I'm at a serious loss here, not sure where to turn at this point. Searched these forums a few hours to find a bit of help for my problem but no luck. I apologize in advance if this question has already been asked/answered. I just installed the N2A 16g in my NC. All was working well for a few hours..and suddenly...it...stopped. My NC went into sleep mode and when I pressed the power button to turn it back on, it just didn't!! Wouldn't respond or wake up at all. I have removed the N2A SD card to try and get my Nook working again as normal but still no response. It's permanently off. Won't respond to anything at all. I'm stuck with a BLACK SCREEN! I'm so worried my NC is broken for good! Can anyone help me out at all? Any suggestions would be appreciated greatly!
