Hi all, So I got my Kindle a few days ago, and haven't apparently used it enough to have this problem… but apparently i ran its battery down completely and never got a battery low signal. It's a little disconcerting to be reading a book and then to have it stop in the middle with no warning. Is there a setting I need to turn on to make it tell me when the battery is low, or some way to get battery status so I don't get caught out like this again? And how the heck do you know when it's done charging? Shannon
