Door bell went off before 8 AM today. Surprised to see a courier - even more surprised to see small package from Apple. Replacement battery for the AI 1.67 Powerbook. Shortest 6-8 weeks I've ever seen. Maybe because I am Applecared? My portable is the Spring 2005 - 1.67 GHz model with a Superdrive and not the last version which was the DL Superdrive model from the Fall of 2005. Which leads to my question... Anybody know if I should follow the latest instructions for calibrating the new battery. Or just the original that is still posted on the web site? http://docs.info.apple.com/article.html?artnum=86284 I think I'll do the most recent calibration technique as this is the most recent style of battery. Suggestions? Rod
