Abstract

A notebook computer stand includes a base and an anti-theft circuit received in the base. A number of supporting pads are positioned on the top surface of the base, to support a notebook computer. The anti-theft circuit includes a pressure sensitive switch, an alarm, a control switch, and a battery. The pressure sensitive switch, the alarm, and the control switch are connected in series. The pressure sensitive switch is positioned on one of the supporting pads. When the notebook computer is placed on the top surface, the pressure sensitive switch is open. The pressure sensitive switch is closed when not under the pressure applied by the weight of the notebook computer, and the battery supplies power to the alarm, the alarm works, when the control switch is closed.

Claims
