Can't boot Imac 2011 without SMC reset

Hi,

I have an Imac 2011 that is perfectly working once booted up. Nevertheless it boots up only after a SMC reset, so I have to reset the SMC for each startup or each reboot.

I performed a hardware check, and everything seems ok. The EFI version should be "up to date".

I can’t figure what the problem is. I replaced the BR 2032 battery of the logic board, but that did not help.

Have you guys any other ideas what the problem might be?
