FW16 not booting after mainboard replacement

Hey, I just finished setting up all the internals on a DIY Framework 16 (and getting a replacement mainboard after a screw broke off, which is its own thing…) and I haven’t been able to get the computer to turn on. Pressing the power button doesn’t seem to do anything - screen doesn’t turn on, power button light doesn’t turn on, no fan noises or anything of the like.

Full specs:

AMD Ryzen-7 7840 CPU
GPU expansion
2x official DDR5-5600 8 GB sticks (have tried them both installed and with only one installed)

USB C charging port is in expansion port 4 and is showing a white light; I have my Windows 11 download in a USB-A port in expansion port 6.

Can anyone shed some light on what I can do to fix this?

Maybe the power button isn’t connected?
There’s a power button on the mainboard immediately to the left of the wifi module.
Maybe the display isn’t connected?
Is the mains connected or are you trying to boot from battery power? If not, try connecting the cable.
Sorry if this isn’t very helpful. :wink:
