Hopefully, I will get my photos in here. (attached)
I'd like to repair this Dell XPS 710 motherboard, that I got not working.
I don't see any swollen caps, but these two mosfets were nuked.
They are cheap enough, so I ordered some from Digi-key.
My question is, am I right in assuming that these burned up from some direct short the previous owner did? They may be used as voltage regulators, but I may be way off with that idea.
Any ideas why these burned up and what I might do to prevent the next ones doing the same?
They are labeled as 79n03s and there are a few more pairs of them around the board. The others seem ok.
Thanks gents.
