Last year's Lenovo Chromebook Duet has an AUE date of June 2028. The good news is, Google makes it extremely easy to find out the date for any Chromebook. That's a good long time for a new Chromebook, but things are trickier when buying an older or second-hand model. The Samsung Galaxy Chromebook 2, for example, was released this March and has an AUE of June 2028. However, the date varies from device to device and isn't necessarily determined by when the device was released or by when you bought it. Google has been working on extending these dates and, as of November 2020, it announced new models would have longer lives, which roughly translates to anywhere from seven to eight years or more. Because Google can only guarantee Chrome OS and browser feature support on non-Google hardware for so long, every device currently has a date on which it stops receiving updates - its AUE date.
You may have seen mentions of a Chromebook's expiration date or Auto Update Expiration date.
If you're thinking of passing a gently used Chromebook on to a friend or family member, or if you're considering buying a used or older Chromebook, there's an important date you need to check first.
