They had a Chinese back door in the firmware. Don’t know if that’s still the case. https://www.techworm.net/2015/08/lenovo-pcs-and-laptops-seem-to-have-a-bios-level-backdoor.html They’ve had several major (intentional) security flaws over the years. https://en.m.wikipedia.org/wiki/Lenovo They had a modified UEFI that allows insecure execution of EXEs. The Lenovo laptops given to US military in Iraq had keyloggers that sent all inputs back to China.

I thought Lenovo was two different brands, one consumer (terrible) and one corporate (decent). Is that no longer true?

Haven’t really used the older models but the x1c line is decent imo. Also t14. Z line is also good but focuses on different crowd.
