I can't find a video of your specific model, but I found one that has a similar model to yours. I would guess that was the video you found and watched yourself, since it shows screws under the feet.
But you don't have the exact same model, based on how close the screw hole on yours is to the foot I would say that it's way closer to the foot on your model.
Since I can't find anything about your exact model, I can't say this for sure. But I would guess that there isn't any screw below the feet of your laptop, this is solely based on how close the screw is to the middle of the foot.
I would start with removing all visible screws, then gently try to insert the thin blue opening pics between the two sides of the laptop in order to open up the clips still holding the parts together even though the screws are removed.
Since there could be missed screws, just be careful in case you feel any resistance when trying to separate the halves, especially around where the feet are placed.
Hope this was helpful! :D
