Need to solder laptop

post #1 of 4
Thread Starter 
So my laptop has a bad connection with the power cord. I know I am going to have to replace, or at least re-solder the DC to the motherboard. What is the best way to go about that?

I know I am going to need a soldering iron, but I'm not sure what is a good one and what else I would need. In some of the videos I watched, they had something to clean off the old solder before they put the new solder on.

I need some advice on good but inexpensive soldering irons and an overview on the process of soldering to a motherboard. Only thing I've ever soldered is wires. Thanks

you need either a desolderer, or desoldering tape.

The desolderer looks like (and basically is) a soldering gun with one on those baby snot remover bulbs on it.

If this is just a one off job though, I suggest desoldering tape. They got it at radio shack. You melt the solder with the iron, and apply the tape, which sucks it up. it's a bit like soldering kleenex. Much like kleenex it;s good for only one use, so you have to keep on cutting off and throwing away the used solder filled end.

Thanks, this is exactly the information I needed. Also, do you have any suggestions on a decent soldering iron?

The difference between a good one and a bad one is how fast they heat up, how long they last, whether the voltage is adjustable, and how well they hold heat. For a one off job i wouldn;t wworry too much. One thing I do, is soldering electronics requires a fine tip. Sometimes finer than is generally available on the less expensive irons. The tips are just hunks of iron, so I take a large nail, cut the head off, file the tip into a point, and use that. You can ut a bend in it if you need one for one thing.
