How to Fix a MacBook Magsafe Power Adapter/Supply

wire's getting hot and your adapter should be used to cook some eggs? OK! it's time to fix the power cord and make it immediately 'cos your batteries are out of charge uh?
Just some tape, a flat destroyable surface and a good knife. Yes, a good knife.

using a hand for maintaining the adapter vertical you can use the other hand to safely engrave the glued line between the two half boxes. Be aware that the components inside are very close to the external shield you're cutting. 

Make the same with the other 3 sides..

Watch at the adapter inside and delicately put the main body a little out of the body (it helps you watch at the wires). If needed use the knife to force it. 

in order to have a longest exposed wire remove patiently the first internal part of the wire blocker. It's made of a strong rubber and it has a black and harder kernel in wich the coaxial cable (why Steve, WTFW?) is plunged.

Cut the wires, chopping it over the interrupted point.

the external coaxial cable is very delicate. Be careful to not cut off the single wires that compose the cable. Separate them in a longer and a shorter exposed cables, respectively the external and the internal cables.

I've fixed it with a plastic strip (dead blocked) and twisted the cables together.

Simply wrap the cables with a good and stable tape. Close the box and have fun. You should want to use the tape on the first part of the fixed cable. Probably you should use a little plastic cilinder for fixing it. 

Black is the new white uh?
