Abstract: A fan rotation speed test device connected to a computer includes an information processing chip, an indicating unit, and an interface. The interface is compatible with a memory socket on a mainboard of the computer. The computer transfers control instructions to the information processing chip via the interface. After receiving the control instructions, the information processing chip outputs PWM signals by executing programs therein to modulate the rotation speed of a fan. The information processing chip collects rotation speed signals of the fan, then judges if the rotation speed of the fan is according to a predetermined standard by executing arithmetic programs. The information processing chip outputs test result signals to the indicating unit for display.

Abstract: An indicator light control circuit includes a basic input output system (BIOS) integrated circuit (IC), a microcontroller, a signal control unit, an electronic switch, and an indicator light. The microcontroller includes a general purpose input output (GPIO) pin. When different operating options of the indicator light are set into and by the BIOS IC, the BIOS IC controls the GPIO pin of the microcontroller to output command signals, such as a low voltage signal, a high voltage signal and pulse signals, then the signal control unit generates and outputs signals according to the command signals. Thus, the electronic switch is operated to turn on or turn off or to pulse when controlling the operation of the indicator light(s).
