Nook Tablet Sleeping Death
When the Nook Tablet runs low on battery, it will turn off. Duh..
However, what happens when the battery gets too low? It goes into a "sleeping death" mode. I theorize this is caused by a lack of power management when the device is in sleeping condition.
Here is the related portion of my UART log.. Put in simple terms:wires hooked up internally to read what would be "BIOS" on a desktop or laptop.
fullcap0=0x2067 VFSOC=0x08f0 remcap=0x02e5
fullcap0=battery full capacity
VFSOC= Voltage for? System On a Chip- the value required for the device to operate
remcap= remaining capacity
These values are checked before the screen even turns on. So, if the Nook Tablet has a dead battery, the processor will initialize, then turn off before turning on the screen. The device appears to be totally dead.
I verified that a standard USB cable will charge the device even when it's completely off. I do not have a Barnes and Nobel cable currently, so I don't know if this applies.
The solution is to leave the device plugged in for 2 hours
, then attempt to turn it on.
I hope this helps someone who would otherwise return a totally operational device.
