Macbook Pro Retina 820-3476 not charging


New member
The computer turns on but no charge, the customer tried to resold the power supply cable by inverting the wires.

I do not usually repair mac cards, it's for a friend. I usually repair iphone cards.

i would like to know if there is any reverse gate protection. i checked the fuse but are ok , and i tried a new dc in board

As per schematic, Q7180 works as Reverse-Current Protection, apart of Inrush Limiter.
D7005 protects 3V42 power supply too.
Thanks God, something get burnt in such case, and we can pay the meal :)

Start checking voltages at L7095 and U7100.

I'll explain I have to make 1 order from mouser and I would like to make one only as I pay € 20 shipping from USA to Italy, so I would like to take extra components to make sure I have everything I can
