Hi, It is unfortunate to hear about the issues you're having with your case and opening the lid to your laptop. I would recommend having the machine serviced.
I can assure you that a far larger portion of Acer laptops do not have this issue. A lot of research, time and developement go into the area around the hinges to minimize issues, but laptops have had these issues for 20+ years. The hinge is a common component that produces a lot of stress. While we do measure ourselves to others, a quick google search replacing Acer for another manufacture is sure to produce the same results.
