Lenovo — Hinge damage and display damage of a 2 year old laptop (product poor build quality)

My hinge broke down by itself and damaged the display. I take care of my laptop really well. It is just 2.5 years old and I had extended my warranty. But I don't have ADP it seems. Since it is a product defect, how can this come under accidental damage! I am seriously pissed off right now. This was not a low-end laptop and I had spent a lot of money on this. This happened on 18/12/2020 and the laptop was bought in 2018. I want Lenovo to repair my system free of cost since there is no external damage to my laptop and this happened from the inside since it had a really bad hinge quality.
