Abstract: An alternating current/direct current input device includes an appliance input socket and an information and communications technology (ICT) device. The ICT device is powered by the appliance input socket. The appliance input socket includes a ground contact, a positive electrode contact, a negative electrode contact, and a signal switch. A contact depth of the signal switch in the appliance input socket is less than a contact depth of the positive electrode contact or the negative electrode contact in the appliance input socket. The signal switch is configured to generate a control signal when a direct current connector is separated from the appliance input socket. The control signal can be used to enable the ICT device to disconnect the appliance input socket from a conductive electrode of the direct current connector after the ICT device enters a no load state.

Abstract: An example energy efficiency management method includes detecting a type of sensitivity to a performance requirement of a service running in a device, selecting a part of a plurality of running parameters of the device based on the type of sensitivity, where the selected running parameter is a running parameter with low relevance to the type of sensitivity of the service, and then adjusting the selected part of the plurality of running parameters or an associated parameter associated with the selected part of the plurality of running parameters so that a corresponding resource that is in the device and that is occupied by the service is reduced. Power consumption of the device after the adjustment is lower than power consumption of the device before the adjustment.

Abstract: A power consumption management method and a power consumption management device are provided. When a power module of a power supply for a server is faulty, a power consumption management device receives fault information sent by the power supply, and reduces first power consumption, calculated when the power module works normally, of the server by a first value to second power consumption of the server based on the fault information. The first value is not less than a reduced value, calculated when the power module is faulty, of power consumption of the server. In addition, the power consumption management device adjusts the second power consumption of the server based on a power consumption capping value of the server. Therefore, the solution avoids a breakdown of the server, and further improves power utilization after the power module is faulty.
