Which portion is loose?

Disassembling is pretty straight forward. Four T4 (I believe) torx screws, and then four small Philips screws that hold the upper half to the lower. The tilt hinge seems to use a spring for resistance, (also with a small catch to hold the top half down when you tilt it back) although I do not know if you can adjust it, I don't have the piece in front of me at the moment.
