A common issue with laptops is that the power connector is susceptible to frequent tugs and pulls in opposing directions. This creates strain on the soldered power connectors on the motherboard and will eventually fail rendering the laptop useless, until repaired. You will need to disassemble the entire laptop to expose and remove the motherboard; this re-soldering process will take approximately 2 hours. Start to desolder the existing power connector by adding fresh solder to melt down the existing solder to be removed with a desoldering pump. Repeat this process with the other power jacks on the motherboard.

At this point pull, ever so slightly, on the power jack to determine if all of the solder has been removed. It is typical that not all of the solder was removed, so you may need to simultaneously pull the jack and heat the contact points to loosen the solder and remove the jack. After the jack has been removed, clean the leads with a small knife to get rid of any corrosion or dirt that may have built up on it. Next you will need to apply fresh solder to the contacts of the jack to prepare it for re-entry to the motherboard.

Before the jack can be placed on the motherboard, the board should be cleared of flux, or the small left-overs from the solder. With a small toothbrush and a light amount of rubbing alcohol gently rub the surface of the motherboard clean of the flux. After, apply a small fresh coat of solder to the contact points on the motherboard. Be sure to coat both sides; above and below for best results. Place something under the motherboard as you re-solder the jack into place; this will keep the motherboard level. Apply solder to each contact and you have finished. Repeat these steps in reverse to finish your project.
