My iBook's battery has been acting up: it charges but only lasts for about 5 minutes... on a good day. I don't get it. I know I have better Macs than the iBook, but it is my iTunes server, not to mention the boss of my workplace (it is the BIG server for all Macs at work). It is a truly fine laptop. But, without the iBook plugged in for a few seconds, rarely few minutes, it goes dead. Why? If anybody has tips, or possibly an extra battery (this is a snowbook 12" G3, and since I haven't made 100 posts, I can't use Marketplace), please let me know. Thanks to you all!
