Chromebooks require very little in the way of maintenance – just make sure you run updates when you need to in order to keep things running smoothly.
The picture below shows you the Chrome Update Available icon you’ll see in the lower right corner of your screen whenever a new update is available. Click on the icon and then on “Restart to update” and your Chromebook will take care of the rest. When your Chromebook restarts, you will be able to continue working where you left off.
