If you later want to reconnect to that hotspot, you must set it up again. To disconnect
or forget a Wi-Fi hotspot, follow these steps:
1. From the status bar, tap the Settings icon.
2. If Wi-Fi is turned off, turn it on.
3. Tap the Wi-Fi hotspot. This displays a pop-up window.
4. Tap Forget to disconnect from the Wi-Fi hotspot.
For more information on configuring the settings on your NOOK (including turning
off the Wi-Fi card), see “Your NOOK’s Settings” in Chapter 2.
Charging and Caring for Your NOOK’s
Battery
Your NOOK uses a high-tech battery called a lithium polymer battery. You can charge
your NOOK’s battery either by plugging your NOOK into your computer’s USB port
or by plugging your NOOK into a wall outlet using the supplied AC adapter.
Plugging your NOOK into a wall outlet charges the NOOK quicker.
TIP: Just like any electronic device, your NOOK is susceptible to power spikes
and other electrical anomalies. If you want to ensure that your NOOK is pro-
tected from electrical problems, plug it into a surge suppressor when charging
the battery.
Unlike older rechargeable batteries, your NOOK’s battery doesn’t suffer from a
charge “memory.” However, you should still follow some basic rules to maximize the
life of your battery:
NOTE: Charge memory means that over time, a battery can store less power
because it thinks it’s full when it’s not. Essentially, most people don’t operate a
battery-powered device until it reaches zero over time. So, as they recharge it
over and over, the battery recalibrates what “zero” is—thus, the battery holds
less charge. This explains the instructions on such devices to occasionally
drain the battery completely.
