Uneven And Touchpad On The One Side - I suspect A Warped Shell Casing - DELL VOSTRO 14 3420

I have a wonky touch pad where the left side leans downwards. This isn't the actual image, this is just an illustration.

As you can see, like in the image, this creates a gap along the edge, (on the left side), whilst the right side of the touchpad remains flushed with the palm rest. When operating the thing, when I left click on the touchpad, I would often have to pressure press for a response. When I close the lid and inspect the innards, I find no issue that I can see. I open the lid, and I find dust on my screen.

So, I remove the battery. The battery looks dusty. I clean it. I remove the touchpad. The touch pad is straight, and there doesn't appear to be anything wrong with the bracket which holds the touch pad in place either.

I think the body might be warped.

I've checked the hinges, the screen, the lid, removed the bezel, checked the hinges.... EVE RY THINN G... and still, I cannot find the cause of the wonky touchpad or warped body issue. I do think the body is warped somehow?

I cannot solve this. Any ideas?🙏

This is a DELL VOSTRO 14 3420.
