[/img][/img]Hi i hope some one can give me info about this transistor i belive its a Mosfet. i can see 403MJ. But i dont now what type of transistor it is. its connected directly to the power bord on the dc jack 19 volt. I have look ower internet and cant find this 403MJ for HP mother bord (6050A2892401-MB-A01) I whill send one more picture but this is for HP840.
but they have nearly the same but they use 403Tj for hp 840. And 850G3 they use 403MJ. And i need to now witch transistor for the 850G3 403Mj
