How do I wake up my monitor from a scheduled task?

[keith_leitch]

I am hoping that one of you may have solved this problem, which is probably unique to HTPCs. When a recording (or any scheduled task) wakes the system, the monitor remains in powersave mode. support.microsoft.com/kb/283270 acknowledges that this is an FAQ to Microsoft, but they do not provide a solution; there merely state that this is "by design".

My problem is that I am trying to use graphrecorder to launch a task that will perform video capture. I want to do this automatically, like any other recording. Unfortunately, since the resume is automatic, the screen stays off and the capture fails. I have tried to simulate keypresses and mouse clicks at the start of my script, but these do not activate the screen the way that my actuail keyboard and mouse do.

I'm hoping the somebody knows of a program or command that I can launch at the start of my script, to switch the screen back on.

You might try HDMIOn, I used it at one time for something like this, but haven't for at least a couple of years. Here are a few links about the issue:

Thanks for the suggestion. I think this will much more efficiently solve the problem I have restoring HDMI audio after resuming the PC with the TV switched off. (Up until now, I have been setting and restoring a Catalyst profile: a tricky proposition, at best.)

Unfortunately, it does not solve the problem I raised in this thread. The monitor remains off. What I need is a software utility that duplicates whatever instruction is sent to the system or monitor when I press a key on my keyboard. I had thought that keyboard emulators would do this, but the three I have tried do not.

I was considering trying to use DEVCON to remove and restore the keyboard adapter. This seems extreme, but is the adapter likely to send a signal while being restored?

do a search on here for "fullresume.exe" and that should wake the pc by send the appropriate flags to windows directly..
[run first when coming back from standby]
if you can't find that, i can make ya one that provides those cmds from autoit..

it tells windows that the display is 'needed' and to wake it up..

Well, you ARE the most helpful person I've ever met...but I will try a few more things first, before imposing upon you.

I have just experimented with PVRx2, and it does not wake my screen when the system is awakened by a scheduled task (such as a recording). Very sad, but true. Do you think that they calls you are planning to make from AutoIT are similar?

EDIT: I found http://gbpvr.com/pmwiki/uploads/FAQ/FullResume.zip in http://gbpvr.com/pmwiki/pmwiki.php/FAQ/B...aticWakeup . It seems to work. You are a lifesaver (again).

NP...
once ya find the real windows commands, lots is possible...so simple really, but the explanations are so convoluted...
now this only wakes the screen once by resetting the windows sleep timers...

i'm not sure if it does the 'continuous' flag, without that you'd have to keep resetting timers or it will eventually go back to sleep..
with continuous set, it'll stay awake till you run it again without any other params..re-enabling the sleep timers..
so i put a 'wake' and 'sleep' params in to be able to tell it to resume sleep timers when i don't mind if it goes back to sleep..
i still have to test that feature as i had been just resetting timers every minute or so before..
it's already written so isn't much work now...lol

[pBS]

here's my little app...run with no params and it wakes display and system and keeps it on..
run with any params at all and it will exit and resume sleep timers..
eg:
keepwoke.exe
[wakes display]

keepwoke.exe exit
[resumes sleep timers so machine will sleep normally and exits program.]

to just wake display and exit:
keepwoke.exe
keepwoke.exe exit


you can check it with mce standby tool...[MST.exe]

i thought i could set it and exit, but program has to stay open to keep timers off..

how about this, i just make it keep display active while recording?
it already keeps system on, i can just add display...
wouldn't have to do anything but start it then..
[it would turn itself on/off when recording, which is presumably why system wakes anyways..]

Thanks for this. It seems to function much the same as fullresume.exe (which doesn't seem to time out). Keeping the video awake only during a recording is an interesting idea, but I don't think it will add value to my situation; as long as it comes on, which it does now, thanks to your help, things are sweet.
