Oh, well just to verify, and I'm not saying you accused me of this, but just for future reference, I did not in any way suggest the OP try to do anything even remotely fraudulent to obtain a new computer. But I do believe that this is a serious malfunction. I know there are thousands upon thousands of apple notebooks sold, and I've only heard of this happening a couple times. I know that things happen and products malfunction, but when it happens, it needs to be addressed accordingly. Weather apple replaces the cord or the computer completely depends on where the fault lies. I agree with MacDawg, that the OP should just take the computer in and have it looked at. I would go to an apple certified repair shop first just to see what they say, simply because apple may be quick to point the finger at someone other than themselves.
