Dear experts I recently received a MacBook Pro 2015 13” Early for motherboard repair. This board number is 820-4924. Owner connected system to low cost Chinese charger and MacBook turned off and does not want turn on. I found, than Q7130 is defective, so i replaced Q7130 and U7100. System turns on and work perfectly, But: When system is turned off and connect charger, the system does not boot. I have to press the power button to turn on the computerWhen system is turned on and connect MagSafe charger, computer does not want charge. In manager it shows me than charger is connected but does not charge. So i replaced Q7155, D7105, R7105 and U7100 one more time but system does not want charge. Any idea where can be problem? Thanks @refectio
It sounds like a Smc issue, already checked PP3V42_G3H_SMBUS_SMC_5 ? As a rule of thumb I prefer to replace the ISL and the two mosfets at once or one runs the risk the faulty part burns the good one in a never ending loop. @refectio
