Thanks for checking. Further research said to remove battery. Did that, can’t now figure out how the screen saver is showing with no power. Was told that removing battery then replacing it would make it reboot. Talked to NOOK tech and advised to take it to B&N for testing and/or get an upgrade. Figgers.
Screen saver doesn’t need power. It’s one of the main design features of readers, they only use power when changing the screen.
