Yeah, his issue seems different from ours. Basically, if I try to boot from dock with the lid closed it freezes on the POST screen with the 'FN' button turned on. Have to hard reboot with lid up in order for it to boot. Really frustrating!

Does anybody know if there is ANY Lenovo dock that works fully with the T450s?
We have one that still works properly (Product Number: 40A10090US; S/N M2B07BNE). It's the only one that was not updated with VIA and Synaptics firmware.
We ordered a brand new dock (S/N M2B0EXT5), but it has the same failure. Apparently, new ones already have the fatal firmware installed.
This problem must affect only a few computers. Otherwise, it would have been fixed by now.

did anybody find how to downgrade the dock firmware please? I have the same issue as in first post. Tried to chage Boot display option, but nothing changed. On X240 is everything working fine (on the same dock), but T450s wont start with lid closed. Thank you for your answer.
EDIT: after downgrade to FW v.03 (https://download.lenovo.com/pccbbs/mobiles/fwdphb03.exe) problem solved (dont know, how many other will start)

(dont know, how many other will start)
Just commenting. The problem update (fwdphb06.exe) was apparently to solve the situation here.

The only problem I figured one is flickering of moving part of Youtube video (strip)...but this problem was figured one with 06 version of docking firmware too...
