The sleep mode on my daughter's NT was working up until this past weekend... when it was working, you'd hit the power button for about 1-2 secs, and the screen would go blank into sleep mode (not turned off), and you'd have to hit the Nook button to get back to the password prompt. Now, when we hit the power button for 1-2 secs, the screen would go blank, but then the password keypad would pop right back up after about 5 secs and stay on. Sleep mode does not seem to be functional anymore. We've played with the settings (power-save, screen display goes off after 2 mins which is the minimum), with no results. My theories, next steps:?? - I am wondering if this coincidentally happened after I installed the GO LAUNCHER and started to d/l from the Amazon apps store? Could've this changed anything? - I was thinking of looking up how to reset the NT back to factory default... but what happens to a couple of games she d/l and paid for from B&N? - I've read here how B&N is offering tech support in their stores? I'll consider bringing it in this by the weekend if I can't get it fixed. - Could there have been an update patch that needs to be d/l? - Lastly, if we do nothing about this, she just needs to totally power down her NT which is not the end of the world. But, she's barely had it for 2 weeks, so we'd rather have the unit functioning as good as new as it should.
