So I turn on my mini yesterday morning after his weekly Saturday night nap, and what do I find but the battery charge icon freshly installed next to the Bluetooth icon!! When I click on it it says in gray "unknown time until full," then the usual visual options (i.e. icon only, time left in minutes, etc.), "power source: power adapter" also in gray, and the option of opening energy saver. Is my mini trying to tell me he wants to get out more, or do I have some sort of problem here? Everything else seems to be working fine. BTW it's a 1.83 Core 2 Duo running 10.4.11 going on about 20 months of unblemished daily perfection. I haven't added any new peripherals or made any major updates in several weeks.
