Hey @MarkRendle
My unit has the same / similar issue… here’s what I put in my ticket with Frame.work:
*“I have followed all the steps for my framework laptop 16 DIY edition using your quick start guide. After finishing up the hardware installation and turned it on, after some 15-20 seconds, the keyboard lighted it up and did its the RGB thing 
and then I saw a message saying “input modules not detected” 
. I shut it down, re-seated the touchpad module and restarted it. This time I got a new error message saying " input module connector board not detected”. I have removed the touchpad module, the keyboard, the numpad, the mid plate and I have reseated the memory and the two m.2 drives and then reinstalled the mid plate. I put back the keyboard, with two lavender spacers and then again the touchpad module and the spacers closed everything nicely and powered it up to get the same error message quote input module connector board not detected ". I’m presented with two options, one is to shut down by a long press and that doesn’t work and the second option is to have a short press which takes me to another screen telling me “default boot device missing or failed, insert recovery media and press any key” I put a USB stick with windows11 and pressed the “any” key 
but nothing happens. I also put a USB mouse in and doesn’t work. I’m not sure if it’s relevant but both LEDs on the left and right side next to the first input modules are blinking red and blue. There is nothing on your support website in this regard. Please let me know as this is a brand new laptop and I’m not happy with it not functioning at this point in time after waiting some 3 months. Thank you. *
