Any suggestions for removing the resin glue? Second, rotate the screen so you can access screw holes. For people having trouble getting the solder to melt, the jack itself can act like a large heatsink, drawing all the heat away from the joint, so it can take a bit of time for the solder to melt, far longer than the seconds some sites suggest it will. Do you recall whether the circuit board was black before you unsoldered the jack, or after? Then, I took the docking station luckily it is small , connected the PA to it, and docked the laptop. It sounds archaic but wiggle it.
