With the bezel removed, there are four screws that keep the main LCD in place. Unlike other models, this hp envy m6-1125dx doesn't use side runners to connect to the hinge... it is merely an LCD with brackets.

All 4 screws are the same size. Do NOT disassemble the hinge screws, as it is not necessary.

The images shown here depict the top right screw and bottom right screw. There are two more on the left side of the screen the similar locations.
