What happens when a Chromebook reaches its auto update expiration date?

How long Chromebooks get updates

Google's Auto Update policy says ChromeOS devices receive 10 years of updates, counted from the platform release date, not from the day you bought the machine. A platform is the set of components a manufacturer chose for the model, such as processor and Wi-Fi, and Google tests updates with those component makers. This is why a Chromebook bought in a clearance sale can have fewer years left than its price suggests. Google says it publishes the end date on that page after a platform's release so buyers can check before they buy, and it tells you to check the date when making a purchasing decision.

For devices from before 2021, the policy is more nuanced. Google's extended updates page says all ChromeOS devices released in 2021 or later automatically receive extended updates, while for a subset of older devices an administrator has to opt in to get the full 10 years. Those devices are marked with an asterisk next to the date in the policy table.

Find your own expiration date

1. Click the clock in the lower-right corner, then the gear icon for Settings.
2. Choose About ChromeOS in the sidebar.
3. Open Additional details and look for the Auto Update expiration date.

Menu wording changes a little between ChromeOS versions, so if you do not see it, search Settings for "update". You can also look up your model in the policy table, which is grouped by manufacturer, and note the month shown under Automatic updates until.

What happens after that date

Area	After expiry
Everyday use	The Chromebook still starts and runs
ChromeOS updates	Automatic updates stop, so new fixes and features do not arrive
Built-in protection	Google says the Chromebook still does a self-check every time it starts up and if it detects tampering or corruption it typically repairs itself
Managed devices (schools and offices)	Google says policies may stop working as intended and technical support is not provided
Android apps and Play Store	Remain available on devices that do not opt in to extended updates, though developers may stop supporting the older versions

The takeaway is that the startup self-check guards against tampering and corruption, but it does not replace security patches for the browser and system. Over time that gap grows, which matters most if you bank, shop or sign in to important accounts on the machine.

Extended updates

For eligible older devices, an administrator can opt in via the Extended Auto-update policy in the Google Admin console. Google says opting in removes all Android-related data and the Google Play Store from those devices, while not opting in means automatic updates do not continue. That policy is aimed at schools and organizations, so for a home Chromebook the practical question is whether your model is in the automatic group. Check the policy table rather than assuming.

What I would do

• Still has time left: nothing, just keep the date in mind.
• Expired or within a few months: back up files to Google Drive or an external drive, and keep the Chromebook for low-risk tasks such as video, documents or a child's homework, without sensitive logins.
• Needs to stay secure: plan a replacement, and check the expiration date on the replacement before you buy. Our thread on how much RAM a laptop needs helps with what else to check.
• Technically curious: the Chromebooks and Linux category covers other operating systems for old hardware; compatibility varies by model, so search your exact model first.
