Update on Jan 23: We updated this article with additional information provided by Lenovo.
Lenovo’s ThinkPads regularly rank at the top of our best business laptops list, but a serious issue with newer models threatens to damage their strong reputation.
ThinkPad laptops from 2017 to 2019 reportedly contain defective USB-C firmware. First reported by Notebookcheck, the problems are widespread enough for Lenovo to post a support page titled “Critical Intel Thunderbolt Software and Firmware Updates.”
Based on that document, the USB-C ports in more than a dozen ThinkPad laptops are experiencing serious issues. The problems aren’t with the USB-C controllers themselves but with a firmware update pushed out in Aug 2019 that causes software corruption.
Lenovo posted a list of symptoms customers could encounter if they own a defective device:
Lenovo ThinkPad USB-C problems
- 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
Which ThinkPad models are affected?
Dozens of ThinkPad models are affected by USB-C failures, including some of our favorite devices. Among those are the ThinkPad X1 Carbon (5th Gen to 7th Gen), X1 Yoga (2nd Gen to 4th Gen), and P-series ThinkPads. It’s worth pointing out that the X1 Extreme and ThinkPad P1 have different firmware and aren’t affected.
