摘要： A circuit for controlling time sequence of a motherboard to supply power for a motherboard component includes a control circuit, a switch circuit, and a power conversion circuit. The control circuit is configured for receiving a startup signal during turning on the motherboard. The startup signal is configured to turn off the control circuit to delay a first voltage signal received by the first power receiving terminal for a period of time before outputting a new voltage signal. The switch circuit is configured for being turned off under the control of the new voltage signal. The power conversion circuit is configured for converting a second voltage signal into a supply voltage in response to the switch circuit being turned off, to provide the supply voltage to the motherboard component.

摘要： A voltage measurement apparatus includes a power interface, first and second voltage detecting modules, first and second driving modules, and first and second indication modules. The first voltage detecting module compares an output voltage with a first reference voltage, to determine whether the output voltage is greater than the first reference voltage. The second voltage detecting module compares the output voltage with a second reference voltage, to determine whether the output voltage is less than the second reference voltage. The first indication module indicates the output voltage when the output voltage is greater than the upper limit voltage or less than the lower limit voltage. The second indication module indicates the output voltage when the output voltage is less than or equal to the upper limit voltage and greater than or equal to the lower limit voltage.
