Help with a macbook A1398, it does not turn on and does not charge, green LED and changes to orange, it only turns on counting 8 seconds and connecting the charger, but when you disconnect the charger it turns off, it does not show an icon or percentage of charge, it does not show a charging cycle the battery, I am repairing it, I measured all the voltages and they are all present except PP5V_S0 and P5V3V3_S4_EN, only those 2 voltages are not present, I have tried to repair but I have not been able to, I do not have voltages on the fans. Please who can help me.
