    • A power supply for a computer system manager, wherein the power supply has its own secondary power source operable when input power to the system manager no longer meets preset threshold values. The power supply functions in one of a discrete number of power modes depending upon the amount of energy available from either the computer input power or the secondary power source. The power supply switches to one of the group of power modes to conserve secondary power when the computer input power is no longer available. The power modes are controlled by a power mode controller which selectively directs power to discrete components of the system manager as a power conservation technique. The power mode controller always energizes the random access memory of the system manager in order to maintain data integrity. Upon detecting insufficient energy within the secondary power source, the power mode controller terminates all power flow from the power supply, including power flow to the random access memory, at which point the entire system has lost all data and configuration settings.
    • 一种用于计算机系统管理器的电源,其中当所述系统管理器的输入电力不再满足预设阈值时,所述电源具有其自身的辅助电源。 根据计算机输入电源或次级电源可用的能量数量,电源以离散数量的功率模式之一工作。 当计算机输入电源不再可用时,电源切换到一组电源模式以节省次级电源。 功率模式由功率模式控制器控制,功率模式控制器选择性地将功率引导到系统管理器的分立组件作为功率节省技术。 电源模式控制器始终为系统管理器的随机存取存储器通电,以保持数据的完整性。 当检测到二次电源中的能量不足时,功率模式控制器终止来自电源的所有功率流,包括到随机存取存储器的功率流,在该点整个系统已经丢失了所有数据和配置设置。
