This sounds like you did something more than just to replace the connector... Did you disconnect the BIOS battery? Still have the failure? Where do you see this "error 0x0284" if the laptop can't start?

Hallo,
The bios battery was disconnected for about 2 weeks before the new connector arrived. I try disconnect this battery again, but it still doesn't work. I really just resoldered the connector like I always do. I use iOS app "LenovoPCDDiagnostik" for listen the melody and this app say "error 0284 (TCG-compliant functionality-related error)."

I would try the usual, try other memories swap them or leave only one, I would start with this before making a storm in a glass of water
