Stop PC "sleeping" when display turns off? v19044.1288

If you've disabled S0, as I also have, it should not sleep when the display turns off.
What have you set in Power options?

Does the command

Code:

PowerCfg -a

confirm that S0 is disabled?

I assume you disabled S0 the normal way.

I'm baffled.
What do the Event logs say is happening when the screen goes off?
You should not see any sleep state transitions but it sounds as though you will.

I suggest you create an Event viewer, Custom view so you can see what's happening.
Here is the [zipped] definition for an Event viewer, Custom view that captures sleep state transitions.
Power - Sleep-Hibernate-S0 transitions.zip
Before importing it, you can read its unzipped xml file in Notepad or, for a better presentation of its contents, by right-clicking and opening in a browser.

To import it:
1 Unzip the file
2 Open Event viewer, click on Import Custom view [on the right-hand side],
3 Browse to and select the xml, Open,
4 Change the name if you want to then OK,
5 You can see the records, on the left-hand side, within the group Custom views.

You can then select the Custom view in Event viewer's left-hand pane.

When reviewing power state transitions, note that S3 Sleep & Hibernation events can only be distinguished, in a computer that has both, by looking at the Details tab of the resume EventID 1 for Hiber* entries that are greater than 0; resuming from S3 Sleep would show Hiber* entries that have the value 0
Resume from Hibernate, Details tab

Resume from S3 Sleep, Details tab



On a similarly confusing note, S0 Modern standby event records are misleadingly labelled as relating to S0 Connected standby whichever state is in force - Connected/Disconnected standby.

When I find specific entries that seem significant, I also run NirSoft's FullEventLogView because that makes it easy to see everything in chronological order enabling the events before & after the event of interest to be considered.


All the best,

OK.
So it is not sleeping.

I wonder if perhaps it is freezing when the display goes off.
Personally, I'd go to Acer to get another copy of the display driver & install it even if it is the same version that you already have.
That would cater for the possibility that your display driver has become corrupted.

Add or Remove Lid close action from Power Options in Windows You probably have all these settings like you want.

Not Bob,

I have never seen or considered a situation such as yours.

Is hibernation enabled? If not, I wonder if enabling it might yield additional info.

1 If Hibernation is enabled then perhaps you will see a record of hibernation when the problem occurs.
2 If there's still nothing, you could try searching through events that take place when the problem occurs. I think the NirSoft utility I mentioned will be the easiest one to use to look through.
3 If there's still nothing, I think it shows that your computer cannot cope with S0 being disabled. That's a disaster. Perhaps you should change Power options to keep the display on the whole time & then set up a fairly dark screensaver to come on after a period so you don't have the screen staring at you all day. I did this as a sort of halfway house when I still had S0 enabled but it will work equally well whether S0 is enabled or not.
