built in webcam stopped working, amongst other things.

I need instructions on how to remove the Dell inspiron M5030 cover in order to repair the components of my laptop. I know the items are loose because I can hear them sliding around when I move the laptop.

the webcam is not the only thing that is wrong with it, when I move the laptop around, sometimes it shuts off, and it's not swinging it around like a bat, I could be in the middle of a game, and shift my lap to get in a more comfortable position and it would shut off without warning. and the ethernet port does not function correctly. actuall it doesn't function at all. I need help and badly.this laptop is a major part of my job as a graphics designs artist, and I need it to be functioning properly in order for me to function properly.
