I bought a new Nook Glowlight soon after it came out. I’m happy with it for the most part, but it has an annoying habit of going to a blank screen when I put it into sleep mode.
When I wake the Nook from this blank screen, it looks like it displays the book I was reading correctly, but each tap of the screen advances the text, even if I tap on the bottom to try to get to the Settings menu. Eventually the Nook freezes completely.
To fix this problem, I reboot the Nook when the blank screen first comes up. To do that, I hold the power button down for 20-30 seconds, until the blank screen is replaced by the booting up screen. I know it’s rebooting when I see the word “nook” printed in the middle, then “E-ink”, and finally the spiral of dots that means “loading”.
Hope this helps other Nook Glowlight owners!
