Charging Recommendations
Your NOOK contains a lithium polymer battery. To maximize battery life:
• Partially discharge the battery rather than fully discharging it. For example, charge
your
NOOK when you see the low charge alert, rather than continuing to use it until it turns
itself o.
• Avoid high temperatures if possible for use and storage.
• Charge the battery half way before storing your
NOOK for a week or more.
• Turn your
NOOK o for storage. If you are going to store your NOOK for more than a
week, turn it o.
Hard Reset
A hard reset is a more aggressive way of turning o your NOOK. It is not resetting your
NOOK to factory settings, which is explained in “Resetting to Factory Settings” on page 168.

• If your
NOOK is not charging
• If your
NOOK is on but not responsive
