Abstract: A method for controlling power in a battery-powered electronic apparatus is disclosed. The electronic apparatus includes a battery, a detection unit and a power consumption estimation unit. The battery supplies electric power to each device within the electronic apparatus. The detection unit periodically detects total power consumption of the electronic apparatus and device information representing an operating state of each device within the electronic apparatus. The power consumption estimation unit estimates power consumption of the each device based on the detected total power consumption and the detected device information of each device.

Abstract: Systems and methods for power management in an information handling system are disclosed. A method may include determining a power requirement of resources configured to receive power from a plurality of power supply units including one or more online power supply units, one or more redundant power supply units, and one or more standby power supply units. The method may also include determining a power capacity of the one or more online power supply units. The method may additionally include determining if the power capacity of the one or more online power supply units exceeds the power requirement of the resources. The method may further include transitioning at least one of the power supply units based on such determining steps.

Abstract: A booting system, a boot program, and a method therefor are provided. A boot source device and a boot target device are connected to each other via a transfer interface. The transfer interface is an interface where booting is supported by a BIOS of the boot target device. The boot source device transfers a first object corresponding to booting data which allows the boot target device to establish and use a connection including an interface other than the transfer interface, which is not supported by the BIOS, via the transfer interface. After the boot target device is enabled to use the interface other than the transfer interface, the boot source device transfers a second object corresponding to booting data for booting up an OS of the boot target device or the like via the transfer interface and transfer interfaces and to the boot target device to boot the boot target device.

Abstract: A semiconductor device includes a plurality of circuits each independently conducting a predetermined process, and a circuit operation control part controlling operation start timings and operation suspend timings so as to mutually interfere with power voltage fluctuations caused by a state transition between an operation start and an operation suspend for each of the plurality of circuits.

Abstract: A system and method for modeling a power over Ethernet component using a common information model. With the profiling of components based on the common information model, a remote agent can query status/capabilities or configure a power over Ethernet component based on messaging that is consistent with a power over Ethernet common information model schema.

Abstract: Disclosed is a computer implemented method, computer program product, and apparatus for determining a safe lower bound for a commonly powered data processing system. A power management module operates the data processing system using at least one nominal operating parameter during an exploration periodicity, with the at least one nominal operating parameter being clock speed. The power management module determines whether a calibration period is occurring. The power management module calibrates the data processing system up to a measurement interval duration expiration. The power management module may repeat operating the data processing system using the at least one nominal operating parameter.

Abstract: Systems and methods for managing blades in the event of a power supply unit failure are disclosed. A method may include determining whether a reduced power capacity of the non-failed power supply units is sufficient to provide an aggregate minimum power requirement of the resources in response to a failure of a particular power supply unit. The method may also include powering down a low-priority resource and not powering down a second resource having a higher priority than the low-priority resource if the reduced power capacity of the non-failed power supply units is not sufficient to provide the aggregate minimum power requirement of the resources.

Abstract: The invention provides a method, apparatus and system for reducing power consumption involving data storage devices. One embodiment involves a process for storing data in a first memory, and in response to the first memory exceeding a first threshold, migrating the data from the first memory to a second memory. In response to the second memory exceeding a second threshold, the process then involves migrating the data from the second memory to the third memory, wherein the second memory is sized and configured to store data targeted for the third memory to intelligently maintain a portion of the third memory in an inactive state.
