Barnes & Noble NOOK 1st Edition Quick Start Manual page 6

Charge your NOOK
Important note:
DO NOT turn off your NOOK after you have
connected it to a wall outlet or computer to charge. This will stop
the charging process. When you connect it to the wall outlet, your
NOOK will automatically turn on and then go into sleep mode after
the preset amount of time. The first time you charge your NOOK,
or if your NOOK's battery power is extremely low, then it may take
up to 30 minutes before your NOOK turns on and the yellow
charging indicator lights up. This is normal.
You can also charge your NOOK by connecting it to a USB port
on your computer. Please refer to your User Guide for additional
instructions about this feature.
