Lenovo straight up broke the USB-C ports support for external displays (and other things) in the latest BIOS update for my machine -- for both Windows and Linux -- and there's no way to roll back and there's not a peep from them on any kind of attempt to fix or even acknowledgement of a problem. Requires a hardware ("pinhole" not power cycle) reset every time I want to switch between external monitor use and laptop only. My bug report/forum post here: https://forums.lenovo.com/t5/ThinkPad-Z-series-Laptops/External-USB-C-display-stopped-working-1-57-BIOS-Update-Z16-AMD-Gen-1/m-p/5228342 https://forums.lenovo.com/t5/ThinkPad-Z-series-Laptops/Exter... -- other people are effected. Last year they pushed out a BIOS update which caused the fan to run 100% of the time. Then a "fix" which caused it to overheat. And in-between there somewhere something was pushed that caused me to have to reformat the whole thing. Lid-open-to-awake in Linux used to simply not work 75% of the time, required a hard reset. Now it works, but there's a 5-10 second pause before display turns on (Windows or Linux) vs almost instant on the work issued laptops I've had recently (MBP M1 and some HP Z series thing, running Linux) Waste of cash. Bought this thing to be my dev workstation when I took a contract job last summer, wish I'd never done that. Software quality / support at Lenovo is a real problem.
