A lateral high-voltage device in which conductive trench plates are inserted across the voltage-withstand region, so that, in the on state, the current density vectors have less convergence. The support frame supports the other components and may be attached to other devices. At an instruction from an external control terminal which has recognized the fault of another computer component controller provided for the another computer unit, the computer component controller concurrently controls the operations of computer components provided for the another computer unit by communicating a control signal through a radio transmission path. The clock generator is coupled to the processing module, and is implemented for generating the clock signals according to the control signal.
