The wide connector plugs into the socket labeled KB - that is the keyboard connector.  It appears to be intact -- there's a latch where the edge of the cable slides in.    
Hi All I replaced my battery and I fear that I may have dislodged or broken the cable connector for my keyboard on my Inspiron 7472. The laptop keyboard works with an external keyboard or with the onscreen one but not by itself.  Here is what I see. The black strip with the blue top was glued onto the battery and I had to pull on it - is that what the connectorcable looks like or is it the small white cable in the center there? Thank You  [IMAGE]
