Lenovo y50 4k - hinge problem?

Guys,
I have this lenovo y50 4k UHD laptop bought about one and half year ago. It's in best condition so far. I am worried about its hinge. It makes weird sound when I open or close lid. It doesn't open or close smooth.
Am i in trouble? Is my hinge gone? Is there anyone else with similar laptop and similar problem?
