I just bought a 1GHz titanium, which, although cosmetically challenged, seems to function pretty well. With one exception, of course. It absolutely refuses to run off battery power. I have a working 500MHz VGA and an 867 tibook, so have a couple of batteries to play with. It seems like it can intermittently sense that a battery is there (runs at 667 MHz on just wall power and switches to 1GHz with a battery installed), but it refuses to run for even a millisecond if I pull the plug with a fully charged battery that keeps the 867 going for over 2 hours. Also, running System Info on it the battery portion sometimes reports the battery with all zeroes, other times with the same cycle count, etc, as when the battery is in the other machine. So that part is flaky, but it never pulls any current from the battery to run on. I know I can just start swapping parts with the 867 but seeing as that one is in great condition, thought I'd ask the question before going down that route. Has anyone experienced this kind of behavior before? By the way, I did the PMU/PRAM reset a couple of times, but that had no effect. Any ideas are greatly appreciated.
