Quick Answer: What replaced 40B20135US?
Discontinued: 40B20135US | Replacement: 40BC0135US
Why LENOVO Discontinued the 40B20135US
The Lenovo 40B20135US is classified as fully discontinued and end-of-life by distributor SHI. In practical terms, that means Lenovo has chosen to end sales of 40B20135US, and it should no longer be considered available for new purchase planning. No public Lenovo notice in the research set provides a detailed explanation, and no announced EOL date was found.
For IT buyers, the key point is straightforward: 40B20135US should be treated as an obsolete procurement target. While Lenovo's product page for the ThinkPad Universal USB-C Smart Dock has remained active, the available research does not show an active manufacturer statement overriding the distributor's EOL classification. As a result, procurement teams should plan around the replacement path to 40BC0135US rather than trying to standardize on 40B20135US.
It is also important to be precise about the replacement relationship. The available research does not include a Lenovo document explicitly stating that 40BC0135US is the official manufacturer-declared successor to 40B20135US. However, for buyers searching for a current option after the discontinuation of 40B20135US, the designated replacement in this transition is 40BC0135US.
What's New in the 40BC0135US
Current purchasing path after 40B20135US
The most important operational change is availability. 40B20135US is fully discontinued, while 40BC0135US is the replacement part to evaluate for ongoing deployments and refresh projects. If your purchasing system still lists 40B20135US, it is a good time to update internal catalogs, approved vendor lists, and budgetary quotes to reference 40BC0135US.
Limited published comparison data
Based on the research provided, there is no direct Lenovo-published technical comparison between 40B20135US and 40BC0135US. There is also no manufacturer document in the source set that maps feature changes from 40B20135US to 40BC0135US. That means procurement and engineering teams should avoid assuming port layout, power delivery, compatibility scope, or management features without validating current Lenovo documentation or reseller confirmation for 40BC0135US.
Known feature on 40B20135US
One documented capability for 40B20135US is support for remote firmware updates and dock management through Lenovo Smart Dock Cloud Service. This matters for fleet environments where centralized dock management is part of desktop support operations. The research provided does not confirm whether 40BC0135US includes the same management model, an updated one, or no equivalent feature. If remote dock administration is important in your environment, confirm that requirement before replacing 40B20135US with 40BC0135US at scale.
What IT teams should verify before rollout
Because published differences are limited, treat 40BC0135US as a new validation item rather than a like-for-like assumption. Review supported notebooks, OS images, dock firmware workflows, and any cloud-based management dependencies that were previously relevant to 40B20135US. This is especially important for standardized workstation deployments, hot-desk environments, and enterprise imaging processes.

Upgrade Checklist
- Remove 40B20135US from active sourcing plans. Since 40B20135US is fully discontinued, update procurement records so buyers do not submit new requests for an unavailable part.
- Substitute 40BC0135US in quotes and catalog systems. Replace references to 40B20135US with 40BC0135US in ERP, eProcurement, and contract pricing tools.
- Verify technical fit. Because the research does not provide a direct spec comparison between 40B20135US and 40BC0135US, confirm compatibility and feature requirements before broad deployment.
- Check management workflow requirements. If your team used the remote firmware update and Smart Dock Cloud Service capabilities documented for 40B20135US, verify whether 40BC0135US supports the same operational model.
- Test with representative systems. Pilot 40BC0135US with the laptop models, images, and user profiles that previously depended on 40B20135US.
- Update internal documentation. Revise standard build guides, desk setup instructions, and support runbooks to reflect the move from 40B20135US to 40BC0135US.
- Coordinate with your reseller. If your deployment depends on exact feature parity, request current availability and documentation for 40BC0135US before final approval.
Bottom Line
The Lenovo 40B20135US is fully discontinued and should no longer be used for new purchasing. For organizations replacing 40B20135US, 40BC0135US is the replacement part to source, but the available research does not provide a Lenovo-published spec-by-spec comparison, so validation is recommended before rollout.
