Embodiments relate to a system and method for managing energy consumption of one or more processor cores in a multicore processing device. The method includes establishing a temporal interval that includes a plurality of temporal periods and an interval energy target for one or more processor cores. The method also includes determining for each temporal period a period energy target for the processor cores and determining a processor core throttling state for the processor cores. The method further includes adjusting the respective period energy target and the respective processor core throttling state at the beginning of each successive temporal period. The method also includes converging, subject to the adjusting, as each respective temporal period of the plurality of temporal periods is concluded, a total period energy consumption of the processor cores with the interval energy target.

One aspect disclosed is a method including determining a location from a positioning system receiver, determining, using a hardware processor and the location, that the location is approaching a path of direction of visual direction information, displaying the visual direction information on a display of a wearable device in response to the determining, determining, using the positioning system receiver, whether the turn of the visual direction information has been made, determining, by the hardware processor, a first period of time for display of the content data based on whether the turn of the visual direction information has been made, powering on the display and displaying, using the display, content data for the first period of time, turning off the display and the hardware processor following display of the content data.

A Power over Ethernet (PoE) Powered Device (60) is described herein that includes an auxiliary processor (62) that negotiates a power level with a PoE Power Sourcing Equipment using a first link layer (650), means for holding the PoE Powered Device in a low power state, and a second link layer (50) that allows the main processor to communicate over the Ethernet.

Included are methods and systems for controlling power consumption in a data storage system. In some embodiments, a method includes obtaining empirical power consumption data that indicates power consumption by the data storage system and obtaining empirical application event data that indicates an operational performance of the one or more software applications. The empirical power consumption data with the empirical application event data. The at least one processor frequency of the one or more processors in the data storage system is adjusted based on the correlating of the empirical power consumption data with the empirical application event data.

One embodiment provides a method, including: receiving, at an information handling device in a low power mode, a wake indication; waking, responsive to the receiving, the information handling device from the low power mode; receiving, at the awoken information handling device, context data obtained by at least one other device; and performing an action based on the received context data. Other aspects are described and claimed.

Bandwidth for information transfers between devices is dynamically changed to accommodate transitions between power modes employed in a system. The bandwidth is changed by selectively enabling and disabling individual control links and data links that carry the information. During a highest bandwidth mode for the system, all of the data and control links are enabled to provide maximum information throughout. During one or more lower bandwidth modes for the system, at least one data link and/or at least one control link is disabled to reduce the power consumption of the devices. At least one data link and at least one control link remain enabled during each low bandwidth mode. For these links, the same signaling rate is used for both bandwidth modes to reduce latency that would otherwise be caused by changing signaling rates. Also, calibration information is generated for disabled links so that these links may be quickly brought back into service.

An energy offloading system is in direct electric communication with an energy generating system and dynamically receives energy from the energy generating system. The energy offloading system uses energy for high-load computations. The energy offloading system includes computers performing the high-load computations as well as servers, cooling units, and communication devices. When the energy from the energy generating system is terminated, the energy offloading system may power down these and other devices, or may switch these devices to an alternative power source. The energy offloading system may be portable.
