I just noticed my backlight stays on all the time. I originally had it set for 45 seconds, I went into Tools - Screen/Keyboard and set Backlight Timeout for 10 Seconds - and it still stays lit all the time. When I put it in the Screen Lock position, it still stays lit. xWhen I plug it into the charger, it goes to the alarm clock mode. This is going to be a real battery drainer!
