Black screen after resuming from standby

[psicotron3]

This problem is even worst now with PVRX2. After a schedulled resume PVRX2 gives an error message stating that the system don´t support VMR9.

I can playback an mpg via wmplayer and wake.cmd to make the pc go into fullpower state, but that´s really ugly

Maybe sub could add an option to make PVRX2 send Windows the "message" to "finish" the system wake up (Powering on monitor and other devices) before starting the interface.

I just saw a post on HIP forums by ricky, that may help:

Here is the ms site link:

http://www.microsoft.com/technet/scriptc...x?mfr=true

And his post:
"From what i understand reading that page that i linked to, any scheduled task will trigger an 'event 18 - resume automatic'.

then once in this power state, any remote button pressed when using the ehome driver will trigger a 'event 7 - resume from suspend'

but using the alternative driver doesnt trigger this 'event 7'

If hip doesnt contain any commands which would trigger this, is it possible that a 'system resume' system key can be added which would generate this 'event 7'?"

Back then btmi couldn´t help him

But I still have hope

I had the same problem where an automatic resume wouldn't turn the video on and PVRX2 would then generate the "no VMR9 support" error. As a workaround I wrote a small command line utility which when run just tells Windows that the display is required (using SetThreadExecutionState). I run it from another application whenever Windows resumes automatically.

I've attached the exe if anybody wants to try using it from wake.cmd or calling it through a remote key.

Thanks. I´ll try it and post the results.

look for kb923232 at microsoft. it may help.

Thanks but that's not quite the same situation we have. In our situation the system still responds fine when it resumes but (by design) if it resumes automatically (like for a scheduled task) rather than through user interaction (like pressing the power button) Windows assumes the user isn't present so doesn't turn the video on. You have to press a key or move the mouse to get the video to come on.

seems like that's no workaround but the only clean & workable way (designed by microsoft) beyond a hack like my "play a vid" workaround from above
i've searched a way to send a system broadcast for WM_POWERBROADCAST messages (needless to say there ain't none) but somehow i've missed (or ignored?) SetThreadExecutionState
out of curiosity: which es_flags did you use? the ES_DISPLAY_REQUIRED?
seems like it's possible to call that from an autoit script (or other script languages as well?) using:

Code:

DllCall ("kernel32.dll","long","SetThreadExecutionState","long",0x00000002)

Correct.

That's quite possible and would probably be a better solution if you were already using an autoit scripts. I haven't tried it though.

I also tried sending the WM_POWERBROADCAST messages as well as a few other things before I finally found this solution! I was really getting peeved at having to get up off the sofa to wiggle the mouse and click on "OK" for the VMR9 error before I could do anything else!

Let us know if the autoit script works.

It worked.
Running from wake.cmd it turnned on the monitor. Now I´ll put it inside the batch file I use to call PVRX2, so the monitor will be turnned on only when it´s needed.

Thank you.

Let us know if the autoit script works.

i've added the code snip from my previous post to gEd's startGBPVR au3 script (the part where he checks for PBT_APMRESUMESUSPEND) & done a quick test. it works like a charm

It worked.
Running from wake.cmd it turnned on the monitor.

did you use the attached FullResume.exe? or did you manage to call the dll from batch? if the later i'd like to know how you did it
