Lenovo fixes faulty ThinkPad Type-C USB ports

[English]Lenovo has delivered several ThinkPad models with a faulty USB Type C connector. It’s silly that failures only occur after 6 to 12 months of typical use. For affected devices with USB Type C connector, Lenov0 has now released a firmware update, which should solve this issue.

On Twitter I saw the corresponding hint from Aryeh Goretsky on the following linked Neowin article. This is how I first became aware of the topic.

A document on the Lenovo support site states that a number of ThinkPad models have been found to have issues with the device’s type-C connector.

  • USB-C port not working
  • Intel Thunderbolt controller not visible in the OS/Device Manager
  • USB-C or Thunderbolt docking stations not visible or having connectivity problems
  • HDMI output not available
  • System battery not charging with a USB-C power adapter connected to the USB-C port
  • Intel Thunderbolt pop-up error message
  • Intel Thunderbolt safe mode error message
  • BIOS Thunderbolt communication error or hang during POST

The problem only occurs after six to 12 months of use and then the USB 3.1 port fails. Issues that can occur include a malfunctioning Type C connector, HDMI output being turned off, error messages displayed for Thunderbolt connectors, and more. The Lenovo page lists the affected models that ship with Windows 10. The Lenovo support page lists the firmware updates required for each system for download.

Note: Article title amended – it was misleading, because I’ve mixed the words in a wrong order (I’m not a native English speaker) – was obviously too tired this night ;-).
