摘要:
A method and apparatus for user activity-based dynamic power management and policy creation for mobile platforms are described. In one embodiment, the method includes the monitoring of one or more sensor values of a mobile platform device to gather sensor activity data. Once the sensor activity data is gathered, the user state may be predicted according to the gathered user activity and an updated user state model. In one embodiment, the user state model is updated according to the sensor activity data. In one embodiment, a switch occurs from the present power management policy to a new power management policy if the new user state differs from a present user state by a predetermined amount. In one embodiment, at least one time-out parameter of a selected power management policy may be adjusted to comply with a predicted user state. Other embodiments are described and claimed.

摘要:
A power management system and interface providing a flexible and uniform protocol for controlling power management within a computer system including various software layers and add-in components. Clients (registered system elements) requiring power management notification and control become registered (via an associated software component) with a power management coordinator (PMC). The PMC provides information routing functions and address translations to facilitate communication (including power consumption information) between clients at registered identifiers. A programmable power policy manager allows a user to define a performance/economy setting for the system that is communicated to all registered devices so that dwell and decay times are appropriately set by the device. A programmable event sequencer maintains an event notification sequence and control sequence for power events. A programmable power budgeter maintains and allocates power on a request basis for system elements. A programmable thermal budgeter maintains and allocates energy based on thermal considerations. A BIOS interlace couples for communication between an APM BIOS (if present) to send commands and poll for and receive event notification. Registered extensions may be used to provide alternate functionality for the sequencer, the power policy manager, and the thermal and power budgeters. The PMC provides for communication of power status, events, and other information between registered devices and allows registered software applications to originate power events. Other extensions may register to enhance power management.

In some embodiments a detector detects a host or device coupled via a link. A port negotiates with a port of the detected host or device and determines whether to operate as a host and/or as a device. Other embodiments are described and claimed.

In some embodiments a Universal Serial Bus cable includes a first differential pair to transmit bus signals, and a second differential pair to transmit bus signals in a same direction as the bus signals transmitted by the first differential pair. In this manner, a bandwidth of the Universal Serial Bus cable is doubled in that same direction. Other embodiments are described and claimed.

摘要:
A method, apparatus and system to enable a data processing device to operate while seemingly “off”. According to one embodiment, a data processing device is configured to recognize a new system state, i.e., Visual Off. On such a data processing device, when the power button is pressed, the request to turn off the device is intercepted by a module and the device is transitioned to a Visual Off state. To the user, this transition appears instantaneous. During the transition, audible and visual indicators on the data processing device and on human interactive devices (“HID devices”) coupled to the data processing device may be turned off and/or disabled. While in the Visual Off state, the device may be fully operational, or in an alternate embodiment, the device may be placed in a low power state. When the user presses the power button again to “wake up” the data processing device, the device may transition from Visual Off into an “on” state (“Visual On”), i.e., all audible and visual indicators on the data processing device and HID devices coupled to it may be turned back on and/or enabled.
