Hello,

I thought this was a problem until I recently seen other mac users with the same problem. I noticed that from the brick to the plugin for the laptop, that the cord will develop twisted like features. I am not sure what it is or why it is happening. I am worried though that the wires inside are twisting from use and might do something to cause harm to the cord.

I do notice from time to time while I move my laptop around that the wire develops a big noticeable loops. I unplug the laptop, unloop the wires trying to straighten it out and then plug it back in.

Anyone else experience this sort of problem and knows if I should be worried or if there is a solution to this?

Mine has that issue, but I haven't had any problems.

How do you store the power cable? Do you wrap it around the brick? If so, it needs to be unwrapped using the opposite process as you did when you wrapped it, otherwise you'll get loops in the cable.

olePigeon,
I haven't had any problems with this cable yet. But I have had to replace the brick once due to it failing to charge properly. It was replaced under AppleCare. I don't know if it was due to the twists it had.

cgc,
I rarely store my power cord. Mostly I am moving from room to room and just set it into 3 big loops (holding brick, the 3prong end and the magsafe plug).
However when I do pack it up for travel, I do loose rolls (about twice the size of a fist) and don't roll it around the brick.

I always roll mine around the provided flappy handle bits that many people don't realise are there for that purpose. Doesn't seem to happen to me.
I have plenty of more important things to do, if only I could bring myself to do them....

AKA duckbills, as they are referred to internally at Apple (same name given to the flip out power prongs). You should always wind the cord around them, not the brick itself. Then use the little U shaped clip to attach the Magsafe end of the cord to the wrapped cable.

I'm not quite understanding the OP's problem here. Are you saying that you have permanent loops in the cord that don't untwist themselves when you hang the cord freely? I've never heard of or seen such a problem.

ibook_steve,

Think of it as taking rope and twisting it, that is what it looks like. I can see the twists in the wire. I tried to take a picture but its hard to see the twists.

I know what you mean, I've seen it lots. Not aware of any easy fix for it sadly but as long as you follow the above advice to wrap it around the duckbills (Never heard that one before myself), it shouldn't get any worse and should therefore be ok.

With regards to wrapping the cord around the duckbills: just be sure to always wrap the cord the same direction. You definitely don't want to be bending the cord insertion point into the power block in opposite directions every time you pack up the cord. Even with the stress relief on the cord, you're asking for trouble.

As for the cord itself, it's like coiling a 15-foot mike cable: as you coil it, your fingers give the cord a slight twist so that the cord coils properly. To uncoil it, you twist gently in the opposite direction so that the coil will lie flat onstage. (It's more complicated than that, but you get the idea.) Another analogy would be to think about how you coil and uncoil a garden hose.
