During the testing for another problem with PowerScheduler I noticed this and I've now tracked it down. I'm fairly sure this is caused by the recent changes to allow "PowerScheduler will recover from a critical ShutDown".

Basically what happens is this. If PowerScheduler is in use and a program is scheduled to record and the recording starts while mp is running (not while it is suspended), then after the recording has completed if the user moves to the home screen PowerScheduler will not suspend the system after the set idle time.

How to reproduce
1. Setup to use PowerScheduler:
- ShutDownInterval = 5
- ShutDownMode = suspend
- ForceShutDown = False
- TimerInterval = 30
- WakeUpInterval = 2
- ReinitRecorder = True
2. Start MP
2. Schedule a recording a short time in the future.
3. Go to any non home screen (like MyMusic or MyTV - with TV off).
4. Wait for the recording to start.
5. Move to the home screen.
6. Wait for the recording to finish
7. Wait more than ShutDownInterval, note that MP does not suspend.

What I think is happening is that with the above PowerScheduler is setting a timer for the start of the program (as it should), however because the user is not in the home screen PowerScheduler correctly does not suspend before the program starts to record. However the timer still goes off and this causes the OnWakupTimer method to be called. This call checks to see if the system has previously shutdown correctly and if has not it attempts to "recover" by calling OnSuspend (assuming that OnResume and Start will be called shortly). However the system really has not been shutdown and so there is nothing to recover from. The problem is that OnSuspend cancels the PowerScheduler timer that runs every 30s to check to see if the system should be suspended. So if this is not running then it will not suspend after the program has finished recording and the system is idle.

I'm not 100% what the recovery code was fixing, so my take on a fix for the above may not be correct. But perhaps it would be better to move the code currently in OnWakeupTimer and place it in the window proc just before the code that currently handles the resume messages. That way if the system resumes without having shutdown correctly then the OnSuspend code would be executed thus allowing the OnResume/Start code to run correctly.

Hope this all makes sense....

Hi Bavarian,
Thanks! Let me know if you need anything....

The resum from critical ShutDowns where disabled in the SVN. Have to think about a other procedure for that.

Hi Bavarian,
If it would help you and you have the time, then let me know what the problem was that you have been trying to fix (with the code in OnWakeupTmer), and I'd be happy to try and help......

Same problem here.
PS does not notice that main screen is entered again. The log entry "... entering main screen ... " is missing.

My problems with powerscheduler:


1. PowerScheduler is shutting down while the TV Service is recording.


In MP log are entries "is any card recording? - false" but that´s wrong. I have a reording card.
MPFileWriter.log:
22-01-2007 18:55:07 Start Recording:'E:\Aufnahmen\Analog\Knight Rider-Das Vierte\Knight Rider-2007-01-22.mpg
(the show starts at 19:05 and ends at 20:15, I have 10min pre and 15min post recording time)

2. PowerScheduler doesn´t wake up system


Thanks Tobi (living in Bavaria!!)

Are you Guys using the new TV-server?
If Yes, then powerscheduler will not work, there is an update in progress for that.

OK, so PowerScheduler doesn´t work right now with the TV-Server, I understand....
When can we expect the mentioned update ?
