This is not a problem I am having it's my mother. Her Macbook's power cord seems to have a shortage in it. The light flicks on and off.. it's to the point you have to jiggle the cord to find that sweet spot in order for it to work. Would this be considered a "design flaw" of sorts? I've read where people complain about the cord melting where the magnets meet on the actual brick portion. That is not where the problem is, but I did notice some distortion there also (looked like melting). The problem is where the skinny portion connects to the brick. It seems to be loose and causing the entire problem. Could I get it replaced for free? There is no water damage, no scratches or bite marks, no wires exposed, nothing like that at all. Is it covered? I know with my Acer all the cords were covered along with the computer and battery, even the Zune includes the headphones that come with the device as part of the warranty. I know Apple loves money so I just wanted to see if this situation would be covered or not before I drive half way through the city to the store. Would it be a problem if i let her use my MBP power cord to charge her MB?
