i purchased a new powerbook g4. it arrived today. i ran it long enough to drain the battery, and then plugged in in, and it recharged. upon completion of the recharge, the icon in the taskbar turns to the charged symbol, and for approximatly 5 seconds, it will show "charged" then, it will replace "charged" with calculating. when unplugged, it will change to amount of time left on the battery, but when plugged right back in, it will show the charged symbol, and then replace it with calculating. it has been calculating for 10 minutes now, and it seems to me that something is not right. any help is greatly appreciated.

That can be normal behavior, how long does it last and what are your Energy Saver and Display settings set to in Apple Menu> System Preferances?
