Hello all,
I am continuing to trouble shoot motherboards. This time around I have found a bad QFN chip responsible for one of the power rails in this HP 15z-cd000. It is a DC-DC converter circuit. Dead short to ground through this IC. I'd like to replace it but the number on it is probably propiertary, it is marked something like AWV70H or possibly AWV709, or AWV7DH. I can't exactly tel but googling does not give me any results. I'd really love to be able to replace it as I think it's the only issue with this MB. I'm gonna try to dig through some junkboards and see if I can find it there too.
