you'll see a subtle shadow to the right of the picture.
If it's the picture of the Laptop to which you refer?? then the shadow is so subtle it's almost non existent!!
What I would is make a selection round the laptop,
press control J to create a new layer of the Laptop only, then duplicate that layer, and with the selection still in place on one of the new layers, go to edit - fill and make sure the foreground colour is black - you can feather the selection before filling if you want a blurred edge - this will be the shadow layer.
Place the shadow layer, between the other two layers where you can alter opacity,
you can also use the transform tool to stretch the shadow and you can move it to either side of the laptop so the shadow is where you want it!!
