My dog thought it would be a good idea to chew my wife's power cord (A1330) right where it plugs into the computer. Anyway, is it possible for me to cut the line back three or four inches and reattach it to the magnetized fitting that plugs into the Mac? I'm reasonably proficient at things like this, but I wanted to see if others have experience in a similar application. I didn't know what the interals look like with regards to how the wires are attached to the fitting, so I figured I'd ask. Thanks.
