halula3 Level 1 Level 1

My Macbook Pro charger has been acting weird the past few days: not charging, getting really hot, etc. I went to charge my computer today only to find that the coating over the wires was burned and melted!

I charged my computer last night while watching a movie and unplugged it before going to sleep. I did not use the charger today at all so it must have happened last night?

I do not leave it plugged in without my computer attached.

I have a 2010 Macbook Pro 13".

Has this happened to anyone else before? If so, did Apple replace it? Could this have started a fire??

Thanks, feel free to ask any questions if you need more info

MacBook Pro, Mac OS X (10.6.8)

    I have never had this happen before. It looks like the insulation cracked at the strain relief maybe exposing wires or allowing them to short out.  Do you wrap the cables tightly around the adapter when not in use?

    See Mac notebooks: Reducing cable strain on your MagSafe power adapter


    In any event, I would contact Apple and see what they say.

    It's a common problem. In my experience, Apple will replace it if within warranty or AppleCare, but probably won't otherwise ( although it doesn't hurt to ask ). If in the UK, you have additional consumer rights for up to six years.

    Hi ivan54, I never wrap the cord specifically for that reason. I'm actually realllly anal about keeping the wire straight lol.

    andyBall_uk- unfortunately I live in the US so I'm probably going to have to shell out $80 as my warranty has most likely ended.  I'm going to try anyways!

    Do ask, yes. an Apple store in the US replaced my 2007 one, although it was purchased in the UK & never had AppleCare. Some questions about did I look after it & not over-bend the cable, then ok, here's a new one.

    I have the same problem, except it has happened to my chargers two times, I'm now on my third charger. Same thing each time exactly like your picture shows.

    Similarly I never wrap up the cord, I never pull it out of the plug by the chord (I gentle wriggle it out at the plug) I never leave it in charging and I never leave the wall plug in turned on when the charger isn't being used.

    I don't know why it keeps happening, but by taking extreme care of the charger the issue hasn't occurred again. 

    If anyone has any other solutions to this issue, I too would be keen to know

    I have had the same problem and have replaced two chargers. This is a portable device that will in most case be used at least once a day. No doubt on occasion rough handling may cause some strain on the cable but it does seem that it should not require special precautions when wrapping the cable.

    My viewpoint,

    The thicker grommit is stiff where the cable comes out from the charger. Even though the thinner cable itself is flexible at the point where the transition from stiff to thinner / flexible occurs there will be a failure due to the fact that the cable can not bend and all the strain is focused at this point.

    I would think reducing the stiffness of the grommet or increasing the strength of the flexible cable might prevent the same thing happening.

    Some may consider this a design fault . For sure it is an expensive charger. Maybe apple should think about repairing the cable free of charge?

    I guess - welcome to the club Just had mine burned - with smoke and smell. Good - I was working at home and I have an Apple Store nearby. Bad - $89+tx for the charger. Whatever was the actual reason - this must not happen. This thing can burn the house. Needless to mention that this specific charger - I was keeping it always at home and never wrapped the wire around it. Never in my life anything like this happened to any power adapter.
