After exchange power socket, motherboard dead, not charging battery...
I look all motherboard dont see any damage , broken components..
no shorts on coils
20V is on the board , 3,3v , 5v missing

2-5pins -20v
17 pin ld0 - 0v (56,7kohm)
exchange AWV nothing change
removing kbc still dont have ld0

в разъеме есть id, должно замыкать на землю.

А 5v куда пропало? Начните с этого. Без измерений никто гадать не будет, почему оно дэд.
