An alternative method to restart your Chromebook is to hold down the power button for at least three seconds. This should first log you out of your Google account, saving your work, any tabs you have open, and the general status of your machine, before powering down the Chromebook.
This enables you to then restart your Chromebook using the power button as normal.
Instead of the above, you can also hold the power button for a single second. This will bring up the Power menu from which you can:
- Shut down
- Log off
- Lock your Chromebook
- Provide feedback
Either select Shut down from the list by left-clicking, or first select Log off and then Shut down.
