Abstract: A fan delay control circuit includes a fan connector connected to a fan of an electronic device, a power supplying module connected to the fan connector, and a rotational speed controlling module connected to the power supplying module. The power supplying module is connected to a fan power source and a stand-by power source. The power supplying module may continue to supply power to the fan when the electronic device including the fan is powered off. The rotational speed controlling module includes a square wave generation circuit which generates a square wave signal to control a rotational speed of the fan even when the electronic device is powered off.

Abstract: A warning device includes a main body, a touching switch, and a pressure element. The main body includes a first and a second end surfaces opposite to each other, and defines a receiving room penetrating through the first and second end surfaces. The touching switch is received in the receiving room and includes two spaced pins, an operation pole, and a metal sheet. The operation pole protrudes from the first end surface. The metal sheet is positioned on one end of the operation pole and connected between the two pins. The pressure element includes an operation portion and a pressure portion. One end of the operation portion is connected to the pressure portion and another end is positioned on the first end surface. The pressure portion is above the operation pole. The operation portion pushes the operation pole so as to separate the metal sheet from the two spaced pins.

Abstract: A fan delay controlling apparatus includes a connector connected to a fan of an electronic device, a power supplying module connected to the connector, and a power controlling module connected to the power supplying module. The power supplying module is connected to a fan power source and a stand-by power source. The power controlling module controls the power supplying module supply power to the fan when the electronic device including the fan powers off until an ambient temperature is lower than a predetermined value.

Abstract: A computer system includes a cabinet, a motherboard, and a control device. The cabinet includes a front panel. The front panel has an network cable interface. The motherboard is received in the cabinet and electrically connected to the network cable interface. The control device includes a controller and an LED. The LED is positioned on the front panel. The controller is connected to the LED and the network cable interface. The controller turns the LED on if detecting that a network cable is plugged into the network cable interface and turns the LED off if detecting that the network cable is plugged out from the network cable interface.

Abstract: A circuit for indicating operating status of a plurality of hardware devices of a computer includes a detecting module, a decoding module, and an indicating module. The indicating module includes a dual color indicator and two electronic switches connected to a first input and a second input of the dual color indicator respectively. The detecting module detects an operating status of the plurality of hardware devices, and outputs state signals of each hardware device during power on self test of the computer. The decoding module decodes the state signals, and outputs level control signals to turn on or off the two electronic switches. The dual color indicator indicates operating status of the plurality of hardware devices by shifted to be at different indicating states by the two electronic switches correspondingly.

Abstract: A fault analysis result generating system includes an extracting unit, a converting unit, a determining unit, and a result generating unit. The system extracts fault analysis files, converts the fault analysis files to a first predetermined file format which is easy to be processed, converts the fault analysis files with the first predetermined file format to a second predetermined file format, and then transfers the fault analysis files with the second predetermined file format to a learning sharing module.
