Walt: I doubt this behavior had anything to do with the level of the batteries. There would have been one way to find out; remove one for a bit and put it back in. It is not uncommon for batteries to become somewhat unreliable at around 30%, but your description sounds more like a lockup than anything else. (I can't discuss exactly how a battery will performat at a certain level, because they are all different.)

Anyhow, I suddenly got to the point where the Book Port was reading, but absolutely no keystrokes would have any effect. I repeatedly pressed 2, D+F, A+C, etc., but nothing happened--the book just kept right on reading. I started pressing keys randomly at a pretty fast clip and suddenly, the BP just stopped dead and at _that_ point, no keystrokes would work. I emphasize that I had not received a low battery warning and based on the fact that I had been monitoring remaining battery life very closely, I would estimate that there was at least 30%; possibly 35%; of their life remaining when all this happened. I removed the batteries and replaced them with a new set and everything is working fine again, but this struck me as really strange and completely unexpected behavior. -- Walt Smith - Clearwater, FL ka3agm@xxxxxxxxxxxxxxx
