So another keyboard works with this machine, and this keyboard works with other machines. I suspect some quirk with the keyboard that interacts with a quirk in the BIOS. If there are options to change things to do with keyboard device emulation / USB legacy support / 8042 emulation / port 60/64 emulation then it might be worth toggling to see if they help. Or look for different BIOS/UEFI versions for the machine. This class of hardware is not exactly known for high quality firmware.
