MacBook Pro 13” Retina (A1502, Build 12,1, Early 2015) will not power on with the battery connect to the logic board. To power on, I disconnect and perform a SMC reset with the battery disconnected. I can reattach the battery and it will run off battery power. When the the battery runs down and I plug mag power it does charge. I have been able to start “normally” and have performed apple hardware test - everything passed - no issues. The system profiler and used a battery health app - battery is good. Is there anything else i can do - other than replace the logic board?? Update (08/26/2018) no battery
with battery
Update (08/26/2018) with new battery
Instead of throwing the baby out of the bathwater, lets replace the bathwater instead ;-} You likely have a bad battery here. Battery health doesn’t really test the battery that well. Some of the cheaper batts fake it out.
