Quick Answer
Lenovo has one of the broadest Chromebook lineups on the market — budget “100e/300e/500e” education models, mainstream IdeaPad and Flex models, premium Chromebook Plus/ThinkPad lines, and the tablet-style Duet series — each on its own update timeline. Recent Lenovo Chromebook Plus and Duet models get automatic updates until 2033-2036, while older N-series and first-generation 100e/300e/500e models from the 2018-2020 era have already expired. The table below covers popular current and recent Lenovo models, sourced from Google’s official Auto Update Policy list.

This list focuses on consumer and prosumer models sold in recent years — Lenovo’s older N-series and first-generation 100e/300e/500e education models (2018-2020) generally have much shorter or already-expired update windows. Lenovo reuses names like “100e,” “300e,” and “500e” across several hardware generations (Gen 2, Gen 3, Gen 4) with different dates, so always confirm the full generation.
How to Check Your Exact Model
Rather than matching your device against a printed model name, check it directly: open Settings, click About ChromeOS, then Additional details to see the precise expiration date tied to your specific unit.
Comparing Lenovo to Other Brands
Current Chromebook Plus models from Lenovo land in the same 2032-2036 range as recent Acer and HP Chromebook Plus models, so update longevity isn’t really a brand-vs-brand decision — it comes down to the specific model generation. Check the exact model you’re considering against the full list before buying.
FAQ
Do all “100e” or “300e” models have the same AUE date?
No — Lenovo has released multiple generations under these names (Gen 2, Gen 3, Gen 4) with different AUE dates. Always match the full generation label, not just the model family name.
My Lenovo Chromebook has expired updates — can I still use it safely?
It keeps working, but stops receiving security patches. See our guide on what to do once a Chromebook is past its AUE date, including installing ChromeOS Flex as a supported alternative.
My Lenovo Chromebook is frozen or won’t turn on — is that an AUE issue?
No, AUE only affects software updates. For those symptoms, see our Lenovo Chromebook frozen or unresponsive guide or our Lenovo charging light on but won’t turn on guide instead.
