People, all welcome!
How to output bios to external screen via HDMI in Fujitsu LIFEBOOK U554?
The main display is damaged and does not work.
The Fn + F10 buttons for switching the screen do not help, as I understand it, they only work in the system.
I tried to disable the main display cable so that it works via HDMI by default, but it did not help.
I don't know what else to try.
The system boots via HDMI, but there is no way to get into the BIOS and the boot menu.

See the service manuals for your motherboard/laptop. I had a laptop with a broken screen with Avito (some kind of samsung), its built-in display is turned off by unsoldering one resistor with zero resistance.
