2. I use high-tech rosin core silver-bearing solder from Radioshack with diameter 0. 022 ( Catalog #: 64-013 ). I think popular rosin core solder will work just fine.
3. For removing solder around factor leads. I use Edsyn Soldapullt pump, model DS 017.
4. 99% isopropyl alcohol and tooth brush for cleaning the motherboard from flux.
5. A new DC power jack, you may find a cheap one on Ebay.

Commence desoldering routine with adding many new fresh solder to all three contacts. This will make old solder more flowable, easier to get rid of.

While heating one of the contacts, remove the solder from this contact using the desoldering pump. Repeat the same steps with all power jack contacts until you remove as much solder as possible.

Grab the power jack and carefully attempt removing it from the motherboard. In all likelihood you wouldn’t be competent to get rid of the power jack the first time because there will be many solder bridges left amid the contacts and traces on the motherboard.

Be mindful. Inside the positive hole there is a which connects the terminal on one side of the motherboard with the traces on the other side. Be mindful you’re removing the power jack with strength, you may pull the sleeve from the hole. You dont want to do that.

So, do not utilise any strength and assure the solder is melted when you’re removing the power jack. I hope you understand what Im discussing.

After the power jack is got rid of, clean all oxidized contacts with a knife.

Utilise a fresh coat of solder to all contacts on the power jack.

The power jack terminals will look dirty because of melted flux.

You may remove the flux using the tooth brush and alcohol. Its not essential but it will make your job looking clean.

Now you may install the power jack back on the motherboard. Put something underneath power jack so there is no gap amid the jack and the motherboard. Now you’re ready to solder the jack back in place.

Solder all power jack pins.

The occupation is done and the laptop DC power jack is limited. B-E-A-utiful!
Now just install the motherboard back into the laptop and you’re done.
