Dell :: Loose Hinges On M1530

I have had my M1530 for abut half a year. At the very beginning I noticed that the screen is not very stiff, for example I the screen lid can be moved by about 2 cm almost with no effort (with one finger) also the he hinges (the bar inside) moves up few millimeters when closing the lid.

It's noticeable when looking at the hinge, and also I can feel that from the force used to move the screen for first 2 cm. The problem des not seem to increase and for the first time I thought its normal, but some time ago I saw an identical XPS without that problem.
