I have a motherboard in a state where it won’t boot unless you pull and reinsert the cmos battery. After this it will boot exactly once.
It will also boot without issue if you don’t have a cmos battery at all. This is obviously not ideal.
I wonder if these issues are related? I purchased the motherboard second hand in this state about a year ago. So it is far too early for this update, but it remains a mystery.
I had something kiind of similar once, where it would only boot after trying to boot once, letting it run a bit in idle, and then rebooting where it would actually succeed. Turned out I forgot to put the clear cmos jumper back to neutral after i reset cmos.
So my best guess (other than new battery) is check the jumpers maybe
Y’know the setting in the bios where you can choose boot on power restore, stay off or last state? This relies on a capacitor on the motherboard near the bios battery to store the last state. This 5 cent capacitor can die and sometimes behave like you are saying. I had a repair guy fix it cheap and that server worked normally after that.

Have you tried putting in a new battery?
First thing I tried yeah, I tested a few and verified with a multi meter. It isn’t that sadly :(
Ain’t nobody got time for that
