When you have connected the AC adapter and the HDMI cable, press the button to turn the power on.
(If the monitor is stored in a cool place, the screen may flicker briefly when you turn the power on.)
Press the button to switch between Chrome OS or Monitor mode.
TIP
If you turn the product on for the first time, it starts with Chrome OS. After that, the product starts with the last mode you used. However, if you reconnected the AC adapter, it starts with Chrome OS.
