Hi All Been getting two local friends to charge my ibook batteries as when I upgraded the HD from 10 to 30 something went and best guess is that its the power supply system Anyone ever swap one over or repair there's themselves? I have a spare part from ebay but yet to do it. Any pointers or links to how to sites would be useful. I discovered just today that its draining the charged batteries when its left in the iBook so need to keep the out of it untill needed. Cheers M
