Locate the solder joint on the top portion of the logic board. It will appear as a shiny silver bead of metal.
Place a piece of solder wick on top of the solder.
To desolder the connection, very carefully place the tip of the soldering iron on top of the solder wick. Hold it steady until the solder is soaked up into the solder wick.
The soldering iron will damage circuitry if held down for too long.
Cut off the used solder wick with pliers and repeat above steps if any solder remains.
