Unlike most notebooks and the likes, Chromebook keeps itself fresh, every time you turn the Chromebook on, which only takes 8 seconds to be ready, updates itself. It does this with Apps, and the Chrome OS.
When there is an update;  this wrench icon  will appear on the browser toolbar. If you see this change it is very simple to apply the update;

Click the wrench icon on the browser toolbar.
Select Update Chrome OS.
In the dialog that appears, click Restart. Your Chromebook will shut down and automatically restart, with the update applied. So you, your Chromebook are ready to go anywhere, as it was designed to be.
