I'm using a PB G3 Pismo 500 all original spec but 384MB RAM. Since Tiger, I don't get any prediction of the battery time remaining, even after 45 mins of use! Anyone know of this problem and perhaps a fix!? I know it's not the end of the world, but it's slightly annoying - and makes the dashboard widget (which I'd prefer to use due to menu bar size limit!) un-useable. Help!
