I'm running the same thing and I get battery full messages. But it is rare, usually only after charging overnight. I get other battery wierdness instead. I get lockups occasionally when plugging in the adaptor. Of course I got a lockup today playing AisleRiot so that might not mean much. I have had it show the charging animation for hours after removing the adaptor. Since the meter drops quick once the first bar goes and total life isn't great I probably should hit eBay up for a new battery.
