    I read it's easier to put more solder on them at first. It makes the flow easier and therefore makes it easier to remove. I'll try that later. I'm just scared I'm going to burn the motherboard to much and render it useless

    Got a hot air gun? If not then a blow dryer for hair sometimes does the trick.

    Adding more solder is known to help yes although I havent tried that, you can also get desoldering wick stuff but I havent tried that either.

    with the dremel im jsut trying to get at the idea that if you cant solder off the contacts, maybe you can cut off the top part(with the jack on it) and then there will be less material to heat up for the soldering iron?

    hey JDM
    i have already remplaced a DC plug its not really hard but it should not be to hot to damaging the motherboard. to desolder the old plug use a sommething like this 1-5M-Length-3mm-Width-font-b-Braided-b-font-font-b-Copper-b-font-font.jpg
    you put the wire on the solder and you put the soldering iron on the wire , the solder will be absorbed in the wire.

    Thanks man I'll probably try that does the port look like it's going to work? That on in the middle looks burnt I hope it didn't mess up the motherboard

    Yes in the tin soldering there a cleaner , to clean the surface for a better grip. It's the brown around the solder.

    You can see where I tried to use the solder gun to heat up the solder looks horrible :(.. I was talking about the gaping black hole uploadfromtaptalk1400635248518.jpg

    I think that's called rosin, and it helps the solder stay liquid IIRC. This is why putting more solder on the iron first (Most comes with a rosin core these days) helps, the rosin gets on the preexisting solder which can help it melt. At least how I understand it.

    Also, you may have to hold in on the joint for a while if it hasn't been soldered in a while. Just redid my drugstore cheapo headphones (Can't find the same style any more) for the 4th time, took a good 3 minutes of about 30 second heat applications for each joint to come free.

    Look at the picture I just uploaded. I think I'm going to wait till I get some of the desolder wire before I touch it again.. I hope I didn't fk it up.. There's literally like no visible solder

    Alright with my 60 Watt gun I'm going to get it heated up and sit it on the metal prongs that belong to the DC port. Going to see if that sends enough heat through.

    Maybe it's possible that the heat is dissipating through the jack?

    I can say the 60 Watt is too hot for the solder I have

    I'm not touching this till I get solder wire.. Might have messed up..... :<

    What exactly was wrong with the DC jack?

    With my old Presario R3000 (Top-of-the-line laptop from the early '00s) the jack had corrosion on it but I was able to scrape some off (After the jack was removed) which worked for awhile until I got a replacement jack.

    It's broke.. Wore out junk. Already ordered replacement just having a bitch time it with it and it's making me mad.

    Alright I just learned a lot of little things from an Electrical Engineer thanks via YouTube and I was doing a lot wrong. I am going to need the cable that absorbs the solder. That's mainly it. And I learned how to properly solder.. Going to get some better quality solder for this project. It's gonna be done right no matter what.

    OK I even bought solder remover the copper braided wire. It won't even pull the solder off
