I have a older Mac Ibook G4 year around (2005) or so. I lost my rechargable AC adapter. The thing is I don't know which to buy. any help on how to obtain a new one like which store i should visit and which adapter to buy? link to website or any information will be helpful thank you. i can't turn it on as batterie is dead so only info i remember is "ibook g4" i'll have to recharge it but i don't have the adapter to or know of another way to recharge your Ibook G4?
