Make (Acer?) and model laptop?
Not sure about the photographs and the orientation.....
My first thought was that the ribbon cable had detached from some end connector that in turn connects to the motherboard.,
The photographed black ribbon cable has a blue label with "MB" printed on the label. MB likely meaning "Motherboard"....
Possible cable match (verify the model numbers).

Are you able to lift up the plate, take a couple of photos of what is there. Then post accordingly.
In any case there should be a port to the end connection to insert into and lock in place.
Look first and see if you can find the port. Motherboard' s PCB may be labeled in some manner regarding the drive's connection port.
However, to be sure: go to the manufacturer's website and look for the applicable laptop User Guide/Manual. Or even a maintenance manual.
Just do not randomly plug the ribbon cable in somewhere.....
