My nookColor is locked up, how do I reset it?

Easy. You should start with a soft-reset. You shouldn't  lose your data but it will force the device off.

  1. Press and hold the power button for five seconds, then release the power button.
  2. Press and release the power button again for two seconds to turn on your nookColor.

Now, it's best to have it plugged into a power source. The device might not work correctly if the battery is dead :)
