Sounds like your center connector isn’t making a good connection. Were I in your position, I’d compare the physical connector to the ones on the sides, and check the wiring going to it. If I couldn’t find a reason for the problem, I’d contact Framework support about it, they’ll have definitive tests to determine what’s going on. But that’s just me.
I have a similar problem where the keyboard only works in the center position but the backlight never works. I’m going to contact support about it.
When the laptop is on, is the keyboard supposed to work as soon as you put it in position? Because mine only works (with above limitations) after putting the trackpad in place.
oh thats interresting. Does that mean the entire surface has to be covered with modules before power is enabled? Because with only the keybaord and the trackpad installed there are still contacts exposed when the side panels are not in place.
