Resposta para "Battery not detected, won't charge; strange connector on logic board?"Guys, I found another solution! I had the same problem after replacing the battery with a new one (Battery Installed: No). I tried everything that was in this topic, except for the new i6259 chip. The first thing that partially helped me was the second version of the solution from XnriquX @xnriqux. My macbook pro mid 2015 started to work without charging, but the fans began to go crazy and the charging LED on the connector turned off. But if you reset the SMC, then the fans and the charging LED start working fine, but the macbook stops working again without charging. But in the end, the solution turned out to be simple - you just need to adjust the contacts on the battery connector to the motherboard, that is, in this connector (which comes from the battery) the copper mustache is not pressed tightly, which is why there is no contact . You must press the mustache gently, preferably with a needle. It helped me and my macbook began to see the battery and work as expected!
