I had this happen and it indicates that you have updates waiting to install you would need to go to my account in this site and download the updates which is probably Chrome
It's never done that for any of the other updates though.... And it wouldn't turn on for hours. Eventually I just let the battery run out and tried it again. But it did the same thing.
So I reset it....
Now, I've lost all that I've downloaded with Google, I can't get them to download again. It still says they're installed, even after I removed them on Google Play. Or tried to at least. And some times it turns off on its own. I have no idea what is going on with my Nook....
