By using a T8 Torx screwdriver to remove and reinstall the three hex screws on the bottom case as suggested, I ended up stripping the screw heads when tightening them. By pushing hard on a T9 Torx driver I was able to carefully remove the stripped screws. I would recommend using the proper size hex driver instead of the T8 Torx driver for a more positive grip in the screw head.

To add to my above comment: There doesn't seem to be a correct hex size for these 3 screws in either metric or SAE. Actually, the T9 Torx driver works pretty well. I replaced the stripped screws with three brand new ones.
