I feel rather stupid asking this question :)

My fans need replacing soon, so I started dismantling my Inspiron 8200 to see if the heatsink was full of fluff and that was causing the problem. I followed the instructions at http://support.dell.com/support/edocs/systems/ins8200/en/sm_en/keyboard.htm#1102774 to free the keyboard which was fine... but I can't work out how to disconnect the keyboard cable!

Dell has no instructions so it must be simple. Does the connector pull out of the motherboard (mine didn't want to budge)? Is there a clip to release it?
