A computing device has an energy storage device system with multiple energy storage devices. Various different criteria are used to determine which one or more of the multiple energy storage devices to charge or discharge at any given time to provide power to the computing device. The criteria can include characteristics of the energy storage devices as well as hardware and/or physical characteristics of the computing device, characteristics of the energy storage devices and/or the computing device that change while the computing device operates, and predicted behavior or usage of the computing device. These criteria are evaluated during operation of the computing device, and the appropriate energy storage device(s) from which to draw power or to charge at any given time based on these criteria are determined.

Dynamic power source selection, charging, and discharging

A computing device has an energy storage device system with multiple energy storage devices.

The criteria can include characteristics of the energy storage devices as well as hardware and/or physical characteristics of the computing device, characteristics of the energy storage devices and/or the computing device that change while the computing device operates, and predicted behavior or usage of the computing device.

Dynamic energy storage device discharging

Hibernating a computing system. The method includes detecting at least one condition which indicates the availability of time to perform hibernation optimization steps on the computing system. The hibernation optimization steps optimize resume time from hibernate. The method further includes detecting a trigger indicating that the computing system is to be put into a hibernate state. As a result of detecting the at least one condition and the trigger, the method further includes performing hibernation steps to hibernate the computing system in a way that optimizes resume time from hibernate of the computing system.

Optimized power transitions based on user or platform conditions

A plurality of power budgets are sent to a corresponding plurality of power consumers by a power management point, wherein a total power budget managed by the power management point includes a sum of the plurality of power budgets and an available power budget not assigned to the plurality of power consumers. An additional power request having a power increase amount is received from a first power consumer of the plurality of power consumers. The additional power request is approved when the power increase amount does not exceed the available power budget. The available power budget is decreased by the power increase amount. An approval of the additional power request is sent to the first power consumer.

Collaborative power sharing between computing devices

A component of a computing device such as a processor is operated based on a clock signal oscillating at a frequency. Power management for the computing device is performed by adjusting the frequency of the clock signal applied to the component when warranted and also by idling the component when the component experiences a period of inactivity longer than an idle detection metric scaled according to the adjusted frequency.

Scaling idle detection metric for power management on computing device

A method of controlling power management is provided. In an embodiment, the user provides feedback that the inactivity period before a display blanks is too short. In response to the user feedback, a behavior tracking mode is entered and the inactivity period is adjusted to a period that is more suitable to the user's needs. In an embodiment, the adjustment may be done through incrementing a counter and changing the inactivity period based on the value of the counter.

Keep awake heuristic

Dynamic power controller apparatus, systems and methods are provided which utilize system and user data to control power to components. The present invention employs dynamically controlled idle timeout values which are based, in part, on the historical use of the component. It can also employ user settings, event occurrences and available resources of a system to dynamically control the power to one of the system's components or a remote component. In an instance of the present invention related to hard disk power control, it is employed in an operating system's kernel where disk idleness is monitored. When the hard disk's idle time meets a dynamically computed power control idle timeout, the disk driver is commanded to power down the device.

Dynamic power control apparatus, systems and methods

A system and method for generating a unique identifier for a computer system is disclosed. A master computer system is prepared for duplication and configured to execute a startup program on the next boot-up sequence. The master computer system is then shut down and duplicated. On the first boot-up of the copy or &ldquo;clone&rdquo; computer system, a new unique identifier is created and used to replace all instances of the old unique identifier that was associated with the master computer system. Finally, a setup wizard component is executed to finish configuring the clone computer system in accordance with the customer's personal information making the system ready for commercial use.
