Giriş

If your MacBook no longer charges or you don't see the little orange or green charging light when it's plugged in, check the cord for signs of damage.

In this guide we will change the cord connecting the charger to the MacBook.

Alternatively, you can use this guide to repair your existing cable instead of replacing it.

  1. Tools required:

    • Tools required:

    • A decent soldering iron

    • Wire cutters

    • Desoldering pump

    • A big heavy-duty spudger

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

    • Super glue

    • 1 or 2 small clamps

  2. Open the cord winding flaps. Heat the power brick's plastic casing with a hair dryer, and/or run a razor blade along the seam between the two halves of the casing, in order to weaken the adhesive. This will make it easier to pry the case open. Insert your pliers and pry slowly. (Make sure they stay seated in the inside corners, or you may injure yourself or gouge the case.)

    • Insert your pliers and pry slowly. (Make sure they stay seated in the inside corners, or you may injure yourself or gouge the case.)

    • The cord winding flap will fall out.

    • Do the same on the other side.

    • Work slowly!

    • Handle of your needle-nose plier is laid upon the closed bench vise, insert into the casing, then roll the vise slowly.

    • The casing would be cracked and you can continue to next step

  4. Finish it by hand; you'll have to apply some force. At some point, the case will crack open. (The edges are glued all the way around, and the interior metal sheeting may be glued to the case with a foam adhesive as well.)

    • At some point, the case will crack open. (The edges are glued all the way around, and the interior metal sheeting may be glued to the case with a foam adhesive as well.)

    • The corner pieces inside the winding flaps, with their flat metal springs, may come loose as well; note their arrangement with springs pointing toward the cord, for reinstallation later.

  5. Carefully remove the inside from the shell.

    • Carefully remove the inside from the shell.

    • Be careful not to touch any of the capacitor leads, or you may receive an electric shock.

    • If the inside sticks to one half of the shell, it's probably due to (a) glue around the edge of the A/C connector, and/or (b) foam glue between the inside and the flat of the shell.

    • Use a heavy duty spudger or other pry tool to pry the edge of the A/C connector from the shell, and carefully pry between the shell and the inside to break the foam glue.

    • Use only ESD-safe pry tools. Do not use metal pry tools or screwdrivers.

    • You may find the metallic sheeting breaks a little; that's okay, but try to minimize the damage!

  8. Make sure you note the position of the positive and negative terminals. Start by removing a bit of solder with the pump. Separate the cables. It may require some force, so be careful not to break the board.

  9. The replacement cable should be tinned with solder before solder on the board; just put the leads in place and apply heat to install it. Bending the wire tips 90 degrees helps with installation.

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 =)

Try using bench vise with needle-nose plier

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?
