Hi All I've had a problem with my dual usb ibook after I installed the 30GB HD. Basically it wouldn't take a power feed without turning off. Makes charging impossible. So I bought a replacement part off ebay and was going to fit it myself but was loathing the idea of going back inside there. Its like a metal onion in there with teeny screws. The HD uprgade took a good 4+ hours and was messy in the extreme. Local apple dealer was going to charge me 110£-ish to do it and net searchers weren't much cheaper so I held off and have had the batteries occasionaly charged by friends with the same ibook. I spotted a post on a pr email list I'm on for a local guy and he did it all for £40, and put the new/used keyboard in too. His details are: Andrew Duffy andrew at macsthatwork.com> 01273 648365 or 07984 116155. www.macsthatwork.com And it appears to be all working fine now. I can plug the lead in and it doesn't cut out, it doesn't drain the battery when one is in and its charged a battery fine. We did discover its in the batch of dodgy motherboards so if there is still a problem it maybe deeper than a quick power supply swap. Hope this has been of some use to people.
