I can not connect the cable from the logic board to the hard drive back down secure the cable to the logic board. It is a " new " board I got from Ifixit. I get the cable in place, push the brown connector down, but it will not stay down. I tried to keep it down with Kapton tape but that does not work. Am doing something wrong ? The cable just lies atop the the the board and under the brown connector ? Any tips ??
