摘要： A central processing unit (CPU) test system includes a CPU socket, a CPU core controller, and a CPU test device. The CPU core controller stores a start voltage message. The CPU test device includes a voltage detection pin, an analog to digital (A/D) converter, and a microcontroller. The voltage detection pin detects a voltage of an electronic device connected to the CPU socket. The A/D converter converts the detected voltage into a digital signal. The microcontroller controls the CPU core controller to output the start voltage to the CPU socket according to the digital signal. The microcontroller stores a predetermined start voltage message. The microcontroller reads the start voltage message after controlling the CPU core controller to output the start voltage, and determines whether the CPU core controller supplies the start voltage to the CPU socket by comparing the read start voltage message with the predetermined start voltage message.

摘要： A protection circuit includes first and second electronic switches. When a CPU socket does not contain a CPU, a signal pin of the CPU socket outputs a high level signal. The first and second electronic switches are turned on. A data transmitting line of a SMBus is connected to a digital integrated chip. The parameters of the digital integrated chip can thus be regulated. When the CPU socket contains the CPU, the signal pin of the CPU socket outputs a low level signal. The first and second electronic switches are turned off. The data transmitting line of the SMBus is disconnected from the digital integrated chip, to prevent damage to the digital integrated chip.

摘要： When there is a memory module mounted in a memory slot, a memory power circuit provides a voltage to the memory slot. First and second power pins of the memory slot are connected. A first electronic switch is turned on. A second electronic switch is turned off. A programmable logic controller (PLC) outputs a first control signal to the memory power circuit to output the voltage to the memory slot. When there is no memory module mounted in the memory slot and the motherboard is powered on, the memory power circuit provides a voltage to the memory slot. The first and second power pins of the memory slot are disconnected. The first electronic switch is turned off. The second electronic switch is turned on. The PLC outputs a second control signal to control the memory power circuit not to output the voltage to the memory slot.

摘要： A power supply circuit for providing a voltage to a memory slot group with one or more memory slots includes a platform controller hub (PCH), a basic input/output system (BIOS), and a control circuit. The PCH detects whether any of the memory slots are occupied, and notifies the BIOS. If there are any memory slots are occupied, the BIOS enables a general purpose input/output (GPIO) terminal of the PCH. The control circuit controls a power supply to provide or not provide power to the memory slot group based on whether the GPIO terminal of the PCH is enabled.
