You are amiss in describing the removal of the right side panel which is not even mentioned in the service manual; here’s how you do it: With the computer laying face down on the removable latch cover side, orient the bottom of the computer so it is facing you. Remove the two torx screws on the bottom of the right side panel. Now, spin the computer around to the top is facing you. Get a wooden block and a rubber mallet and place the edge of the block on the very edge of the top right panel. Hit the block gently on the left top edge then on the right top edge. Keep doing this and the right side cover will begin to slide down towards the bottom of the computer. Now lift off the right panel.
