How do I restart my Chromebook when it is locked up or frozen?
Sometimes Chromebooks will lock up and not respond when trying to shut down or power up. The first thing to try in this instance is to force the Chromebook to shut down by pressing and holding the power button for 20 to 30 seconds. Then close the lid of the Chromebook and leave it closed for 5-10 seconds. This process should ensure the Chromebook is fully shut down. Then you can open the lid and wait 5-10 seconds to see if it will restart. Note: make sure the battery is charged or the device is plugged in. If it is still not responding, send a technical support request and let us know you tried this step.
