I don't think it is necessary to remove the three 0.5mm screws. Note: the right-most orange circle should be placed instead of the red circle above the two larger orange circles - those are the 0.5mm screws which secures a small plate under the plastic cover which is in NOT physically (but electrically via two metal contacts) to the mainboard.
