Hey everyone, did a quick search and learned a few things, but I still have a valid question. I know all about how to calibrate an iBook battery the first time. I got my iBook today and plugged it in and started it up. It showed 40 minutes until full in the menu. Fast forward 39 minutes (about): Now it said "Calculating... until full". The power adapter light was amber. Another 30 minutes past by. Still calculating until full. I figured something was not right. I check the percent and it shows 100%, yet it still says Calculating... until full and the light is still amber. So, I unplugged it, let it drain until it slept, and charged it back up. All while charging it says the correct times (seemed correct) of how long until it was charged. Then, it gets to a few minutes left, changed to "Calculating... until full" and stays like that. This is where I am now. Charged for the second time. I remember seeing 16 minutes left until full and then 6 minutes until it was full, and then back to "Calculating...until full". Light is amber. Been that way for 10 minutes now. What shall I do. Don't want to call Apple and be on the phone forever, because I'm busy. Any ideas? Ok, now I look, light is green, and it says battery is charged. I guess I'm just impatient. Wow. Oh well, all this typing for nothing would be not good so I'll post this anyway to get ideas!
