the charge is still low. When your
NOOK does turn on, it will charge most quickly if you do not use
it while it charges. However, you can use it if you keep it plugged in and charging while you do. If
the battery charge is very low, it can take an hour before your
NOOK turns on.

when you plug it in. You can use your
NOOK while it is charging.
