upper case close badly

The upper section of the case superdrive slot must be deformed by too much pressure applied to the metal when the MBP is moved using only the right hand over the slot. Always use your two hands holding the MBP by the sides when moving the computer. Now to repair the metal deformation use a spunger or a flat non metallic object, insert the flat side in the center of the slot about 1/4 inche deep and gently flip the spunger until the slot original shape is restored.
