I just received and installed my the 13th gen motherboard alongside new top cover and hinges. So far it works fine, I can power up the laptop, log into my Ubuntu, everything seems to be working alright.
Except for the keyboard. It only works when it’s not fully attached to the laptop. With a brief experimentation, it seems like the problem lies on the top-left side of the laptop. If I lift the keyboard away from that area, the power button still lights up and I can type on it.
I know this may be hard to imagine, please find a recording here (hopefully it’s clear enough!):
I’d assume it’s some kind of shortcircuiting or something not connected correctly that disable the keyboard while fully attached, here’s my layout:
Wondering if anyone would have an idea what this could be?
