Mac does not start unless battery is disconnected and reconnected

My Mac currently won't boot, it won't respond to anything even when I plug it into the charger. The problem is solved when I open it, disconnect the battery from the logic board and reconnect it. Then it works for some time, but at the latest after 1-2 days the problem comes again. I can't unscrew the device and reconnect the battery every time. The battery itself seems to be in good condition, Coconut Battery shows good values, it also lasts a long time.

Please help me, do you think the problem is with the battery or the motherboard?

Kind regards

After resetting SMC restart the system enter into the onboard diagnostics to see if something pops. If that doesn’t help focus things you’ll need to do a good inspection of both sides of the logic board looking for stains or burnt components.

I tried, but when entering diagnosis mode, it keeps saying that a diagnosis is not possible as the an error occurred, try again...

@vegotech - Ouch! Sadly the logic board has an issue. If you don’t have the skills or tools it maybe best to seek either an independent Mac repair person or Apple.

Are you 100% sure?

@vegotech - As best as I can be from years of experience fixing Mac systems. The onboard diagnostics is built into the systems firmware. So it is at the lowest level, below the OS so if it is ha I let’s deep!
