Lenovo is dead to me. I have nothing but issues and I'm not alone. We have a fleet of around 3000 X1E, X1C and T480s. The USB port regularly craps out not sending the display signal to the monitor so my co-workers regularly have to restart their Lenovo after they go to standby. This is super disruptive, especially for our developers. In some cases, connecting a display even causes blue screens. (All our monitors are Lenovo Think visions, too...)

I reported this issue to Lenovo and was stuck in the typical service desk loop of hell. Once I escalated the issue with our Lenovo representative the issue got some traction, but there wasn't any real progress for months and the troubleshooting remained nothing but superficial. Not a single expert got in touch with us to get some real and in-depth hardware debugging logs or whatever you need to truly analyse the hardware faults.

Ultimately, my employer decided to stop follow up on that with Lenovo and to just deal with it. We continue to buy these crappy laptops and monitors despite all the issues they cause us and shove the money down Lenovo throats, like any real company would. /s

I managed some 200 ThinkPad branded laptops around 2018-2020 and that era had issues with Thunderbolt firmware. I believe something wrote to it's memory that was meant as WORM storage, breaking things eventually. I went around all the T480's to update the firmware. In my experience the docks were craptacular but the laptops were pretty solid.
