Q505UA: How do I remove the bottom panel.

Purchased and Asus Q505UA 2-in-1 laptop for Xmas and I'd like to swap the 1tb 5400 rpm platter drive for a 1tb Samsung Evo 860. I've removed all 10 screws from the perimeter of the bottom panel, but it doesn't seem to want to separate with even moderate pressure. I've checked under the front and back fee at didn't find any more screws (Q504 had these).

Has anyone here taken this panel off of a Q505UA? If so, do I just need to be more forceful in trying the panel away or is there some other trick or fastener of which I should be aware?
