Owners of certain models of Lenovo computers have found that their USB ports and Thunderbolt ports may not work as they should. Multiple Lenovo notebook models have been identified as having issues with their USB-C connectors. The faulty ports often begin to malfunction after six or 12 months of use. Users having problems with the ports report issues including HDMI output cutting out, an error message displayed for Thunderbolt ports, and more.

Some affected devices fail to charge via the USB-C port with a USB-C adapter. Lenovo has acknowledged the issues and has offered a long list of impacted devices.
