other things. It is not, however, the fastest way to charge your NOOK. You can charge your NOOK through USB when it is on or sleeping. If your NOOK is off, it will not charge, so it turns on when you plug it in.
If your personal computer sleeps or hibernates, it will probably stop charging your NOOK. To charge your NOOK, adjust the settings on your computer so that it does not sleep or hibernate.
We recommend that you turn your NOOK on before plugging it into USB. If you plug your NOOK into USB when it is off, your personal computer might have trouble recognizing your NOOK while it is starting. Your computer should recognize your NOOK after your NOOK has completed its startup.
The first time you connect your NOOK to a personal computer, your NOOK should be on. The computer will install USB drivers for your NOOK, and display a message that this operation is in progress. It will also display a message when it completes installing drivers. You can ignore these messages. They do not affect charging.

What happens now depends on power state your NOOK is in:
Off: Your NOOK turns on and charges. Do not turn it off again. After it starts, it displays a pop- up message that indicates USB is available.
While your NOOK is starting, your computer might try to recognize your NOOK as a USB device and fail. When this happens, your computer displays a message about an unrecognized USB device. You can ignore and dismiss the message.
