This is strange. For years I have this ASUS Z170-A set to power on after a power failure. Why? Because it is on a Power Station with a master switch. After I shut down I turn off the Power Station. When I want to power on again I turn on the Power Station and all powers on OK.
All of a sudden I have to now turn on the computer with the case switch and then it goes into BIOS. I see the issue as somehow it is now set to stay off when power returns....not sure how that ever changed but when I go into BIOS and tell it to power on after power comes back and tell it to save that setting it looks OK.
However when I power on again the next day, I see it is back to stay off which is what the BIOS says again. What would keep this from saving this 1 setting or what would change it?
I do not believe it is a CMOS battery as all the other settings are OK.

Thank you for any suggestions!
