Unlike the N1E, you MUST register your N2E over a WiFi connection before you will be able to use it.
Using N2E with a MAC Address:
You can gain access to the MAC address prior to registering by following these steps:
Turn WiFi On and Off:
You do not need to go into your Settings Menu to turn WiFi on and off. Simply tap on the clock whe the black status bar is visible. This will bring up a Quick Settings menu. Currently, the only option is to turn WiFi on or off.
Tap the small icon with the circle made out of two arrows on the upper right part of the library (next to the Search icon).
To create a shelf, press the menu button ("n") and thentap Library. Tap the drop down menu and then tap Shelves and then Add Shelf. Shelves can be sorted by title or most recent. B&N ebooks and sideloaded ebooks can be added to shelves. However, books can only be added to shelves by going through the list that pops up when you create a new shelf or edit an existing shelf. There is currently no way to tap on a book to add it to a shelf.
To archive a book directly from your library, double tap on it. The details page will open giving you the option to archive. To archive a book that you have open, tap on the center of the screen to open the reading menu and then tap More. The details page will open.
Going back a Step Without Starting Over from the Menu:
If you are doing sometihng and the black status bar on top of the screen is visible, simply swipe from right to left in the center of the status bar to go back a screen. This does not work when reading. Doing this when in an ebook will only cause you to go back one page.
Sideloaded covers not showing:
(thanks to Lu10ntDan)
The Nook Color and the Nook 2nd Edition use whatever embedded and tagged cover there is *within* the ePub (read: not any acompanying .jpg or .png file) to produce the book cover thumbnail for the Library view.
If you have image files for your books that do not show, they are probably not embedded into the ebook meta data. To fix this, use Calibre to perform a Convert Books->Bulk Convert from ePub to ePub within Calibre on the ebooks that are not working. This will create new versions of your ebooks rgar are built with embedded and tagged covers.
In order for your ebooks to look the same way after converting as they did before: 1) Set the Minimum Line Height to 110% (from the default of 120%) under the Look and Feel section and 2) check the Preserve Cover Aspect Ratio checkbox under ePub Output. Using 100% for the Minimum Line Height creates ePubs with smaller fonts.
Google Contacts Syncing Issue:
If you add or delete a Google contact after linking them to your N2E and the change doesn't register on your N2E, follow the following steps:
Unlink your contacts, re-link, Manually Sync (Library) to get a new contact to appear in Google.
If your N2E stops responding, the FIRST thing you should try is a soft reset:
Press and hold the power button for 20 seconds, and then release the power button. Press the power button again for 2 seconds to restart your N2E.
