Fix an Apple Laptop Power Adapter

How to fix a new style Apple power adapter
1) Take two needle nose pliers, and use one to grab the brass tip. Then, insert one end of the other pliers into the rubber boot on the back. Now pull the two pliers apart, however, be careful, because the silver part is plastic. I damaged the end slightly, so, if you care about appearance, wrap the tips in a bit of electrical tape.
2) Now, slide the plastic end down to expose the interior of the plug unit.
3) Carefully slice the rubber boot, between the two wires, and on both sides Watch out for the magnet (ferrite) embedded in the boot. I cracked the mine, however, I did not know it was there. Do not worry if you break it, it serves to condition the line voltage, however, if you run it off clean power, like a UPS, you shouldn’t be too worried about it.
4) Now separate the boot from the plug assembly.
5) Cut the wires, and slide the ferrite out. Then strip the ends of the ground, and power. The black wrapped wire is the ground, and, the grey one is power.
6) Cut a bit of insulation from the long cord, and separate the outer ground from the fiber insulation, and, then separate out the power line. Then, cut the insulation with scissors.
7) Next, I found a rubber boot, which originally was part of a female rca cable. I then took out the rca plug, and internal wires. Now, slide the plastic protector, back on the wire. Then, slide the rubber boot on. And, finally slide the magnet back on.
8) Then solder the power, then the ground. I used .079cm rosin core solder. And, wrap each solder joint in electrical tape.
9) Place the ferrite between the 2 wires, and gently wrap the ends in electrical tape,
10) Slide the boot up to the power assembly, then slide the plastic protector. It will take a bit of force to get the plastic end to stay, so I put the plastic cap on the end, and pressed down on a table.
11) The finished product.
Many things can go wrong when working with power adapters, and what worked for me, may not work for you. You have to take the risk that it might damage your hardware, or yourself. If you use this howto, I cannot be held responsible for any property, or personal damage.
