I am trying to get my 12th gen i7-1280p board to boot in standalone mode and struggling. I’ve had it since they were released in the 13” chassis, but I preordered the new AI 370 board and am trying to move the 12th gen board into a 3d printed case. I did this with my 11th gen board without issue and am wanting to do the same with 12th gen.
Running bios 3.08
CPU: i7-1280p
64gb Ram (2x 32gb Corsair)
1TB WD SN850 nVME
Standalone mode enabled in bios.
If I disconnect the battery while still in the chassis, it still boots fine. But if I pull the board from the 13” chassis… which means no more display, and move it to the printed case, I just get a long series of RGB led flashes when I press the power button. It appears to still want the internal display connected best I can tell. Any other steps you need to follow on a 12th gen board to get it to work ? I’ve disconnected the audio board and wifi module to troubleshoot, no effect.
