So to eliminate possible issues I:
- Turned off Wifi
- Removed my 8gb MicroSD card
So I called tech support this morning. First person was clueless. Second person disconnected. Third person (who was helpful) suggested I drain the device 100%. Then let the device charge for 4.5 hours to see if that resets the battery.
That should take 24 hours to try (for the battery to drain all the way). I will report back with the results.
Update: I fixed my Nook. Details can be found in a newer post here.
