Hi all! I have an old iBook G4 12" that needs a new power adapter and a new battery. I'd like to know if either of you have purchased what's to be found on ebay? Is it reliable harware (seems so anyway)? Then what reference should I take? Apple only sells 65W adapters now so should I go for a 65W adapter? Or stick to the 45W (as it came out of the box)? As for the battery, I guess I'll just follow whatever fits the desciption... Best regards,
