NUC slight delay after not using? Seems like power save but everything power save is turned off.

[TheTransplant]

I have a NUC D34010WYK connected to a Planar touchscreen using Windows 10.  4 GB RAM, 60 GB SSD.  The touchscreen uses the native Windows 10 touch driver.

I have all power saving settings disables in the Windows - 10.  On high power, never turn off hard drive, displays, USB hubs, etc.

When I leave the screen for a while and then come back I have to touch and hold the screen for about a second for it to respond.  It is displaying fine, just needs this little wakeup touch.  Then all touches are immediate.  I hooked the touchscreen to another Windows 10 PC to test it and it doesn't do this.

I have the NUC plugged into a power sensing outlet and I hear it click when I first touch the screen after a while.  So the NUC is apparently going into some slightly powered down state despite all Windows settings being disabled.  Is there something in the bios or elsewhere that I could check for settings?  Thanks.

Do you have Monitor Sleep disabled as well?

I checked the bios.  There is nothing obvious in there that could be causing this problem.  I moved the touchscreen over to a windows 10 PC that I had running on my test bench and it works fine.  This is definitely something unique to the NUC.

To restate - I have disabled just about every power saving feature - monitor sleep, hard drive sleep, disabled USB power sleep, etc.  Yet the unit continues to have this slight 1-2 second delay when responding after being left for some period of time.

I am assuming that people have used NUCs in kiosk applications with touchscreens so wondering if this is unique to this particular model?  I guess I could get another NUC, different model, and try it?
