    Health says 100%, but the 97% charged thing is weird, since it's plugged in. Also, it says it has had 3 charge cycles, but all I did was charge it fully when I first got it (before i even turned it on), and then ran it down once, and back up. Kept it plugged in ever since. I just got it a week ago. Is the 97% thing normal? and why does it say 3 cycles instead of 1, thanks.

    On page 52 of my powerbook user guide " might sometimes notice that the battery does not attain full 100% charge when the power adapter is attached. This is normal behavior; battery life is saved when charging is not continuously cycled on and off when the battery's charge capacity is between 95 and 100%"

    Hope that helps.
