I have Win 8.1 machine that I use exclusively as a file server - no other duties. I therefore kept the installations of programs/utilities to a minimum, i. e. MyMovies, FlexRAID-F, snapRAID and Hard Drive Sentinel.

I have set the machine to go to sleep, then hibernate after 10 / 15 minutes of idle. However, it rarely ever does it and simply stays on. The Task
Manager does not show any applications running. I usually wake up the machine through WOL (magic packet).


How can I find out what is keeping the server awake?

Make sure 'Only allow a magic packet to wake the computer' is checked in NIC properties. It is unchecked by default in 8/8.1.

Yep, thanks, I have done this already.
(I had learned this in an earlier build )

Is Hard Drive Sentinel querying SMART often and keeping the server awake?

Is Hard Drive Sentinel querying SMART often and keeping the server awake?

I have HDS installed with its default values. I had done the same in an earlier build (Win7), in which I did not have the not-sleep issue.

I just looked through HDS's settings for a SMART query setting. I found under Advanced Options - Detection frequency. It is set to 5 min (default). I now changed it to 30 min (which is longer than the time I have set for sleep/hibernation).

Thanks for the tip!

Here are the relevant parts of the report:

a)
System Availability Requests:System Required Request
The program has made a request to prevent the system from automatically entering sleep.

Requesting Process \Device\HarddiskVolume18\Program Files\Windows Media Player\wmpnetwk.exe



=> based on that I have now changed the Power Options - Multimedia settings - When sharing media to "Allow the computer to sleep" (was "Prevent idling to sleep)


b)
System Availability Requests:System Required Request
The device or driver has made a request to prevent the system from automatically entering sleep.
Driver Name \FileSystem\srvnet

(update: while I am writing this post, the server has gone to sleep - yeah! So one of the 2 changes (WMP or HDS) must have done the trick. Now I need to figure out which one it is. Furthermore, will the server still stay awake when I access media files....)

Thanks guys!

There maybe an easier way to do this but...

Once I opened Task Manager and stretch it all the way across the screen and let it show me the cpu historygram, and notice there is a small cpu bump every 10 minutes, very consistent. Next time I waited for this bump and quickly switched to the Task screen with the cpu% sorted by usage and noted what processes was the culprit.

I have not tried this, but this approach makes sense to me. I will keep this in my 'mental toolbox' for the next troubleshooting endeavor.

After some more testing, this one seemed to be the culprit.

Again, thanks everybody for your help! Much appreciated!
