MacBook Pro 13" 2015 A1502 no PPBUS_G3H green orange light but no fan
I have no fan / no power on my MacBook Pro. My MagSafe charger LED is either Orange or Green, but the system doesn't power up.
I don't have PPBUS_G3H. Does someone have an idea why?
U7100:
- Pin 2 = 16V
- 17-18 = 4.2Ω (normal)
- 27.28 = 20Ω (normal )
F7140 = resistance to ground 1,4Ω ??
UPDATE:
PPBUS_S5_HS_COMPUTING is shorted to ground. Pin 2 of C7316 getting hot.
Update (11/22/2017)
The HS Line is shorted to ground. I Cent do anything beacuase of The hole in Board.
Questa è una buona domanda?

Did you check the fuse link? {F7040}

You mean F7140?? How can i test it? What specification has it?

I think he is referring to the PPBUS_G3H fuse. Measure both sides of the fuse, one side is for the system and the other side is more closer for the DC-in jack.
