Abstract: An all-in-one computer system comprising: a base panel having a top surface and a bottom surface; and a screen panel coupled to and extending from the base panel, the screen panel comprising a screen. In some embodiments, a speaker system is coupled to the bottom surface of the base panel to provide a stand on which the base panel can be supported at an angle with respect to a resting surface, wherein the speaker system is configured to be adjusted along the bottom surface of the base panel to adjust the angle at which the base panel is supported. In some embodiments, a processing unit is communicatively coupled to the tilt sensor and to the screen, wherein the processing unit is configured to switch the screen between a touch mode and a non-touch mode based on the angle sensed by the tilt sensor.
