Lenovo IDG Quality Alert
We have released a critical software and firmware update for a number of Lenovo commercial notebooks shipped from 2017 to 2019. These updates are necessary to help minimize the risk of operational issues and help prevent premature hardware failures. While these updates are specific to Intel Thunderbolt Software, the updates are necessary for all systems listed as affected. It is key that users of all impacted systems deploy these updates.
These Intel Thunderbolt Software and Firmware packages are released via Lenovo Vantage and System Update as Critical Updates. This solution is a preventative measure to address a ROM wear-out problem.
This update combination may not resolve all issues with Intel Thunderbolt Software, external displays, and/or docking. Customers who are still experiencing issues after applying this update are advised to open technical cases with Lenovo Support for further assistance. It is important to note that this update combination is the foundation through which all future fixes will be based. Being at this level is a key first step toward resolving potential Intel Thunderbolt Software and docking issues in the future.
