There are two ways to update the operating system of your Chromebook (ChromeOS)
1. Manually update: You can manually check & force update your Chromebook to the latest available version of ChromeOS (as set by the district admin) by following these simple guided Google steps:
2. Automatic download/reboot - As you are using it, your DS Chromebook periodically downloads the latest available version of ChromeOS (as set by the district admin). When an update is available, you will see notification(s) in the bottom right of your screen. They will guide you to restart the Chromebook to apply the update.
After restart, you can verify the ChromeOS version you are running by pressing alt V at the main Chromebook login screen. The version will appear in the upper right (along with additional info about the device).
