The power slider on the Kindle Keyboard actually does 3 things. It's not just only for switching the Kindle to screensaver. These are the 3 functionality of the power slider: Standby This is the normal function whenever you slide the slider and the screensaver appears. Switch off Hold the power slider for 7 seconds. Restart / Reset (The same function of "restart" found in the settings menu) Hold the power slider for 15 seconds. Update: 12 December 2011: Change "Kindle 3" to "Kindle Keyboard".
