseif ($line -eq 'The following sleep states are not available on this system:') { break } }"

I really do appreciate the time that you have spent on this, but I'm sorry to say that my PC is not responding even to this instruction.

As you suggested, I have re-checked the drivers, and they don't appear to be a problem.

This works well! I have used the .exe version that you kindly provided, and have assigned it in the registry to the HP Omen's special keyboard key (intended to be used for a calculator, which I don't need). The laptop now immediately goes to sleep when this key is pressed, and immediately re-awakes when the power key is pressed. I'm very pleased with this solution.

Thank you, dacrone, for this solution. And thank you, also, Brink, Kees, hdmi, and Dronix for your contributions.
