[QUOTE="mm1352000, post: 1160710, member: 82144"] Sure. :) My theory is... We only want to trigger the "Resuming operation of user interface" etc. part of the patch when the PC is waking up (after PBT_EVENT.PBT_APMRESUMEAUTOMATIC is received but PBT_EVENT.PBT_APMRESUMESUSPEND is not received), not when it is suspended/suspending. _resumedAutomatic is set to false when PBT_EVENT.PBT_APMSUSPEND is received: [URL]https://github.com/MediaPortal/MediaPortal-1/blob/master/mediaportal/MediaPortal.Application/MediaPortal.cs#L1779[/URL] ...and set to true when PBT_EVENT.PBT_APMRESUMEAUTOMATIC is received: [URL]https://github.com/MediaPortal/MediaPortal-1/blob/master/mediaportal/MediaPortal.Application/MediaPortal.cs#L1851[/URL] So, we know that if _resumedAutomatic is false the PC is suspending/suspended, and if _resumedAutomatic is true we know that the PC is waking up. Therefore we can check _resumedAutomatic to check if the patch code should be executed. If _resumedAutomatic is true, the PC is waking so it is okay to execute the patch code; otherwise the patch code should not be executed. Is it clear? :) AFAIK PBT_APMRESUMEAUTOMATIC comes alone if the PC wakes without user input (eg. scheduled recording or EPG grabbing). If/when the user provides input later, Windows should send PBT_APMRESUMESUSPEND. However for Jeffrios and keeperoftracken that PBT_APMRESUMESUSPEND is never sent/received. It is strange... but I can't solve problems with Windows or third party software. I can only provide a patch/workaround for MediaPortal. [/QUOTE]
