It should be noted, if you need to get to ONLY the two primary DIMM slots. DO NOT DO THIS STEP - STEP 6! They are not necessary! Remove the two screws on the left and right of the top panel and slide it upwards away from you, the panel will come right off, giving you what you see in step 7. If you are adding 4 RAM modules, then yes, do all steps in this guide, as DIMMS 2 and 3 are under the keyboard.
Maybe reorder the steps so that if you only need to get to Dimm 0 and 1, do steps 1, 2, and 7, and add a step for removing the plate by pushing up on it after removing the other two screws. By these instructions, I thought just to get that second panel off, I had to do all steps, I got the keyboard off and everything only to realize, it was taking me into dimm 2 and 3 under the keyboard, which I did not need.
