Step 1: Issues

Getting to school and needing a computer, I set to the task of figuring out exactly what was wrong and how to fix it. My first impressions was that there was absolutely no solder on either the cables that were ripped from the back of the plug, or the plug.

Step 2: Not So Simple

No stranger to solder, I tried soldering wires straight to the plug to no avail. No matter how hot I got the plug, it was too polished and the solder just wouldn't stick. It was more difficult then trying to solder something to the bottom of a can of soda.

Step 3: Figuring Out Connections

So the first thing after cutting the new cable (which was left over from some old component), was to figure out which prongs of the plug went to which wires.

Step 4: One Last Thing Before We Put Everything Together..

Right before I started soldering the cables together, I noticed that if I'd kept going, the power adapter would have had a large exposed side. To keep this from happening, I decided to drill a hole right in the center of the faceplate for the adapter.

Step 5: Putting Everything Together

Now that everything was ready, it was just a matter of getting everything set up, soldered and adding finishing touches.

Step 6: Wrapping Up

Snap the faceplate back in place and enjoy your new plug. If your plug doesn't have a snap, a little extra tape on the outside will work just fine. I did my first power check not plugged into my computer. I plugged it into the wall, and ensured the "I'm plugged in correctly" light came on.

Can you wrap a power cord around a power adapter?

Never wrap the power cord around the power adapter or any other object as this could cause the internal wires to break. Broken wires can short circuit both the power adapter and your notebook's internal power supply. Broken wires can shock anyone who touches the cord, and might also present a fire hazard.

Step 1: Before You Begin

I recommend that you check if it's really a poor or intermittent connection that causes your situation: Therefore you twist (maybe pull or push the cable inward or outward to/from the adapter) and see if the connection problem is solved.

Step 2: Open Up the Melted Case

In my opinion this is the hardest and most dangerous part. These days they melt the casing together. Which means that there are no screws or bolts to open up the case clean and unscratched.

Step 3: Clean Up Both Shells

Take out the circuit. Clean up the edges of both shells so that they fit together without any pressure (we need this in a further stage). In my case the white wire is Vc (output voltage) and the 'black' wire is the Ground. Remember this/write down your situation (we need this in a further stage as well).

Step 5: Finished!

So you'll have your own repaired and perfectly functioning adapter back! Enjoy your work and no twisting needed!
