I was just looking for this answer myself and couldn't find anything helpful. So I decided to just forge ahead and fix it or break it. I'll call the side without the ribbon cables the hinge side. If you look at the hinge side from the bottom, you'll see where the power indicator plastic is. Look very close, and you'll see the hinge peeking out very small ways. You need to gently pry that hinge with a small flat-blade screwdriver. Once you've moved the hinge far enough, the plastic insert for the power indicator will be dislodged and come out with no effort. Now you can push the hinge the rest of the way out, gently maneuver the ribbon cables into the slot, and remove the top assembly.
