A weakness of the MacBook is it's power cord failure after some times. it become a panicking moment when you cannot charge you MacBook anymore. It brick's it! So at the first sing of little orange or green light not showing when plugged, Just replace it!

In this guide we will change the part of the charger that connect to the computer. you can find this cable on Ebay.

If the broken part is near the transfo, you could easily use the same cord but a bit shorter and you will have to find a way to make a grommet or reuse the old one.

Edit Step 1 5 pins Magsafe connector and cable  ¶ 

  • The Tools:

  • A decent welding pen

  • A wire cutter

  • A lead vacuum pump

  • A big heavy duty spudger

  • A pair of snap-ring pliers installed for external snap-ring. Any long nose would do, this is just perfect for the job if you happen to have a pair :-)

  • Super glue

  • 1 or 2 pair of small clamps

Edit Step 2  ¶

  • Make sure you note the position of the positive and negative.

  • I like to start by removing a bit of lead with the pump

  • Separate the cables, it may require some force, but be careful not to break the board.

Edit Step 7  ¶

  • The replacement cable should come already soldered

  • I like to bend it 90 degrees to help insertion

Edit Step 8  ¶

  • It will be tight!

  • Avoid the flaps areas and the grommet area

Edit Step 12  ¶

  • Keeping the flaps in place put the cover on top.

  • It will be tight, be patient!

  • Make sure the flaps stays in place.

  • You might want to wear gloves, since you are manipulating super glue, you might end up with some on your fingers.

  • Like new

  • The only clue that you made something there is the cleanliness of the cable :-)

Apply and repeat to all your friends victim of faulty cable ;-)

This guide was very helpful in figuring out what needed to be done and how to do it. I don't have access to a lead pump so I ended up removing the old wires and then soldering the new ones on top of the remaining solder. So far it's working just fine!

I wasn't able to open my charger, even when using heat, the pliars as shown here and even a knife. As the damage to my cable was a few inches from the charger I just cut the cord and soldered a new one to the end. Cable looks a bit ratty but you could use white tubing to place over the top.

This guide is great and would definitely use it if possible =)

Thank you guys.. this guide was super helpful, without this I would have to spend 73 box unnecessarily.

Thanks again..

My powersafe adapter(a1436) has broken cable and i want to repair it, do you know how many volts out if you connect the multimeter on the black and white cable? I get 9,77v is that correct?

On the smaller 45W adapters, it is virtually impossible to desolder the white cable because the solder joint is hidden behind a capacitor.

Tip: Pull with some force on the white cable with the pliers, it should come out clean without causing damage. It is not soldered directly onto the board, there is a receptacle in between which you can pull the cable out of. You can use this receptacle to solder or clamp in the new cable, too.

(on the 45W) Be careful not to pull too hard on the white cable/clamp - I managed to rip a piece out of the PCB. Fortunately, I had another power adapter (with the same cable issue) lying around.

One point that is missing from this guide:

Partially remove the copper shielding to gain access to the white cable.

Do it on the side that does not have the capacitor lead soldered to it.

Simply peel off the adhesive tape, remove the tab out of the slot and peel up the shielding (it will look like a tent) to gain some space to access the 'white' solder spot. Be careful not to put too much strain onto the electrolytic capacitor's lead.

redwoood,

you need to solder those new leads to the board - that part seems to be missing here

Are you talking about the ends of the cable ?

If it is the case, just strip a little bit no longer than 3/16" of an inch ( like 3mm ) you have to make sure it is not too long; you can see at the step 8, there is no room on the other side of the board.

And heat it to apply soldering on it so it looks like the picture, it is easy to insert and it weld solidly.

Good articel.

I just repaired the power adapter for my friend's MacBook and it's now working perfectly. The case cracking method is inspired! Never would have thought of using a pair of needle nose pliers that way. I hate that cliche about "thinking outside the box" but it truly applies in this case. Thanks.

BTW,this articel is also very usefull.
