Dell Inspiron 1420 AC Adapter power supply repairing guide

If you are experienced enough to do such repairs, following the suggestions below will assist you in repairing the power jack on a Dell laptop.
1. Remove the wire from both the laptop and the outlet.
2. Cut the wire at any point beyond the damaged area so that you can make a clean cut. It is best to leave at least a few millimeters between the damaged area and the cut to ensure that there is no damage to the wires you are going to reconnect.
3. Desolder the power jack from your motherboard that you have already taken out from the laptop. Both the motherboard and the Dell Inspiron 1420 AC Adapter jack have to be cleaned properly and then soldered again.
4. Carefully start to cut the outer plastic of both ends of the cut wire about a centimeter from the end. Do this gently as you do not want to cut the wires wrapped around the inner insulation. Remove the excess plastic.
5. Move the wrapped wires out of the way, and gently cut the inner insulating plastic only a few millimeters from the end. You will only need a tiny bit of exposed cord for this inner wire.
6. Hold the Dell ac adapter power jack and carefully remove from the motherboard. When the power jack is successfully removed, clean the oxidized contacts with a sharp metal object. Apply a coat of solder to the contacts. Clean the Dell Inspiron 1420 AC Adapter jack, and place the solders to all sides of the motherboard.
7. Secure the entire connection with a complete wrap of electrical tape, and test your connection.
