Quick Answer
Every Chromebook has an Auto Update Expiration (AUE) date, after which Google stops sending ChromeOS and security updates. The device keeps working, but it becomes a growing security risk over time. Your main options are continuing to use it cautiously, installing ChromeOS Flex, switching to a Linux distribution, or replacing the device.
Why This Happens
Google commits to a fixed number of years of updates per model when it’s released, tied to the specific hardware inside. Once that window closes, updates stop permanently, regardless of how well the device still runs physically.
Fix Steps
Step 1: Confirm your AUE date
Go to Settings > About ChromeOS > Additional details, and look for “Update schedule,” which shows your specific expiration date. You can also search Google’s official list of Chromebook AUE dates by model.
Step 2: Keep using it cautiously if it’s just past expiration
A device just past its AUE date isn’t immediately unsafe, but avoid entering sensitive information like banking credentials, and prioritize replacing it over the following months.
Step 3: Install ChromeOS Flex
ChromeOS Flex is Google’s free, official operating system for repurposing expired Chromebooks and old PCs. It looks and feels like ChromeOS but runs independently of the manufacturer’s original update schedule. Create a recovery USB with the Flex image using the same Chromebook Recovery Utility process as a standard reinstall.
Step 4: Consider a lightweight Linux distribution
Distributions like Chrome OS Flex alternative Linux builds, or lightweight options like Lubuntu, can extend a device’s useful life further, though they require more technical setup and lose some ChromeOS-specific conveniences like Android app support.
Step 5: Replace the device if it handles sensitive work
For a Chromebook used for banking, work accounts, or anything storing personal data, replacing it after AUE is the safest choice, since security patches are what protect against newly discovered vulnerabilities.
Still Not Fixed?

FAQ
Will my Chromebook stop working entirely at its AUE date?
No. It keeps functioning normally; it just stops receiving new ChromeOS versions and security patches from that point forward.
Is ChromeOS Flex free?
Yes, it’s a free download from Google, designed specifically to give expired Chromebooks and old computers a maintained operating system.
Does installing ChromeOS Flex erase everything?
Yes, it’s a full reinstall similar to a recovery reinstall, so back up any local files first.
