Win10 PVR won't sleep after recording(s)

[philb49]

I have recently installed NextPVR 3.9.2 on a clean install of Win10. I have a Hauppauge 2200 tuner card on an ASRock mobo, I5 with 4 gig of ram. Nothing special. NextPVR works a treat and I'd like to use this pc as a standalone PVR.

I schedule recordings from the guide and the pc will wake from sleep as expected and record. I realise NextPVR wakes up the host machine but is not responsible for putting the machine to sleep after the recordings, having researched and discovered that in the forum.

In Win10 Power Settings I have set the monitor to sleep after 10 and the pc to sleep after 15 minutes. The monitor sleeps ok but the pc remains on despite the recordings finishing hours prior. I have disabled wake in the network card properties, likewise the kb and mouse.

NextPVR is the only program installed. Is there something specific in Win10 I am missing here? Is there a program which may "override" Win10 power settings.

Thanks

Run the command powercfg -requests to see what might be keeping it awake. Perhaps you have your machine set to stay awake on network activity (not the same as WOL)

Thanks for that. I have run that command on XP (I think) and Win7 machines in the past to sort power issues out. Here's what it returned:

C:\WINDOWS\system32>powercfg -requests
DISPLAY:
None.
SYSTEM:
[DRIVER] \FileSystem\srvnet
An active remote client has recently sent requests to this machine.
AWAYMODE:
None.
EXECUTION:
None.
PERFBOOST:
None.
ACTIVELOCKSCREEN:
None.
C:\WINDOWS\system32>

Unfortunately I'm not sure what the active remote client is and how it is interfering with the sleep process.

Many years ago when I had a similar problem I watched task manager and noticed that it was almost impossible to go 15-20 minutes without windows doing something. The solution for me back then was to sleep after 5 minutes which has worked for some years.

Another similar problem was a desktop PC kept waking up just after being put to sleep. It was being woken by something unknown on the network so the solution was to set the adaptor to only wake on magic packet. However if you have disabled WOL than that should not happen.

Also under Advanced Power Settings under "Multimedia Settings" under "When Sharing Media" changing to "Allow computer to sleep" may or may not help!!

I set some random recordings overnight and when I woke up this morning (da-da-da-dum) the machine was not running. This is encouraging!

I'll check later today if the recordings indeed worked and report back.

Thanks

I've actually had this problem for a long time, but it's intermittent. The only pattern I've noticed is it seems to happen more often when a show ends on the half hour than when it ends on the hour.
As with Philb49, Powercfg shows nothing is requesting the system to stay awake. But only stopping the NPVR service and restarting it prevents the system from coming immediately out of powersave after it goes to sleep, when it does decided to happen.

I never bothered reporting it because nobody else seemed to have the issue and there was no clear reproduction or cause.

I have discovered that the pc actually shuts down after the recordings have finished, but some time afterwards the 15 minutes or so I set in Power Management. Test recordings I have made during the day indicate it it could be 2 hours or more.

It's frustrating, but I think Windows10 is working against us rather than for.

I'm determined to get to the bottom of this and when I sort it out you will be the first to know.

After some research, I found a possible solution to Win10 preventing machines from going to sleep. So I ran this as admin:

powercfg /requestsoverride driver srvnet system

That seemed to fix the sleep problem, but when I recorded a program I could actually monitor in real time, the machine shut down as per the power settings menu, 15 minutes, but then restarted shortly afterwards on its own throwing up a NextPVR dialog saying the program was "interrupted". HuH? And now the machine stays on.

Now I have finally worked out how to add attachments, here they are:

Thanks again

No they aren't.... How do I do this??

I can't see anything in the log that you attached that suggest that NextPVR is causing the wakeup. There are messages in nrecord.log to show that NextPVR is aware that the system is waking but not because NextPVR asked for a wake ...
