If your device is not turning on, try these steps:
Plug the Chromebook into the charger
Hold the refresh button (top row, looks like a circle with an arrow) and the power button for 10-15 seconds
Double tap the power button
The Chromebook should come on at this point. One last step to try if it does not come on is to close the Chromebook lid and open it again.
