The system is going down for power off NOW!
And it is showing the "Kindle Tree" screen with message "Please wait a moment while your Kindle starts up." It has been there a long time. The SSH shell is not responding either. The power must really be OFF (except no blank screen like when using a 7-second power button hold).
Tap power button. Now the "pre-boot" spinner is showing. Now the progress bar while the framework is loading. And now the "USB Drive Mode" screen. The USBNet switched back to mass storage during startup, as expected. Unplug USB cable. Light dimmer than with USB cable, then off, then desktop with dim light. A couple more USB in/out events shows that the screen light changes brightness with USB connect/disconnect events.
