Describe the bug

FW16 won't boot if Lenovo TB dock is connected. Nothing happens, only power button light turns on. After a while fan might spin up.
If you hit again the power button it turn off immediately.

Nothing happens means that no screen starts, no backlight, no any messages - no memory test, no logo. Just blank. Does not matter if lid is open or closed. This does not seem to be OS related. (?)

If you unplug the dock it works fine.

Lenovo dock is TB4 Universal Dock. (40B00135EU) It works perfectly fine if you plug it in after the FW logo shows.

Tried this again today with 3.05 BIOS, as bad as ever.

This is extremely annoying, as you cannot reboot the OS without pulling out the dock cable.

Expected behavior

It should not matter if dock is connected or not.

Operating System

OS in Win11 Pro 23H2, if that matters.
