Hi guys, how are you all?
I have a MacBook 820-3330 with no power and need a little help please.
I have the original charger that supplies 16v but doesn't light up at all. I also have a USB C charger and converter that does light up and provides 19v.
Both give me a 12v on board and i have 3.3v.
I have 5 volt but its at 4.7v.
I have 1 voltage that isnt present but dont know if this comes after power on, this is q7220 pins 6,7,8 0v, doesnt seem to have any switching voltages going in from u7201.
I will give you some readings that I have and we can go from there.
Thanks in advance.
F9700 12v both sides
BKL_EN is 0v (not sure again if present before power on)
F7040/F7041 good
U6900 3.3 in and out
This is all i can think of atm.
Thank you John
