Subject: H170A-X1/3.1 boots to BIOS sometimes

cybermcm, I finally got my H110 chipset PC (the new DeskMini 110W) to start into the UEFI after a power reset.
You know the configuration, Wake on LAN enabled in the UEFI and in the Intel network driver. Yes I did not have Reduce Link Speed checked. I had Windows 10 fast startup unchecked, and cold booted a few times to be sure it was not active. I had Fast Boot set to Ultra Fast, the only Fast Boot setting I had available in the UEFI of this board, the H110M-STX, since I have a UEFI booting Windows 10 installation, installed with CSM disabled.
But what was it, apparently, that caused the cold boot into the UEFI after a power reset?
Something I forgot to ask you about, but tried it anyway. The Deep Sleep option in the UEFI.
Deep Sleep is set to Disabled by default. Frankly, I don't know what power state the board is in when Deep Sleep is Disabled.
I figured you might have set Deep Sleep to S5, in order to get WOL working. BTW, you are correct about Windows fast startup being required to be not enabled (unchecked) in order for WOL to work, that is a known requirement given what I read about it, in multiple places.
So with Deep Sleep set to S5, and the rest of the configuration above, I experienced the cold boot into the UEFI.
I haven't tried to see if it will do it again, and that was NOT on a WOL event. I actually forgot I had that PC ready to test this, and started it up since it has a UEFI update that I wanted to apply.
Also, to be very clear, that was after I had done a power reset on that PC, which did NOT start into the UEFI when I applied power to the PC again. I happened when I powered the PC on manually. Regardless, I think it may be significant in this situation. I wanted to get this out to you ASAP.
The question that remains is, what did you have Deep Sleep set to in your UEFI?
