I live in Ukraine and have used my iBook G4 in Armenia and Ukraine. My battery died and the new one is not recharging while plugged in. There are no Mac Stores here and the techs are suspect. Can you suggest home trouble shooting tips to figure out why the new battery will not charge. Internal power supply? Instability of electricity coming out of the wall? This is one of those problems that makes you sick to your stomach.....especially living in a less than ideal tech support market.
