how to fix hp laptop?

the model is a hp pavilion dm4 notebook pc. the screen is connected by two joints and the right metallic bit connecting the screen to the joint is not stuck properly. which means that when i close the screen and look closely at the opening, i can see a bit of light-----from the glowing hp symbol. the computer is fully operational but it makes me uneasy when i try to close it. i could use super glue and stick the joint to the screen, that should fix it (i've studied the other side). but i am not sure if it would hinder technicians if i ever sent my computer for repair. would sticking it back be recommended?
