I bought a mainboard mystery box and received a chromebook mainboard. I swapped it into my Framework 13 chassis with known good RAM and SD and tried turning it on. It turns on, power button blinks a couple times and the LED is white but the screen turns on and stays black. I had hoped that MrChromebox’s EC flash would maybe be the ticket to get this thing working but after reading through some of the information it doesn’t look like it would be possible to enter developer mode to disable write protection without it first booting to a functioning screen. I’ve tried plugging in an external monitor to all four expansion bay slots with no luck. It does seem to respond to holding the refresh button (F2 it seems) and power button at the same time but when it restarts it’s the same issue. Any helpful information to be able to debug this board would be greatly appreciated!
