This was our most accurate theory on the issue.Īnother theory was that the issue has something to do with how Lenovo is handling updates for the Thunderbolt 3 firmware. Over the course of a year or so, depending on how much is being written to the chip, the chip may start to go bad and the firmware could corrupt.

This was based on the fact that, for one, the NVM firmware is highlighted specifically in the knowledge base page, and also because each device affected has had their NVM firmware updated. The issue seemed to be Intel's (not Lenovo's) NVM (Non-Volatile Memory) firmware. What was our theory on why this was happening?
