Well, I was just sitting here with my Macbook Pro plugged in as usual, and then I saw the green light on the magsafe connector go out. I disconnected it from the MBP and to my surprise, it has turned into a liquid and burnt my hand. The plastic had melted!

I'm on 74% battery life right now and can't plug it in, so I need a quick solution. I can't find a support email anywhere to request help. There's no way i'm paying $80 for something that has malfunctioned this horribly AND burnt my hand. I need a replacement power adapter TOMORROW, and for no cost.

Is my best bet to go to my local Apple store? What would be my best option here?

    Go to an apple store and show them your melted magsafe connector. I am sure they would give you a replacement right away (I cannot imagine how they could ignore something like this).

    One question: Is the connector on the MBP OK? Could the melting of the connector have caused some internal damage to the MBP? Don't mean to scare you or anything, but I am just curious as I have never heard of this happening before. When you go to the apple store, make sure you take your MBP in as well just to test it out with a new connector and make sure everything is OK.

    In the U.S. you can't e-mail support. But you can call them at 1-800-APLCARE. They are available 7 days a week. Yes an Apple Store is a good bet. Some things to note about these adapters:

    1. You can't pull them by the cord. This may cause fraying.
    2. You shouldn't wrap the cable around the brick, as the cable bending at the brick can bend and fray.
    3. Don't let the cable bend more than 10 degrees at any joint
    4. Use the grounded connector (third prong) with a properly grounded outlet when connecting. Any hardware store will sell you a ground tester plug to make sure your outlet is properly connected.
    5. There is a clear plastic wrapping on some of the bricks which is best if removed.
    6. Pack the power brick cable in a zip lock bag to make sure no foreign elements get in the connector while in the bag.

    Look at this article to make sure you aren't putting it on surfaces which might cause the machine to overheat:

    And run the hardware test that came with the machine to see if it detects anything wrong:

    Hi all.
    I am experiencing the same problem. My adapter is melting down at the junction between cord and plastic near the green light. Approximately 2 cm of cord are afected by the melting process. I had to wrap it with some tape to carry on working.

    Has any of you guys been to see a Genius yet? Any success with the replacement under warranty?

    BTW I had this problem immediately after replacing the battery with the Apple MacBookPro Faulty battery replacement plan. I wonder if overheating is caused by the new battery.

    Thanks

    Ciao

    Hi,

    I had the same with my MBP. I got a new one from Apple. They also told me that it was a known problem.

    Hi, "a brody",

    I've got a MacBook Pro. The MagSafe a.c. brick that came with it has two "hooks" that fold out. I assumed that these were to wrap excess powercable around. So I wrap most of the powercable -- the one that plugs into the MagSafe power socket -- around these hooks, before running the MBP off the brick's power. Then I read your point #2, above. Am I doing something forbidden? If so, then why did Apple build the hooks into the brick?

    The MagSafe a.c. brick came with two plugs. One of them has only two prongs. The other one has a grid (or "mains", as it's called in New Zealand) powercord that ends in three prongs, including ground (or "earth"). Your point #4 cautions the reader to only use a grounded connector. Is there anything wrong with using the ungrounded plug that came with the MagSafe brick?

    The hooks are meant to wind up the DC power cable. If you use them, don't wind the cord tightly - you can damage it. If you don't use the grounded cable, you will feel an electrical current through the metal casework. It's annoying, but it's not dangerous.

    Not necessarily. I don't use the grounded cable and I don't feel the tingling sensation you're talking about.

    I don't feel any current running through the aluminum case either. Perhaps I should put my feet into a metal bucket of water connected to a grounded wire?

    I had a similar problem with my Magsafe adapter - the cord near the magnetic tip was damaged, exposing wires underneath. I took the cord to the Apple Store and they pulled a new adapter off the shelf and replaced it, no questions asked. (The new model looks to be better reinforced.)

    i had the same problem too. I saw that it started to fray and i smelled burning electrical components, and i saw that the insulation right behind the little block with the green light melted and exposed the wires underneath. I think that there is inadequate stress relief behind that section of the cord, and that inadequate stress relief makes it incredibly easy to bend the wire a certain way as to cause a short.

    I was able to get my power adapter replaced through apple care, but as a warning, it may take a week or so for apple to send out a replacement...so you either have to go out and buy an extra, or just suffer the week without your mac..which is not something alot of us would be very happy with.

    here's a pic of my melted magsafe

    Not to to seem like a conformist here, but this also happened to me, albeit in a different fashion.

    While I suggest taking it to your local Apple Store ASAP, don't expect a formal recognition of the problem. My local store had told me that they "never seen this before", even though the same thing had happened to my roommate not two weeks earlier. Also, it took them two FULL weeks to replace.

    Just my two cents.

    The spring on one of the pins in my magsafe connector failed causing intermittent connection to my MBP. Apple replaced the power supply and the cable on the replacement is much more flexible than the original. I no longer wrap the cable on the brackets. I believe that the cables on older original power supplies were inferior to more recent models, but time will tell.

    So from what I hear we shouldn't leave the house and leave our MacBooks pluged in? Incidentally, I was a little confused at first when trying to decide which way up the magsafe should go. It seems to work both ways, but dosn't that conflict with negative and positive electrical laws, or whatever.
