On the bottom right corner of the mother board, use the tip of the blue plastic opening tool to gently flip-up the grey locking flap of the bottom two ribbon cables.

Make sure to only lift the flap and not the connector socket because the socket easily breaks off.

Grab each ribbon cable cable and gently pull away from the socket.

To reinstall, insert the ribbon cable into the connector and close the flap on the black line.

Uncover the hard drive by moving the bottom ribbon cable to the far right.
