摘要： An overvoltage protection system includes a voltage divider, a compare circuit, and a switch discharge circuit. A voltage regulator module is connected to the switch discharge circuit via the voltage divider. The compare circuit is connected to the switch discharge circuit. When the voltage regulator module outputs an overvoltage, the compare circuit turns on the switch discharge circuit to discharge remaining power in motherboard components and turn off the computer. The overvoltage protection circuit gives a rapid response to overvoltage output from the voltage regulator module, thereby protecting the motherboard components from being damaged.

摘要： A memory detecting circuit includes five switch elements and two indication devices. A first switch element is connected to a standby power, and also connected to memory sockets of a first channel to receive a first memory detecting signal. A second switch element is connected to the first switch element and the standby power. A third switch element is connected to the second switch element and the standby power, and also connected to memory sockets of a second channel to receive a second memory detecting signal. A fourth switch element is connected to the third switch element and the standby power. A fifth switch element is connected to the fourth switch element and the standby power. When there are memories installed into the memory sockets of the first channel and the second channel, the second indication device indicates that the memories run in a dual channel mode.

摘要： A power-on circuit of a computer includes a heat sink, an SIO chip, a connector, a first electric switch, a second electric switch, and a third electric switch. When the heat sink is installed properly, the heat sink is grounded, and the first electric switch is turned off. After a power-on button is pressed down, a power supply on pin of the SIO chip sends a low level signal to turn off the second electric switch, the third electric switch is turned on, a power supply on pin of the connector is at a low level, and the computer is powered on. When the heat sink is installed improperly, the heat sink is not grounded, the first electric switch is turned on, the third electric switch is turned off, the power supply on pin of the connector is at a high level, and the computer cannot be powered on.
