Can i send Hp part no. 519329-003 Laptop adapter common fault and circuit Diagran
 

I understand that you need the diagram. perhaps it is better that a technically qualified service person handles it, instead of us at user level, even if e are qualified engineers, or would be engineers.

In most cases we can open, but there is risk in handling, and getting spares , if able to diagnose.

for general academic interest, it is as good as any other smps designed using standard switcher chips.
