My fellow Greek..
Remove keyboard and with a pen or something similar made from plastic push on various places on motherboard around the BIOS battery.Maybe pusing somewhere makes it start working again.....
It has happened to me two times with different laptops and they all had that problem ..I guess there is a problem with motheboard tracks but I'm not sure..

Be saying "different laptops" I mean same brand and model but not the same laptop..

Pressure doesn't seem to solve the problem . I tried reflowing 2nd time with no result ... Maybe I'll try a reball

If reflow didn't fix, it reballing isn't going to do anything.
