[QUOTE="mm1352000, post: 1178510, member: 82144"] [USER=56931]@Tuomaa[/USER] Thanks for your analysis. :) As you can see from the log file, the events that MediaPortal receives from Windows in the MP1-2 case are: 1. [2016-03-13 11:07:05,020] [Log ] [MPMain ] [INFO ] - Main: WM_POWERBROADCAST (PBT_APMRESUMEAUTOMATIC) 2. [2016-03-13 11:07:10,050] [Log ] [MPMain ] [INFO ] - Main: WM_POWERBROADCAST (PBT_POWERSETTINGCHANGE) ... [2016-03-13 11:07:10,050] [Log ] [MPMain ] [INFO ] - Main: The display is on 3. [2016-03-13 11:09:10,753] [Log ] [MPMain ] [INFO ] - Main: WM_POWERBROADCAST (PBT_POWERSETTINGCHANGE) [2016-03-13 11:09:10,769] [Log ] [MPMain ] [INFO ] - Main: User is providing input to the session So, Windows never sends WM_POWERBROADCAST + PBT_APMRESUMESUSPEND message that you mentioned. Of course Windows [I]should[/I] have sent that message... but from experience with many similar reports from various people, it has become obvious that we can't assume that message will be sent/received. Perhaps there's a driver problem or rogue application on these people's systems. I don't know... Anyway, if you look at the MP code you will see that MP now recognises that Windows failed to send the message. We attempt to generate the message that Windows should have sent for all the plugins that have WndProc()s: [URL]https://github.com/MediaPortal/MediaPortal-1/blob/master/mediaportal/MediaPortal.Application/MediaPortal.cs#L2036[/URL] If CEC Remote does not have a WndProc, it obviously won't receive the message from MP. In that case I recommend CEC Remote code to detect the situation in the same way that MP does (by detection of WM_POWERBROADCAST + PBT_POWERSETTINGCHANGE + GUID_SESSION_USER_PRESENCE). I hope that helps. :) [/QUOTE]
