Dell Inspiron - Manufacturing defect but not covering the product under warranty

Due to manufacturing defects, Laptop's hinge is internally damaged just by daily normal use, it's under warranty but they're not covering it. When I agreed for fee based service they're charging money for the whole LCD, as normal student I can't pay the price for the whole LCD. It's same like saying buy a new laptop again. This is not the case with me only but with most of the dell customers. On social media, I've found people complaining about this issue but still they're busy in make huge money out of it. This is their strategy to make laptop's hardware with cheap quality which doesn't have life more than * years.
