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.
First thing I tried yeah, I tested a few and verified with a multi meter. It isn't that sadly :(
