Macbook Air 820-00165 Charging Issue

[Instafixx]

This Macbook had came in before for some repair long time back.

it came back a couple of times for not charging issue.It charges from a knock off charger but not from a Genuine charger.
I had replaced D7005 and R7006/R7005. i dont remember if i had replaced Q7180 or not.

How can i check and be sure ?

Post PPBUS_G3H and 3V42_G3H with original charger( when problem appears).
Also check DCIN at same time.

I had checked.
No voltage

That is because original charger is smart enough to detect input leakage.
You may have problems with R/D7012, or Q7180.
