hello i have a1534 after he DIY changing the battery for his macbook cant on,
but when i try put the charger can on but not recognise the battery.

after inspecting the motherboard i measure the battery terminal

SYS_DETECT_L OL
PPVBAT_G3H_CONN OL
i noticed that q6950 is burnt.

after i change q6950,q7155,u7100...

J6950
SMBUS_SMC_5_G3_SDA 0.589 3.29V
SYS_DETECT_L 0.506 0V
PPVBAT_G3H_CONN 0.686 8.59v
SMBUS_SMC_5_G3_SCL 0.609 3.28V
