I was in bed last night reading my Nook. I wasn't falling asleep or anything but actively reading when all of a sudden the screen went dark and then right to screen saver, like I had just shut it off! I can't remember if I had to turn it back on or if I just went to the touch screen and got back to where I was reading. Weird. This is the only time this has happened. My battery is at about 50% or more. Is this the dreaded "black screen of death" I have read about or something different?
Also I bought my Nook at a B&N Friday night, 4 days ago. If I am having returnable issues do I take it back to B&N or does it have to be sent in?
