Do not remove the footpad on the upper left, there are no screws under any of the footpads on this model of Satellite

Once all of the screws are out, slide your tool of choice between top and bottom (plastic razor, credit card or guitar pick)

Start at front of machine, and work your way around to the black hinge side.

The black hinge side looks almost like it is a separate piece which the silver bottom slides under. Nope! It is attached to the rest of the bottom.

Once you have separated the silver areas, lift the front of the bottom slightly, and push backwards horizontally towards the hinge side. The backside black area "cups" the hinge area, you can not lift it straight up like the rest of the bottom.

As you remove the bottom, do not worry about the on/off button. It is attached to the bottom shell, and has no connection to the motherboard.

The 2nd picture is a side view of the on/off button area after the bottom has been removed. There are no connections or cables of any sort between bottom shell and rest of laptop.
