    S0 Low Power Idle (Modern Standby) and wake from sleep


    Powercfg /a tells that the only supported sleep state is S0 Low Power Idle. That is a very confusing thing, I could not find satisfactory information by googling. Is that sleep state supposed to arm keyboard/mouse wakeup the exact same way than S3? I see that if I force S3 (the HKLM\System\CurrentControlSet\Control\Power\PlatformAoAcOverride=0 trick), then sleep mode results in pulsating power button LED. However, when trying to wake from that state, not only keyboard/mouse doesn't work for wakeup, but also pressing the power button results in a crash. Fans turn on, power light turns permanently on, but nothing else happens, no image on the screen. Only holding power down (shutdown) will help at that point. So in the S0 mode at least I can resume from sleep using power button, but I can't resume with keyboard/mouse. How do I troubleshoot this? I tried maybe 15 different things already, nothing made any difference. When doing "powercfg /devicequery wake_armed" the keyboard and the mouse are listed. Also the laptop's integrated keyboard doesn't wake the computer and I have done "[x] Allow this device to wake the computer" everywhere I can think of. Using Windows 10 version 21H1. - - - Updated - - - If I insert an old mouse into the USB-A port directly on the laptop, and go to sleep, the mouse does light up (gets power). But no matter how many times I click the mouse, the computer doesn't wake up (and I made sure "[x] Allow this device to wake the computer" is enabled).

  2. Scheduled wake from DRIPs (Modern Standby)

    The sleep I am referring to is obviously the connected or disconnected standby not the traditional S3 sleep, I think this is obvious from my reasoning.

    The term “sleep” in a modern standby capable system is a synonymous of connected or disconnected standby since S3 traditional sleep is disabled when S0 low-power idle is enabled.

    I really don’t see where you got the idea that I was referring to the traditional S3 sleep.

    Maybe the term “sleep” confused you.

    Excessive battery drain during S0 sleep (modern standby)

    S0 Modern standby is not sleep but a glorified idle condition. That's why it uses so much power - the computer is on during S0.

    Scheduled wake from DRIPs (Modern Standby)

    Mike,

    You do realise that Modern standby is not sleep? Modern standby is an idle condition.

    It is rare for a computer that is capable of modern standby to be capable of sleep [S3]. You can find out what states a computer is capable of by entering this command
    Code:
    PowerCfg refers to modern standby as 'S0 Low Power Idle'.
