You sure that pad is gone? You've cleaned it up with flux and new solder and desoldering braid with a chisel tip? Maybe probe C102 to see where it goes and that will maybe help get you in the general area. Good luck! I wish I had a working PB100 - recapped my board which was a total PITA, recapped the screen etc and still have the dark blue screen argh...
Btw, those three mosfet are weird. I tested by removing them from the logic board (more than one logic) and they seem all shorted, i.e. the gates (G) are not discharged after touching with the finger.
I agree with 80sboy, if you are talking about the left pad.. this is connected to the right pad of C102, if you are talking about the right pad of C104, scratch the solder mask to get a clue.
