the two front feet attached to the bottom of your computer rotate outward 90 degrees to provide additional stability when the computer is upright.
to access the inside of the computer,you might find it easier to lay the computer on its side.before laying the computer on its side,rotate the feet inward so the weight of the computer does not break them.

when you are finished and have reinstalled the side cover,turn the two front stabilizing feet a quarter turn outward and set the computer carefully back on its feet.
