Hi all! I have an old HP Probook 4410s which audio port, the one that carries the signal out and where the headphones go connected has been broken. I think the problem relies in the central pin that is in the rear zone of the port, that little piece of metal has been broken leaving the port unusable. I'm actually not using this laptop and since it has many other hardware relate problems I decided to see if it was possible to replace that part by myself.
 
I started disassembling all till leaving the motherboard free, but, when I try to remove the little port from his soldering points with my soldering iron (30 w) it doesn't move in any way, I tried putting some soldering flux in the area but it's useless, this is how it looks:
 
 

 

 
The solder is very strong and I'm not sure about using a more powerful soldering iron, so what do you think, should I use a different soldering iron or an even more capable tool like a heat gun?
 
Oh, another question... The new substitute port could be extracted from any other laptop or it has to be one from the same model? Thanks!
