Hello,
the first problem of this board was no green light (missing PP3V42_G3H)
I solved this issue by fixing burned R7080 (corrosion).
So now I have all power rails ON on the board and 590mA on power supply but still no fan.
I have PP5V_S0 ON but the issue is that I have 0 V to the PWM from SMC to control fan speed.
So I booted the board in SMC bypass mode and now I have a fan speed with max speed which is normal.
What can be the issue? why the board seems to boot normaly without fan spin ?
thx,
Vincent
