First, unplug the cable from the bottom motherboard.

It's a "no-fuss" ribble cable connector.

Then slowly pull the bigger cable.

The cable is glued to the metal case.

Be sure to lift the cable for all its length, so the adhesive won't keep it in place and break it in the following steps.

Do not completely remove the cable - it is linked to the display under the metal case.

Remove the grey adhesive.
