How do I perform system updates on my Acer Chromebook?
Your Chromebook gets better and better over time, unlike a traditional PC. When you turn it on, it updates itself. All of your apps stay up-to-date, and you get the latest and greatest version of the operating system without having to think about it.
For more information about system updates, see the Update your Chromebook's operating system page on the Google website.
For more information, visit the Chrome OS Help Center.
