Any way to tell system to ignore certain devices when trying to sleep?

Sadly, ending all instances of dllhost.exe made no difference.

So the dllhost was a red herring.

I have no justifiable suggestions to make -
1 Are your Bios & your display driver up to date? They can have strange effects on behaviour.
2 Does SFC report any problems? S FC-DISM - TenForumsTutorials
Other than those wild goose chases, I'm out of ideas.

Best of luck,

Hello @imacken,

Firstly, I must apologise. I included the command powercfg /qh which was an error on my part and made the output far longer than it should have been.

I have looked through the results, and there is a LOT going on, but unfortunately I can NOT see anything specific to your problem!

Thanks guys, yes, BIOS, drivers all up to date - always! I put in a new motherboard - Z590 - over the weekend, and no changes of CPU/GPU etc. make any difference to this issue at all.
What I find surprising is that with all the knowledge here, at MS, Virpil etc. that I have consulted with, that no one is able to find a solution.
As I said above, I wasn't expecting a solution today, but I had hoped that maybe it was possible to have the devices overridden in powercfg, but apparently not.
So, thanks for your help, and if you have any more thoughts, please post.
(BTW, it's not just sleep the PC won't do when these devices are plugged, the display won't even go off!)
