I have a dell inspiron n5010. The dc jack on it does not work, the middle pin is broken off. I have a new dc jack for my laptop , but I am not sure how to solder it on. I looked on the internet to see if I could get instructions on how to do it for my laptop, but I couldnt find any. Can any of you give me some instructions, or maybe point me to a video of how to do it?
