Repair Laptop Battery Chargers
A laptop battery charger often becomes worn because it is constantly being pulled and plugged in and out of the laptop and an electric outlet. Without the charger, you won't be able to use the laptop when the battery dies. Laptop battery charger repair can be done if you are adept in repairing computer parts.
Instructions
1. Shut down the computer and pull out the charger from the laptop and the electric outlet.
2. Plug the soldering iron in an electric outlet and turn it on. Allow it to reach 80 degrees Celsius (176 degrees Fahrenheit).
3. Remove the screws that hold the base of the computer to the chassis of the computer. Use a screwdriver to take out the screws. Mark each screw so you know exactly where to put them back.
4. Remove the laptop motherboard and carefully blow off any dust. Place the motherboard on an antistatic mat.
5. Look for the power jack, which is usually to be found at top right hand corner of the motherboard. It is a small, silver-color piece. Check if the soldering on the jack is broken or misaligned.
6. Place the de-soldering pump on the soldering and start removing all the old solder by holding the iron on the solder until it runs into the pump.
7. Detach the contacts from the jack on the motherboard by removing the old solder as you did in Step 6. Once all the solder is removed, gently remove the jack off from the motherboard.
8. Observe the receptacle on the circuit board that should be clearly visible with the jack out of the way. Remove any flux, debris or dirt around the receptacle using a small brush or a toothbrush.
9. Clean out the jack using a small eyeglass screwdriver or a tiny penknife. Solder the contacts using as little solder as possible.
10. Solder the input jack back on to the motherboard. Resolder any contacts you have unsoldered. When the solder is dry, re-assemble the computer base onto the chassis placing each screw right where it was removed.
