OK... now I've been hit by the battery problem. Dual USB iBook, new in late August 02, 700MHz. OS 10.2.5 updated a week or so ago. Noticed it running iTunes 4 day before yesterday with 'visualizer' running. Yesterday I duplicated it as follows: I started with 2 hours 49 minutes battery power after unplugging from wall. Playing a song with visualizer quickly drains the battery. 7 minutes of Pink Floyd with visualizer and its down to about 1 hour 15 minutes of battery left. I stopped the visualizer, which seemed to help a lot, the battery going up to about 1 hour 40 minutes left. I started surfing the web with iTunes playing in the background. I wasn't monitoring the battery any more. About 10 minutes later it suddenly went to sleep due to low battery, no warning... when operating normally a warning appears that you should shut down and that unwarned shutdown will occur shortly. I didn't get that warning. I recall much discussion occuring a month or so ago. What was the bottom lines found in that discussion? Paul
