I am a novice to repairing hardware but have been expanding my skills recently... tried repairing a broken dc jack on my mom's Dell Inspiron 1501 laptop. I had no previous soldering experience but thought I'd done enough research and watched enough YouTube videos to get the gist... problem is I tried out 3 different soldering irons and couldn't really make a dent in getting the existing soldering off of the component and board! The 3rd iron I used was an Elenco 40-watt soldering station, temp turned to max. I tried soldering wick, Chipquick, adding new solder... you name it I tried it. Nothing would get this stuff to budge like in any video I'd watched. What am I missing? In doing research for a better iron I have only seen suggestions to NOT go over 40 watts... yet this didn't do the trick. What gives? I did eventually get the solder off and attempted to solder on a replacement jack, but when I plugged in the laptop it tripped the circuit on the AC adapter so obviously there's a bad connection. I threw in the towel and ordered a replacement board off of Ebay which ended up having a bad RAM socket (ARGH!!!). I'm now mustering the courage to attempt a repair of the original board (if it's even still good at this point) but I don't know where to go from here regarding the right soldering iron, solder, etc. Any tips or advice for working on this type of board? I did read something about motherboards with an Intel Pentium 4 CPU or after greatly affecting heat dissipation or something but I did see guys online successfully doing this like it was cake.
