disposing a second display portion over a first side of a second housing portion;
rotationally coupling the first and second housing portions to each other;
coupling a keyboard to the second side of the second housing portion;
sensing accelerations associated with the first housing portion, the second housing portion and the keyboard; and
detecting a transition of the keyboard between hidden and exposed positions by comparing the accelerations;
detecting a perpendicular acceleration vector between the keyboard and the first housing portion;
confirming the transition with ambient light sensors disposed in the first housing portion and second housing portion;
separating the first and second housing portions from each other at the hinge; and
flipping the orientation of the second housing portion relative to the first housing portion to expose the keyboard.
