I have been having an issue where my computer will randomly go to sleep. I've done some digging in Event Viewer and found that it seems to be DisplayFusion triggering the event. I've looked around the settings and I don't see anything that has to do with the computer going to sleep... I'm hoping you all can help me track this down.

I haven't set the DisplayFusion logs to detailed and tried to reproduce yet as the issue is intermittent and it impacts my work. I'm hoping that there's a setting that im just overlooking or that you've seen this before. If not, I can increase the logging level and wait for a reoccurence.

Thanks for the help!

Here are the debug logs. The computer went to sleep around 12:47pm and I turned it back on right after that. This appears to be when I woke it back up:

2019/10/16 12:47:41.4506##_##INFO:L2##_##displayfusion.exe:21172##_##DFHookManager:WndProc_ShellHook##_##-##_##Trigger:SystemWakeFromSleep##_##-

These logs are set to L2 - Detailed.

There aren't any features in DisplayFusion that would be putting the computer to sleep. Those events in Event Viewer are showing that the service was aware that the computer was sleeping, not that it caused it to sleep. The log line you pasted is DisplayFusion detecting that the computer woke from sleep, for the purposes of running any "System Wakes From Sleep" rules on the Settings > Triggers tab. The next time it happens, click the Details tab on the event that shows "Reason: Application API" and there should be a line that looks like this:

<Execution ProcessID="4" ThreadID="2344" />

You can then look at the list on the Windows Task Manager > Details tab to see which process matches the ProcessID (not the ThreadID) from the event log to see which one requested the computer to sleep. Hope that helps!

It looks like it is just a Windows Process. Thanks for at least helping me narrow things down. Now that I know DisplayFusion isn't able to do anything like this, I can focus elsewhere.
