After you disconnect from the charger (or even before), is the Kindle responsive to key presses (with the switches off)? I ask because no power is required to maintain the screen "on", and this is not what we are used to from powered devices. For example, when an E-Ink device "hangs" the last image stays on the screen. So, something is causing the image to appear - but once it is there it isn't surprising that it stays there.
