I'm on my second power adaptor for my G4 Powerbook and the wire around the plug has gotten quite chaffed. I have to constantly fiddle with the plug to get it to charge. I found a solution by bending the wire and taping it down to the base of the plug with electrical tape...but now the plug seems to really heat up. I can't bring myself to spend another $80 on a lousy power adaptor. Does anyone have another solution?
