Abstract: A method for reducing power consumption of a memory of a computer device is presented. The memory includes at least two channels, each channel includes at least two storage units, a dirty data storage area is set in the memory, and the dirty data storage area includes at least one storage unit in each channel. After the computer device encounters a power failure, a backup power supply is turned on to supply power to the memory, then the storage unit included in the dirty data storage area is kept in a normal operating state, and a storage unit outside the dirty data storage area in the memory is caused to enter a self-refreshing state. Data in the dirty data storage area is then written to a non-volatile storage area of the computer device.

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. According to the application, a breakdown of the server is avoided, and the power utilization after the power module is faulty is further improved.
