Re: Dell Precision 3510 completely dead
Yes, pin 1 and 2 as well as 3 & 4 are connected together.
From picture PU602 seems to be missing all the pins 2 to 5. Am guessing the burnt copper trace may have penetrated bottom layers, try cutting out the 'bulge' and see (if you are comfortable doing that. You'll also need to rebuild the other traces.
Maybe PU601 is on the other side of the board?
