Power Adapter Cord

The metallic braid internal to the Power Adapter appears to have frayed/broken as the insulation has separated from the junction on the magnetic plug.

So I am really having two issues:
1. is this metallic braid for gounding, merely structural support, or both?
2. why has the insulation separated after only 4-5 months of use?

In either case, is this a replaceable item via AppleCare, or must I purchase a new one? I can electrical tape it for now, however, that seems a poor solution for longterm use.

I have just had the same thing happen. The Insultation at the point where the power cord and the magnetic head meet seems to have melted away. The cord still works on and off, but gets really hot.

I think I will take it too the apple store.

My Macbook is only 7 months old. Is this a known issue with the new magnetic plugs- it seems extremely dangerous and should be cause for re-call if enough people have the same problem.

I've also had this problem happen just this morning - mine was smoking before I managed to catch it (just in time it seems!)

Unfortunately i'm out of warranty too - paying for a new adapter seems a little unfair after just over a year of use, has anyone else managed to get a replacement for this problem out of warranty? If you have then it would help me considerably if I could point the Apple people to this thread to help my cause...

hi all, this is my first time on the apple forums and I wish it was for better reason.

I bought my macbook pro on back order xmas 2005 and got it march 2006. In june of 2006 I had to send it away for repair with a myriad of faults least of all the power cord adaptor.

Like all of you, the wire was fraying where it attaches in to the magnetic head. After the repair all seemed well until few months ago when the plastic started to peel back and as of this morning the wires are all visable and if i want to charge my labtop I litterly have to play with the wires to get it to connect.

the repair I got in June(as in the faults) have all returned in the same fashion and when I rang apple (ireland) this morning theu were less than helpful. The first CS person understood the problem and referred me to some other person who could not be more rude even if he tried. He basically told me that because i am out of warrenty by like 9-10 weeks and notwithstanding that fact that the authorised repair faults re appear they would not do anything for me and hung up.

I am one of the battery fault people too and he made no attempt to fix that either.... like you all, there is serious health and safety risk with electricity and bare wires but apple just dont seem to care... has anyone had any successful claims on this?

I've just returned from the Apple store - £59 worse off i'm afraid - out of warranty units wont be replaced, but I can't fault the Genius Bar for their friendliness and sympathy, it's not their fault after all.

I suppose it could be seen as my fault for not buying AppleCare, but I would expect this kind of component to last as long as the computer it is powering.

The safety aspect of this fault is my main concern - my MBP was sitting on a wooden desk, so a fire would have been a different story.

It's interesting to note that my new adapter now has twice the length of strain relief at the MagSafe connector, maybe this is Apple's admission of a problem with early units...

In response to my post....
unfortunately my situation got worse... I phoned the apple care line on Saturday (12/5/07) and spoke to 1 level 1 guy who passed me onto a technician who could not be more rude if he tried and simply told me that they would not be repairing it and hung up on me.... to say I was furious was an understatement.so afteri had cooled down. i rant back and asked for a supervisor and a really helpful guy (whom i explained all the details to, took my information down) and I got a called back from the After sales unit.

After about 10minutes of calm reasoned talk they were offering to refund me the purchase price due to the consistent faults with the unit and these faults remained after repair but a no longer used repair agent. Permission has to be got...fine.

Monday nite: after exam, came home, wrecked plugged in labtop, had to fiddle with the wires to get it to charge, noticed the charger was ice cold and the block head was about to melt.... suddenly smoke and flames from the charging unit... the charger had packed up and was passing 100% on current. for luck i was there to stop fire spreading.
with 24mins battery i took a picture of burning, emailed it and barely had time to take off essential files which i needed and labtop died. got an email wednesday (16/5/07) that in light of the immense problems I had experienced a full refund of 2004.97euro was processed onto my credit card (with no demands to buy a new mac) which I had said i would and have done. ordered on wednesday and shipped at 4pm

They told me that they had no knowledge that people were having problems with the chargers or with the wires fraying... my mac was 2months out of warrenty and I got a refund in full due to the problems. while my situation was more hightened, you should ring and ask for a supervisor call back and ask for a replacement charger. My entire unit is being collected by TNT today and hopefully have new on tomorow so, let them know of the problems. the shops are not reporting the issues and they never check this forum board becasue when i mentioned it, the senior supervisor didnt know people used it [the forum boards] so ring them... probably the cork number but if it savesu having to buy a new unit when there appears to be a consistent fault, they will have to look at a unit recall or exchange

the cost of doing so is far diminished by the risk of destroying a house if the units are faulty.... best prolific example is the sony incident 280million dollars and not resolved.......

dont give up hope

A hint on removing the MagSafe connector is to tilt the connector with your finger to release the magnetic connection before pulling it away. And always disconnect it by holding the connecter itself rather than just pulling on the cable. Not sure if that is part of the issue, but removing it by yanking the cable would damage any cable eventually.

Also if the cable does fray and wires are exposed, stop using it and call Apple. Do not continue to use a damaged adapter [cable] that can short out and/or cause the adapter to overheat etc.
