An automated system for improving the testing of computer devices designed for coupling with docking devices. A plurality of networked computing devices that are individually connected to a compatible docking device through a slave switch. Each slave switch independently connects or disconnects individual computing devices from an attached docking device based on commands obtained from a server. By controlling the electrical connection between the individual computing devices and attached docking devices, the slave switch can simulate the action of docking or undocking one or more selected computers without human intervention. As a result, the present invention provides a system and method that automates the action of docking or undocking a computer. For example, the present invention is suited for use in computer device testing systems wherein a shut down command is sent to a selected computer, after which the selected computer is disconnected from an attached docking device.
