I tried to charge my macbook and saw it didn't power it.

I checked the wires and saw this:

Looks like it burnt/overheated or something. This is a late 2011 Macbook Air, do you think it's possible for a free replacement, or do I have to bite the bullet and pay like $60 for a new power supply?

I guess it was also weakened by always being bent around there, so they can argue it was just abuse?

Standard death of a Mac power supply.

If Apple doesn't exchange that for you, don't discard it:

You can repair it if you know how to apply cable end sleeves/ferrules (and have the crimping pliers for that).
Carefully cut off the rubber hose close to the case (without damaging the cable inside), isolate the two stranded cables, put on end sleeves, do the same with the cable (noting which is which), and wire them together with screw terminals. Liberally apply electrical tape so it doesn't come apart (you can wrap around the rabbit ears to provide some stability). Works like new :-)

When did you buy your MBA exactly? If you don't have AppleCare, the standard 1-year Apple warranty is over. But you can file a claim with your credit card if you're still within 2 years of your purchase date. Otherwise, see what Apple says. At worst, you'll have to buy a new charger. At best, they'll swap it out for free.

Same thing happened to me, apple store demanded 50 for a replacement, um no. They didn't have any serial numbers or anything from me yet, so I told them where they could stick their power adapter, got back in the car. Arrived at regents street to smiling apple store employees and a free replacement psu.

You *might* be lucky.

If you really have to buy a new one:

(See the column "Related Products" if you need a different wattage.)

Of course, as with all Chinese power adapters, it might kill you, but so far it hasn't killed me.

If it does, how do we know? ;)

Several friends have used similar replacements, and have woken up to a ruined battery in their 1500 laptop.
