Introduction

As you can see by the photos, I took a broken and otherwise useless magsafe end and made a splice. After a resolder, the LED shows the computer charging.

  • This is a hyper extended end of a magsafe. It is no longer working due to the wire having pulled apart.

  • Use wire cutters to cut the wire of the magsafe some distance back from the magnetic end. I cut about 4 inches back. You can get much closer like maybe an inch, as you will see in the next step.

  • I used a utility knife to cut the nice white cover off the tiny printed circuit board. There is a molded plastic cover similar to hot glue which had to be stripped off the PCB.

Image 1/1: 2.) The interior wire, which is coated in white should be soldered on a square metal plate about one eighth inch square.  This plate is opposite a small chip for reference.
  • 1.) Take the good end of the existing wire and strip it.

  • 2.) The interior wire, which is coated in white should be soldered on a square metal plate about one eighth inch square. This plate is opposite a small chip for reference.

  • 3.) The braided wire coats the white interior wire, and is wrapped around it in two different directions. This wire should be peeled off and then twisted together.

  • 4.) Then solder it in place opposite the chip and the other wire.

  • Plug in wall outlet and install on computer to test.

Thanks a lot for the tutorial, worked like a charm and the result is quite clean too. You made me save 80€!

Works but looks like !@#$.

If it looks stupid, but it works, then it's not stupid. I'm certain someone has the skill to make that end look good.

Awesome! I had not used my macbook for almost a month, since my magsafe quit working. I was afraid to cut into the plug, fearing I might damage the circuitry inside. Once I saw the pictures of the inside of the adapter, I knew the correct way to do it. Thank you for the tutorial. :)

Could you please make the same guide for a L connector?

I repaired my magsafe end and managed to back the white cover off and re-use it. I couldn't re-use the strain relief, but built up a facsimile using hot glue.

How would this be done for the new Magsafe 2 connection? This is aluminum, and not plastic....help would be appreciated!

Having bought a second one of these useless cables, I blue-tacked the connection in place and secured the cable along the side of the computer. Not pretty but at €90 a replacement, well worth it. You can also mould a pretty cover with Sugru.
