I know! I was the one who spent days tracking this down and reading the EC firmware code.
I’ll give it a try because I want to see this fixed, but I really feel it’s your responsibility right now to spend time on it. I spent days tracking this down, reading EC firmware code, etc.
Support is ignoring my story and asking questions like “do you see this on other OS” but I clearly stated in the thread that people have reported this on all kinds of operating systems. I gave the same reply last time, but they keep ignoring what I write. Last time they asked me “Does the issue only happen when plugged in or in battery mode?” when even the title of my report already says that this is only when AC is connected. It’s hardly possible to have a meaningful conversation with your colleagues if they don’t read what I write in the ticket.
edit: Interesting to see a similar experience here: [RESPONDED] Fedora 38 - Kernel 6.4 - Lenovo Thunderbolt 3 Dock Black Screen - #16 by Christopher_Bates
I think they should have kept separated. As I wrote in the comment above, the issues are probably a bit related, but still separate.
