Fixing a shacky LCD Screen

Recently, the laptop lcd (Dell 640m) screen had gotten shaky on me. So I decide to fix it.

First of all, turn the laptop belly up and remove the battery. Remove the 2 screw located at the red arrow.

Secondly, turn it back up and use a flat head screwdriver and gently pry the top out. It should come out easily. Then you will see 4 screw anchoring the LCD screen. Using the philips (Cross head ) screwdriver and tighten it. Presto !!! The LCD is firm again.
