I have a first generation iceBook (500MHz/64MB stock/Rage128
Mobility), and I never see this behavior ... however, I recently
talked my girlfriend into a new iceBook, and the model she got
(600MHz/128MB stock/Radeon Mobility M6 LY) does. It doesn't seem to
be predictable as best we can tell, and it doesn't happen often. It
seems to happen whether the laptop is plugged into wall power or not.
(Does it irritate anyone else that there seems to be no *good* way to
differentiate iBook versions? I'm sure there's some motherboard
resource version that's unambiguous, but come on...)
If I can provide any information that might be useful, please let me
know. I have both of these laptops sitting in the same room with me
pretty much every day of the world for at least some period of time.
