Introduction

Parfois, la gaine commence à s'effriter juste à la jonction avec l'adaptateur. Je connais beaucoup trop de gens qui ont jeté leur adaptateur à cause de ça. Avec un peu de temps et de patience, il est possible de le réparer.

  1. Câble arraché
    • Câble arraché

    One option is to cut the protruding plastic. Just be careful not to cut the wires inside as these will be soldered to the cable. If this does not work, then you can proceed to opening the casing. I recommend this if you are hesitant to violate the integrity of your adapter.

    • Regardez la ligne qui va d'un bout à l'autre du chargeur. Il y a un super adhésif qui vise à vous empêcher de démonter le chargeur.

    • Il va falloir couper à travers ce plastique. Coupez tout le long de cette ligne avec un cutter.

    • Ça peut prendre un peu de temps de couper sur les quatre côtés, mais vous saurez quand vous aurez presque tout coupé.

    • Faites attention pour le côté montré dans la dernière image. Il y a quelques composants qui pourraient être coupés...

    Die Öffnung klappt relativ gut mit einer O-Ring Zange, ohne Aufschneiderei. Start bei den aufklappbaren Flügeln.

    What worked reallly well for me was, instead of prying with a screw driver, I took some small pliers and put them right where the little tab flips up, where there’s vertical walls about a half inch apart, and I opened the pliers; do this on both sides a few times and you should be able to open the box without too much damage.

    • À l'aide d'un tournevis plat, commencez à séparer les deux moitiés du chargeur. Il faut forcer un peu pour y arriver.

    • Une fois que vous avez séparé les deux pièces sur les quatre côtés, les deux moitiés restent accrochées. Elles sont collées sur tous les côtés du plastique.

    • Insérez le tournevis dans la partie haute du chargeur et séparez prudemment la feuille aluminium de la coque en plastique. Faites attention à ne pas arracher la feuille d'aluminium des entrailles du chargeur.

    A few note's to make it look like new! And without damaging the outside.

    Tip1. Flip up the bunny ears and use the back of a lighter (or something else plastic that fits) between the gap and twist it open on both sides.

    Tip2. Use a small drill to clean out the rubber cable guide so u can re use it.

    Tip3. Use super glue and clamp the charger long enough for the glue to dry. (don't rush it!)

    • Ici, j'ai déjà enlevé une face de la coque.

    • Utilisez le tournevis pour décoller l'adhésif des deux côtés du connecteur du câble d'alimentation.

    • Insérez le tournevis sur la seconde face de la coque et décollez prudemment le reste de l'adhésif.

    Hi,

    What is the use of the outer wire in the cable ?

    Thanks

    • Mettez bout à bout les deux fils blancs et soudez-les ensemble.

    • Le fil blanc qui vient du chargeur doit IMPÉRATIVEMENT être soudé au câble blanc qui vient du connecteur du Macbook.

    • La gaine thermorétractable permettra plus tard d'isoler le câble. Rétractez-la avec de la chaleur.

    • La dernière photo montre la gaine isolante noire. Vous pouvez la couper à la longueur que vous voulez.

    • Il est capital d'isoler les deux fils. S'ils se touchent, cela crée un court-circuit (autrement dit : BOOOM !)

    Angenommen ich bin so klug und teste das MacSafe einmal nach dem Zusammenlöten ohne die Kabel zu isolieren . Ich sehe ein Lämpchen. Die Freude ist von kurzer Dauer, denn DDDDDRRRRRRRRRTTTTT beide Kabel berühren sich und es kommt zu funken -.-

    ist das Magsafe jetzt hinüber? Gibt es eventuell eine Sicherung? Jemand ähnlich Geniales passiert?

    What if I short-circuited because of non-isolating the cables? Is the magsafe out of order right now?

    LLK - Réponse

    • Procédez à souder le câble noir du chargeur AC au fil extérieur de votre connecteur Macbook.

    • Isolez ce fil. Vous n'avez pas besoin de recouvrir tout le fil, juste assez pour qu'il ne touche ni le fil blanc ni le circuit imprimé de l´adaptateur secteur.

      • Vous pouvez utiliser de la gaine thermorétractable ou du ruban électrique. Si vous utilisez de la gaine thermo, maintenez-la le plus loin possible du fer quand vous soudez, pour éviter de la rétracter avant qu'elle ne recouvre le fil.

    Which solder or soldering Iron you guys used? I am trying to do everything with my Goot 40W soldering iron and nothing happens:-

    1. I tried to join black wire but my 60/40 solder won't stick to it at all.

    2. i tried to replace the whole cable with a new cable bought from Amazon and I am unable to get the joint on PCB to get melted.

    Please help!!!!

    varun_ag - Réponse

    • Recouvrez de scotch électrique le fil blanc et le fil noir que vous venez de souder.

    • Joignez-les avec le ruban isolant pour qu'ils ne fassent plus qu'un seul câble et mettez le chargeur AC dans l'une des deux moitiés de la coque plastique.

    • Si votre scotch est blanc, la réparation se verra moins.

    • Prenez trois attaches rapides et mettez-les autour du câble pour éviter qu'il ne soit arraché de la coque plastique.

    Very useful instruction. I almost bought an expensive replacement. Thanks! I also tied a knot from the wire before soldering. The knot was small enough to fit in the housing where the "round piece" was. The knot will help reduce the chance that the wires being yanked out if you accidentally trip over it.

    hiennguyen - Réponse

    This guide was great, thank you for saving me the costs of a new charger. I found it was possible to use the original plastic attachment between the cable and the ac adapter for the repair.

    I first used a 3mm drill bit and removed the bit of cable in the plastic/rubber piece. I then used a 4mm bit to open the hole further and soften the rubber part of the piece. I then threaded the cable through the piece before soldering in step 10. It makes the fix look more like the charger in the beginning and also prevents the wires being pulled through the opening.

    • Mettez quelques gouttes de colle cyanoacrylate aux bords de la coque. Assemblez les deux moitiés pour refermer le chargeur AC.

    • N'oubliez pas les languettes en plastique qui permettent d'enrouler le câble sur le chargeur... même si ceux-là sont la cause principale de câbles déchirés ! Moi, je ne les mets pas normalement, ou alors je les colle à la coque pour éviter que le câble se casse à nouveau.

    Ajouter un commentaire

    • Mettez quatre attaches rapides autour de la coque, deux dans chaque sens.

    • Certains préfèrent utiliser que de la colle cyanoacrylate pour des raisons esthétiques, mais les attaches rapides solidifient l'ensemble. Si vous préférez faire sans attaches rapides, vous pouvez les retirer après quelques heures, une fois que la colle aura séché complètement.

    Ajouter un commentaire

    • Utilisez un pistolet à colle pour remplir l´écart restant.

    • N'en mettez pas trop, juste assez pour qu´il n´y reste pas d´ouverture de l´extérieur.

    instead of glue, put liquid silicon for bathrooms, that's easier to remove if you need to / however to give a form, when not yet dry, some difficulties ( it sticks on fingers )

    instead of glue i suggest Sugru for the finishing touch.. https://sugru.com/

    sebastianfrith - Réponse

    Instead of using the stub wires I soldered the cable ends directly to the PCB. Although it worked I cannot recommend it as the PCB is easily damaged when removing the pins to which the wires are connected. Pulling off a PCB track would step up the difficulty of repair considerably....

    bommels - Réponse

    Kind of mangled the case when prying it off so I just wrapped it up in duct tape. Ghetto, but works.

    Ola - Réponse

    Also ich halte diesen Reparaturweg für KEINESFALLS fachgerecht. Zunächst lässt sich das Netzteil sehr wohl ganz sauber öffnen und mit Kunststoffkleber (Revell) wieder sauber verkleben. Es schadet natürlich nicht, das Gehäuse zur Sicherheit mit einem Textilband zu verkleben, um 1000% sicher zu sein. Aber doch nicht mit mehreren Kunststoffstrapsen.

    Und bitte nicht mit Heißkleber. Wie viele Tage soll das bitte halten? Bei den Rep.-Kabeln sind doch die Gummitüllen dabei und wenn Ihr nur das alte Kabel abschneidet, könnt Ihr die alte Tülle weiter verwenden.

    Dann lässt sich das Kabel auch sehr gut in die Platine einlöten. Der Zeitaufwand ist dabei unter 30 Minuten. Nein, schwierig ist das keinesfalls. Es gibt bei Youtube auch ein sehr schönes Video dazu. Also keine Angst, ist ganz leicht. Aber ACHTUNG! An Hochspannungsbauteilen haben nur Leute herumzubasteln, die wissen, was sie tun.

Some tips:

* There is a better way to open the enclosure without damaging the edge: using a pliers to push the two sides apart where the bunny ears lift up (google for videos).

* The cable can actually be threaded through the rubber/plastic grommet if you have the patience to remove the broken cable from it and make the two small holes bigger with a drill bit. This can be frustrating but is the only way to keep the original appearance. Be sure to leave enough cable after the grommet for soldering.

* Thin (2-3mm) heat shrink is a good way to insulate the exposed wire after threading it through the grommet.

* If you trust your soldering skills, consider de-soldering the old cables from the terminals.

* Applying a little super glue along the edge and clamping for a few hours is all that is needed to keep it closed permanently.

don - Réponse

Thanks for the tips! If you have pictures of the processes please feel free to modify this guide (especially the opening of the enclosure!) ^__^

* I have seen that in some tutorials and I wanted to to drill a hole through the rubber plastic grommet but didn't have a drill at my office =(

* I did consider de-soldering the old cables but that involved de-soldering other components that are attached to copper plates to get to those terminals. In earlier versions of the AC Adapter this can be done with not so much trouble.

I really appreciate your feedback! Thanks!

Angela Penaherrera -

I didn't try that... We actually ended up just heating it to soften the plastic and that worked, wouldn't advise it though

deavisdude -

Same for me, don: see this as a much easier way to open the case: https://www.youtube.com/watch?v=Yqa9uUKu...

Would be nice if you refer to this solution as alternative, befor starting to cut the case.

Thanks for the manual, I just fixed it!

Lukas -

Is it possible to remove the cord entirely from the circuit board and solder new replacement? I have ordered a replacement and I wonder if its safe to do so? Thank you for your prompt response!

Shawn - Réponse

Yes it is possible. Depending on the model of your charger you might need to de-solder some copper plates on the bottom of the circuit board in order to be able to reach the spots for soldering the replacement cable.

Mine does't work when I put both sides of the casing back on. Works fine with only one side. I tested the soldered contacts - they are fine. I did rip off some of the tin foil by accident thoug. Any clues?

Simon Schneider - Réponse

1.5 hours and very straight forward. I would reiterate the importance of making sure ADAPTER MUST BE UNPLUGGED!! before attempting to remove casing or anything further. I feel like electrical hazards were overlooked in the tutorial.

Joshua - Réponse

Joshua, sorry to say that, but do you really think anybody in his right mind would attempt to remove the adapter casing before unplugging the adapter? Is such a thing even possible? You gotta give people some credit. I doubt such morons even exist. If they do, maybe it's best they don't reproduce. Darwin Awards, you know?

Anyway.

I'm attempting to do the repair as well. Just to say, I had two adapters I wanted to repair, one was a 85W: almost impossible to open. It took ages. I cut it with the knife, all around, then took some pliers to it to force it open, I ended up cracking the case. All that before realizing my soldering iron was toast. I was planning on borrowing one so I didn't give up. I took the other adapter, a 45W, this time, no knife, I went directly with the pliers, it opened directly, no damage. I think there are a lot of different versions of the adapters. Depending on the one you get, you might be lucky.

Both of mine, I need to unsolder to open any further. I'll come back with more news.

nessdufrat -

Thanks Angela - a very useful guide. I used a fine toothed saw to open up the power supply and a drill to scour out the plastic stopper. White duck tape to keep it closed after I glued it back again. Sure beats buying a new one! Time spent - 45 minutes.

cshop - Réponse

Hello, I recently had the same problem and successfully fixed it using this guide so thanks. However, I'm curios, if the adapter does for some reason short circuit, what's the worst that could happen? Will the damage be in my macbook only or is there a risk that I might damage the whole wirings in the office?

DevMan - Réponse

Inspired by this guide. I fixed mine without opening the adapter. I hacksawed the upper part (protruding from the adapter) of the plastic piece connecting the cable to the adapter. Then reconnected the wires as described here (without opening case).

marcellus124 - Réponse

Used the pliers method to open. I unsoldered the remaining cable at the supply and resoldered the cable directly to the power supply board. To protect the cable from future damage, I added a strain relief. I drilled a 2 holes in the side of the case, looped a zip tie through, then strapped the cable to the side of the case. Oriented cable so that it lies along the side of the supply rather than sticking straight out. It is possible to use the plug prongs as a guide to wrap the cable around the case. I did not bother putting the bunny ears back on and closed up the supply with tape.

tkarches - Réponse

The design of the Apple adapters is such that they will all eventually break with how the cable is attached. If you leave some slack in the cable before wrapping the cable around the ears, it will last much longer.

tkarches - Réponse

I think mine must have shorted out before dissassembly. I replaced the charge cable with a new one but the charger must have been damaged when it shorted. Is there like a safety component in the charger that stops charging in the event of a short, and maybe can be replaced??? Can anyone advise??

Eduardo - Réponse

Mine process was just fine, but I have one problem. That thing gets unbearably hot now :( Is it because of extra resistance ?

Dominykas Sribikė - Réponse

Please check that the connecting wires were insulated correctly and that they are not touching anything internally. That might be a hazard. If it heats up so much I would not use it.

Angela Penaherrera -

Opening the case was a B!tcH. One thing I wish I knew ahead of time was more about the basics of soldering. I chewed through a lot of wire just to practice to get the connection right before I ran out of slack and solder too close to the adapter. Buying a cheapo soldering iron (60-watt) was a waste of time. Buy (or rent) an 100-watt so that you can heat the connection up BELOW the wire. Then you can bring in solder from above so that it melts into the wire!! Just need an hot enough gun.

Sean Sumwalt - Réponse

I had a frayed cord, with the conducting metal wire completely detached from the rest of the conducting wire (below the insulating material). If that's the case for you, you can peal off the insulating layer from an old iPhone charger, remove the conducting wire and use it to join the two dead ends on the cord of your macbook charger. Apply some electrical tape on top of it and you now have a working charger!

al 4515 - Réponse

there is an easier way to open the case. Get a number 10 spanner and use it to prise off the case below the cable tidy clips. Wedge the outer 'fork' into the near corner of the space below the cable tidy clips and push the spanner away from you. Pop! Off it comes. Takes 2 seconds with very little physical effort. It is similar to the pliers approach but easier to do.

Stephen Ashworth - Réponse

I have come across many chargers now. Some open the way you said, some are a pain to open. I believe it varies with the year they were manufactured because some have way more glue than others and have a different setup of the circuit board. I now use a hot air gun to soften the internal adhesive, will update the guide later.

Thanks for your comment!

Angela Penaherrera -

Fire hazard man. I’d just replace it.

brian2burnett - Réponse

I’ve managed to accidentally sever the white cord from the circuit board. Is it worth trying to solder it back on?

Guy Hide - Réponse

It is, I have repaired chargers by resoldering the wires onto the circuit board. Just make sure that both wires are well isolated from each other.

Angela Penaherrera -

I used epoxy to glue the enclosure back together, and molded Sugru around the cable to close up the gap and provide a flexible but strong sheath for the cable. Looks like it will turn out nicely!

edward - Réponse

I don’t own any soldering equipment but I spliced the wires with electrical tape and it works just fine.

JC Albers - Réponse

That is far easier to just solder the two leads on the outside without opening the plastic box. Usually there is enough length sticking out of the box for that. Just strip both central wires on two ends (3 mm on each end is enough) and solder them together. Don’t forget to put the isolating shrink-wrap on the wire end before. Better yet, put two isolating shrink-tubes - a smaller one to isolate the central wire and a larger one to cover and hold together the whole thing. First, solder the central wire. Then pull the smaller tube over the connection and heat it to isolate (or use electrical tape). After that solder the mesh. and finally pull the larger tube over the connection and heat-shrink it (or use electrical tape). Done.That is not ideal, but it will work and hold if you don’t pull on it too hard. Can be done in 5 mins, no need to open the box.

Igor Litvinyuk - Réponse

I think this is the right way to repair it while keeping an original look: https://youtu.be/NZrEEJYqJ_w?t=1152
