How do you shut off the nook? - Tablets & eReaders

Barnes & Noble Nook HD
Will not take a charge

You can first try doing what's called doing a Soft Reset. It's the first and preferred method to try as you don't lose any files or settings. Hold the power button until the Nook turns itself off. In most cases that will be twenty seconds or more. Then turn the power back on by holding the power button down for about two seconds. Hopefully this will allow you to complete a normal boot process. The second and more dramatic way to get a working Nook back is what's called doing a Hard Reset. This process will put your Nook back to "Just Out of the Box" mode. You will lose any files and settings stored internally inside the Nook itself. The good part in all this is it won't touch anything stored externally on your external SD Cards. To do a Hard Reset Turn the NOOK off completely. Hold the Power button and Home (n) buttons. The device will turn on. Continue to hold both buttons until the device shuts off once again (~15-20 seconds). Turn the device on normally. It will prompt for a factory reset. Press the Home button twice to confirm. ------- The important part in the above is to be sure you start the Nook via holding down both the power button and the Home (n) buttons at the very same time and keep them both pressed down until the Nook turns itself off.

Turn off and wipe screen with a damp (not wet) cloth and then wipe with dry cloth!
