Realigning Screen Lid

Hello: May be a lost cause, thought I'd ask anyway before talking to someone from the Genius Bar. My MacbookPro took a very a very slight tumble rending the screen lid a little out of place. You can tell it's not aligned by a slight glitch when you close the lid, or look at from the back: the black strip is minutely off kilter on the left hand side. While everything works find, I wonder if the lid can be readjusted. I tried to do manually, but nothing budges. Any thoughts would be welcomed.
Thanks
