Locate the Power button on the bottom of the device next to the USB port and earphone jack. It’s the only button on the device. To turn the Kindle Fire on, press and hold the button for about 2 seconds and the screen should light up.
To turn the Kindle Fire off, press and hold the Power button for about 2 seconds until a prompt appears on the screen. You can then tap Shut Down and the device will turn off.
