RE: T1650: UEFI + Secure Boot enabled: Cannot boot anymore

Have you checked the power LED error codes when powering the system on? See page 45 in the manual.

There are 2 onboard DisplayPort and 1 onboard VGA video ports in this system. And you have to remove the add-in video card in order to test any of them because the add-in video card disables the onboard video ports.
