Manual power button AND auto-power-ON not working at the same time?

I’m just encountering the same issue on B01 Developer kit board as @Spenseryao (topic from: 19. Aug 2019.): cannot get to work BOTH: manual power button AND auto-power-ON at the same time.
Power button starts the Nano only if the “disable-power-on” jumper is set on J50. If no jumper: auto-start is there but power button is then useless…

Sorry if I missed the point of the accepted answer but how to make both features working at the same time ?

They can not work at same time, they can be chose by jumper.

Ok, that’s pitty… I think all (even thin-client-sized) PCs have auto-power-on option (settable in BIOS at least) , keeping both options…
