This guide shows a short step by step process of repairing a broken MagSafe charger at the magnetic end. It won't be pretty, but it will work.

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.

Edit Step 1 MagSafe End  ¶ 

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

Edit Step 2  ¶

Edit Step 2  ¶ 

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

Edit Step 3  ¶

Edit Step 3  ¶ 

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

Edit Step 4  ¶

Edit Step 4  ¶ 

  • 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.

Edit Step 5  ¶

Edit Step 5  ¶ 

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

  • At this point there are still exposed live wires carrying DC voltage. To eliminate risk of shock or shorting, cover the bare wires in electrical tape, heat shrink tubing, or Sugru.

To reassemble your device, follow these instructions in reverse order.

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.

040304,

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. :)
