The laptop's body bends when I open the top cover (see the side view). It looks like the right hinge isn't firmly attached to the laptop's body (top view). Everything on the left looks okay, though.

Is this normal for T410s laptops?
no this is not normal.
i try´d this on 3 different t410s - we do not have this problem - contact lenovo support technician to fix your problem.
maybe someday it will get worser and the thin display breaks.
