This relates to Windows 10 Pro version 1903.

The ideal behavior I want is for my laptop to:

  • turn off the display after a few minutes of inactivity
  • go to sleep if inactive for a longer period (an hour)
  • if it is in a "display off" state (not yet sleeping), I want it to resume without the lock screen
  • if it has gone to sleep (either by extended inactivity or commanded by the power button) that it will wake to the lock screen.

I haven't found the combination of settings to achieve this; from all the combinations I have tried (including group policy settings), lock screen seems to be all or nothing; if it wakes from sleep to the lock screen then it will also go to the lock screen when it resumes from a "display off" state; if it resumes from "display off" without the lock screen, then it will also wake without the lock screen.

Is there a combination of settings I am overlooking to achieve the behavior I want? Does Windows 10 1903 even allow for it?

EDIT:

I tried to follow this answer to my question, but found that my system does not offer the "System unattended sleep" option... is there a group policy option or registry setting I need to set/modify to enable it?

Do it this way:

  • In Start > Change screen saver, set the screen saver to "None"
  • In Start > Power Options > Change plan settings, set
    • Turn off the display to, say, "5 minutes"
    • Put the computer to sleep to "1 hour"
  • Start Task Scheduler and create a new task, as follows:
    • General: Give it a name; check "Run only when user is logged on"
    • Trigger: "On an event"; Custom; New Event Filter, defined as Level: Information; Source: Power-Troubleshooter; Event id:1
    • Action: Start a program; Program: rundll32.exe; Arguments: user32.dll,LockWorkStation

Enabling and setting System Unattended Sleep Timeout to match your desired sleep timeout should allow Display off to function as you desire. (see first answer) To enable, edit the Attributes value under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\238C9FA8-0AAD-41ED-83F4-97BE242C8F20\7bc4a2f9-d8fc-4469-b07b-33eb785aaca0 Regedit

Then, Advanced Power Options will show: enter image description here

  • Seems my advanced power options don't match yours; I don't have a "System unattended sleep timeout"

  • You have to add it through a Registry edit. That's in the link. Jul 13, 2019 at 19:19
  • System unattended sleep timeout power setting is the idle timeout before the system returns to a low power sleep state after waking unattended. What's the connection here?

  • Despite it official description, its default value of 2 minutes seems to be what triggers "premature" sleep. Jul 13, 2019 at 19:29
