Windows 7: Need help with powercfg -requestsoverride

Good question ...
Yea, skip my driver override suggestion for what you want to do, and see how it works for you.

The systems i've worked on, i was trying to fix PC sleep issues, not just monitor sleep.

Still no go.

I tried "\Device...mpc-hc.exe". I even tried "C:\Program Files...mpc.exe"

I just don't understand how this works.

In my case, mpc.exe is still listed as preventing display sleep and does indeed prevent display sleep.

It could be the way MPC is programmed.
You might ask on the MPC forum (if they have one), or check their documentation.

If I am watching a movie, i would not want the monitor to go to sleep, while the movie is playing...

Actually, GokAy got the scenario exactly right. Bedroom, bedtime, sound, but no light.

As far as MPC is concerned, yes, the program itself tells windows not to sleep the monitor while running. I've got other programs that make the same statement to windows.

It's my understanding that powercfg -requests will show you the programs that have that coding (because the statement will show up under display, or under system if it is meant to prevent the entire PC from sleeping).

It is my understanding that in the world of preventing sleeping, it is ultimately in control of windows, regardless of what the programmers intended.

It is also my understanding that powercfg gives this power to the admin of the pc.

Perhaps my understanding is incorrect and it is possible that there is nothing the OS can do about it and therefore nothing the admin can do.

If you are still seeing the request, maybe to override was not entered correctly ???
When you entered the entire command did you manually type it in, or did you copy from the requests CMD window, and paste with that for the override ?
I copy the text from the CMD window, i probably would make a typo trying to manually key it.

Regarding "Actually, GokAy got the scenario exactly right. Bedroom, bedtime, sound, but no light."
If the real problem is the light from the display, you could try using a screen saver of Blank.
That would not turn off the display, but might be a workaround that would be better for you ???

My setup is pretty convoluted with multiple/multi-user/multi-boot PCs, multiple displays, multiple audio devices, KVM, multi keyboards, multi mice ...
Some of the audio output devices use the monitor speakers, if and when wanted.
If the monitor turns off, and that is also the current audio output device, audio would also be lost.
I don't want to lose audio or video, anytime Media is playing, for any user, using any current config choices ...

I understand why a media player, any media player, would instruct windows not to sleep the display and not to invoke the screensaver while "I'm" playing. It's normally a feature rather than a bug.

It was my understanding that even though the software instructs windows, it is ultimately up to windows to obey or not obey this request.

It was also my belief that windows passes this control to the admin in the form of a program called powercfg.

Apparently I'm wrong about this and it is the program that maintains ultimate authority and windows is harmless to do anything about it.

I'm confident that in certain situations powercfg does have control over specific power management features, but in other situations, powercfg does not.

Dave, scr will carry the exact same problem as monitor sleep.
I've typed the attempt dozens of times. Surely at least one of those times I typed it correctly. I also took a snapshot of the command that was typed and included it in the first post. You provided an adjusted suggestion. If anyone sees anything wrong with the code, please let me know.

Just to be clear on what I'm trying to accomplish ...

I do not want the monitor to fall asleep. As a matter of fact, in power options I have the monitor falling asleep set to never.

I do however, have the ability to execute a command that specifically puts the monitor to sleep. If MPC is running (but minimized so there is nothing actually changing on the desktop), the monitor will go to sleep and then pop right back awake.

After researching, I found out that the reason this was happening was because of the setting in powercfg where mpc prevents the monitor from going to sleep.

The objective of this thread was to understand how to remove mpc from under the "display" section of powercfg.
