Lock Screen Timeout Settings

[Bankesy]

Hi all,

 

Not sure if I have forgotten to set something or if I have not set something right but looking at some Windows 11 devices we have, I can see via Control Panel power settings that the monitor is set to go to sleep after 25 minutes but I wonder if this only applies when left open on desktop because from lock screen, monitors are going blank after a minute or so.

 

It doesn't look like the devices (Intel NUCs) are going to sleep themselves because the power light is still a solid blue, mouse laser still on etc. but sometimes users cannot wake the devices up through mouse, keyboard or power button input and end up restarting from the plug.

Have not tested but will try to see if being connected to projector\SMART board makes any difference.

 

Thanks

I've seen OS corruption do that before - have you tried an in-place upgrade in the Settings app -> System -> Recovery -> "Fix problems using Windows Update"?

 

Also probably worth checking if drivers, BIOS, etc. are up-to-date in case that they could be causing it.

Monitor off and PC sleep are different settings. 'Edit Power Plan' control panel (via Start/Run) is a good place to set this, and enforce centrally. BIOS settings might be somewhere to look to configure sleep modes correctly.

 

The login screen is a different setting to change. That goes off after 60 seconds?

It's controlled by the hidden VIDEOCONLOCK setting.

 

Unhide the setting:
powercfg.exe -ATTRIBUTES SUB_VIDEO VIDEOCONLOCK -ATTRIB_HIDE

 

Query the setting: Default value is 0x3C (60 Seconds)
powercfg.exe /QUERY SCHEME_CURRENT SUB_VIDEO VIDEOCONLOCK

 

Set the setting: 300 seconds (5 minutes)
powercfg.exe /SETACVALUEINDEX SCHEME_CURRENT SUB_VIDEO VIDEOCONLOCK 300

Also look at screen saver timings, as this is separate to monitor / screen sleep timings.

We've got a similar problem with some (not all) of our Lenovo PCs since moving to Windows 11. Manual lock or forced lock after 5 minutes of inactivity and the screen goes blank after a minutes and doesn't always come back. We haven't been informed when it's happened to try wake on lan but it appears it should work.

 

Our classroom PCs aren't set to lock so it doesn't appear to be connected to a touch screen/projector.

Hi all,

 

Just reviving this thread and wanted to ask what you all generally have the setting for "Turn off hard disk" set to.

 

I am guessing that having it set to 1 minute is causing most of my problems here.

 

Thanks

'Never' for us. SSDs will take care of themselves from a power point of view.
