hi, I think my powerbook powercord is damaged, for a while now when I plug in the cord the light doesnt go on and I have to twist and jiggle it a bit for it to start charging, now it doesnt want to charge at all! Over here a replacement will cost about $100 and none of the decent stores will let me even try out one of their units, they want me to book the powerbook and cord in and then they will charge me. Based on this thread I think it might be a common occurance. Im just not keen on paying to find out if it is the connector thats the problem and then pay $100 to fix it. I have done a google search and have found this site that suggests a custom way to fix it, has anyone tried this? How well does it work?
