The cord on the 45w power brick for my iBook G4 has frayed and is no longer usable. I am considering removing the jack from the iBook cord and splicing it onto a 45w yo-yo-style cord (originally used with a 1400) that I have. Are there any issues associated with this of which I should be aware? I want to resolve my problem, but do not want to break my computer in the process, of course.
