Lenovo's SHAREit software was preloaded on ThinkPad and IdeaPad notebooks. That was one of the hardcoded password issues I mentioned (along with other problems)

The fingerprint scanner issue also impacted thinkpads, thinkstation and thinkcentre devices:

Did they actually issue a recall on those chips? Someone should update the wiki which still says: ...neither nVidia nor Lenovo ever admitted publicly that the chips were defective. The issue was handled as one of quality control with no "official" revisions issued, and no recalls. (https://thinkpads.com/t61/)
Also your link mentions Lenovo did briefly offer repairs in 2010-2011, so I guess I could have taken part, but that was about 2 years after I ejected the company from my world.
