'Connected Standby' Support

[VenusProject2]

Hello, I couldn't find any reference in the forums to 'Connected Standby.' I am looking for a solution to creating a script to force my laptop to enter what Microsoft refers to as 'Connected Standby'.

Here is a vanilla ice-cream script that supports 'Standby' (S3) or Sleep after a set number of seconds

#RequireAdmin
#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_UseX64=y
#AutoIt3Wrapper_Res_requestedExecutionLevel=requireAdministrator
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****

#include <AutoItConstants.au3>
#include <MsgBoxConstants.au3>


$cd = 20
Do
    $cd = $cd - 1
    $i = MsgBox(262180, "", "Sleep in " & $cd & " seconds", 1)
    If $i = $IDNO Then ExitLoop;No Sleep
    If $i = $IDYES Then ExitLoop;Yes Sleep
Until $cd = 0

If $i = $IDTIMEOUT Or $i = $IDYES Then
    $s = Shutdown($SD_STANDBY)
    ;$s = Shutdown(BitOR($SD_FORCE,  $SD_REBOOT))
    ;$s = Shutdown(BitOR($SD_STANDBY,  $SD_FORCE))
    ConsoleWrite("$s = 1 => OK = " & $s & @CRLF)
EndIf

However this script doesn't put my new laptop into 'Connected Standby' the script Shutdown($SD_STANDBY) returns 0 i.e. failed.

Any help appreciated thanks.

What is the value of @error after the Shutdown function call?

[VenusProject2]

Thanks the @error = 1300

Windows API GetLastError() a quick check reveals the following explanation: Quote ERROR_NOT_ALL_ASSIGNED 1300 (0x514) Not all privileges or groups referenced are assigned to the caller.   UAC??

Hmmmm... it seems this can be done with AutoHotKey (see the last post in this link).

It therefore must be possible with AutoIT. 😓

the equivalent in autoit would be:

;AHK SendMessage, 0x112, 0xF170, 2,, Program Manager
;AHK SendMessage, Msg , wParam, lParam, Control, WinTitle, WinText, ExcludeTitle, ExcludeText, Timeout

#include <SendMessage.au3>

Local $hWnd = WinGetHandle("[CLASS:Progman]")
;or Local $hWnd = WinGetHandle("[TITLE:Program Manager]")
_SendMessage ($hWnd, 0x112, 0xF170, 2)

;or maybe??
_SendMessage ("[TITLE:Program Manager]", 0x112, 0xF170, 2)

@Bilgus, The first one seems to work on my system.

Lets see what results @VenusProject2 gets ...

Are you certain your computer can use that power mode? Open a command prompt and run the command "powercfg /a" and then look for the state Standby (S0 Low Power Idle) in the list. You'll see if it is even possible to use it. The laptop I'm running right now isn't capable of using that mode.

Local $hWnd = WinGetHandle("[CLASS:Progman]")
_SendMessage ($hWnd, 0x112, 0xF170, 2)

Thanks Bilgus & ModemJunki this worked well, now I am faced with finding a solution to get Scheduled Tasks to 'wake' from Connected Standby. Scheduled Tasks work well for Standby (S3) mode, however, I haven't yet found a solution to wake from Microsoft's 'Connected Standby'. Perhaps there is an AutoIt solution?

Probably best to Open a new Forum Topic

Thanks for your reply. Seems to be supported, but nothing else is.

powercfg /a
The following sleep states are available on this system:
    Standby (S0 Low Power Idle) Network Disconnected

The following sleep states are not available on this system:
    Standby (S1)
        The system firmware does not support this standby state.
        This standby state is disabled when S0 low power idle is supported.

    Standby (S2)
        The system firmware does not support this standby state.
        This standby state is disabled when S0 low power idle is supported.

    Standby (S3)
        This standby state is disabled when S0 low power idle is supported.

    Hibernate
        Hibernation has not been enabled.

    Hybrid Sleep
        Standby (S3) is not available.
        Hibernation is not available.

    Fast Startup
        Hibernation is not available.

    Standby (S0 Low Power Idle) Network Connected
        Connectivity in standby is not supported.

 

In the registry it is possible to DISABLE the 'Connected Standby'

RegistryKey: HKLM>System>CurrentControlSet001>Control>Power>>CSEnabled=1 Default is set to 1, set it to 0 and reboot. And Standby (S3) becomes available, I did test it however upon waking from S3 the graphics becomes scrambled & or the OS freezes requiring a hard shutdown. According to ACER(OEM) this is not supported. Seems I am stuck with 'Connected Standby'

Try switching hibernation on (powercfg /hibernate on) and check again. This will allow the other settings that mention hibernation to be allowed (Hibernation, Fast Startup, and hybrid sleep).

Hmmm...

https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources

Quick and dirty test - schedule a mouse move or keypress script?

; --------------------------------------------------
; Move mouse, then put it back back 
; --------------------------------------------------
Func _MoveMouse($PixX=1, $PixY=1,$Speed=5)
    Local $pos = MouseGetPos()
    MouseMove($pos[0] + $PixX, $pos[1] + $PixY, $Speed)
    MouseMove($pos[0], $pos[1], $Speed)
EndFunc   ;==> _MoveMouse

Thanks, yes I had read that article yesterday, and sent feedback to request custom user defined sources for waking from modern standby, e.g. a Scheduled Task. I appreciate the mouse move idea, not bad at all. I will test it and get back to you. It seems that only approved Microsoft app store software is able to run when in Modern Standby, e.g Skype

Hi, did you find a solution on that? I'm just sticking to Windows 10 1909 because 2004 and the following versions force modern standby and my  AutoIT automation software is no longer able to wake up the computer.
