Hinge Tightening for Gateway Tablet PCs?

Okay, the screen on my Gateway CX2724 Tablet PC is beginnning to wobble. I suspect that the screens connection to the center rotating hinge is comming loose. I have looked at the gateway design and I believe there are four screws somewhere on the hinge that hold the screen to the hinge. Does anyone know how to access those screws. Please dont give me crap on taking it back to the store because I hear too much of that. Bessides, I dont trust geek squad because they have already ruined my computer twice and I sure as hell dont trust them with my wallet.
