ZIF socket is broken. Is there a repair short of motherboard replacement?
If the socket is still attached to the logic board you can “McGyver” something. Try to secure the cable with tape or glue but be ultra careful not to break more or shorten something.
This also happened to me. Before I discovered ifixit.com, instead of pulling the ribbon AWAY from the socket, I pulled the ribbon AND the socket out away from the board. Those solder points are way too small to be resoldered back on. So I just live without the backlit keyboard. That is unless someone here can find a way to reattach it.
This is a 4 pin connector, i believe only two are connected. Can anyone post me a good close up photo or test where those go and i will come up with a fix.
