Anyone have any Nasihat about my laptop screen?

I've had my laptop for about 2-3 years and it's been working alright,even since my brother managed to drop it on the floor with the screen open -_- I've noticed lately that the screen is slightly wobbly when I type and the right hinge is kinda squeaky :\ Anyone have any ideas/solutions to what I can do? It's really bugging me >_<
