In the middle of reading last night - my Kindle just froze. I had almost full battery power and was reading a book I bought from Amazon.
I turned the Kindle off. The screen stayed on! I left it for a couple of minutes thinking that the charge would die, but it didn't. I tried pressing and holding buttons, turning things on and off again.
I finally disconnected the battery and just let it sit for another 2-3 minutes, the screen finally faded and looked 'off'.
After I reinserted the battery and turned it on, it took a looong time to turn on. I went back to the book I'd been reading, I had to choose it from the menu, and it opened to where I'd started reading an hour before. Bummer!
I found my place, turned the Kindle off/on again. Everything is working normally with no more problems, yet.
Anyone else have this problem or know what causes it?
