A clock control technique allows reducing the power consumption of devices connected to a computer bus. Individual idle devices can be disconnected from the bus clock by a device clock controller and placed in a low-power state without waiting for all devices on the bus to go idle. When individual devices are idle, transactions on the bus are monitored and unclaimed transactions are claimed by the device clock controller, which then forces a retry of the transaction and reconnects the clock to the idle devices. This brings these devices from the low-power state to a full power state, where they are capable of claiming the transaction when it is retried.

A laptop computer and mating docking station where the docking station provides power to the laptop computer over power rails of the Universal Serial Bus (USB) interface. The laptop computer has laptop docking logic that both provides power in accordance with standard USB protocol, and also receiving power across the power rails of the USB interface. Likewise, the docking station has a docking station dock logic that establishes communication with the laptop docking logic across the USB power rails. Once positive communication is established, the dock station provides voltages on the USB power rails sufficient to power the laptop computer as well as charge the laptops battery.

Context or other functional settings are protected during a power up reset sequence in a computer system, without the need to save such context or settings in static memory. A signal, representing a change in the context, is delayed beyond a critical period of indeterminacy resulting from a power up sequence. Reliable signals, set before an application of power, negotiate the delay prior to an assertion of a power up reset signal. The context or settings are preserved by bypassing the reset signal. Unreliable signals, set during an application of power, are held by the delay to allow the reset signal to clear or initialize the context or settings. The reset function operates without prior knowledge, for example as saved in static memory, of the state of the context.

A storage power optimized server system includes a high performance spinning hard drive for storing a first set of data and a power controlled hard drive for storing a second set of data. The high performance spinning hard drive is continuously driven while the power controlled hard drive may have a lower power consumption, slower access time or higher capacity than the high performance spinning hard drive. The first and second set of data may be based on one or more data conditions. The first set of data may include data that has been requested at a rate above a predetermined threshold, or after a predetermined file age date, or after a predetermined last access date. The second set of data may include data that has been requested at a rate below the predetermined request rate threshold, or before a predetermined file age, or before a predetermined last access date.

Embodiments of the present invention are directed at minimizing power consumption of a computer while permitting the execution of meaningful tasks by programs installed on the computer. In accordance with one embodiment, a method that implements power conserving measures based on the amount of capacity that is available from a power source is provided. More specifically, the method includes identifying the current amount of power that is available from a power source. Then a determination is made regarding whether the current amount of power available is associated with a reduced performance state. If the current amount of power is associated with a reduced performance state, the method changes the configuration of the power consuming devices to place the computer in the reduced performance state.

Generally described, embodiments of the present invention are directed at reducing the power consumed by a CPU. In accordance with one embodiment, a method is provided that transitions the CPU into a reduced power state in response to a fetch operation being dispatched to an I/O device. More specifically, the method includes comparing the latency associated with recovering from a reduced power state with the time remaining before a timer expires. Then, a signal is generated that identifies a timer-specific reduced power state. The method aggregates signals received from different timers to identify a reduced power that is appropriate given all of the processing that is scheduled to be performed.

A client hosted virtualization system includes a full volume encryption (FVE) storage device, a processor, and non-volatile memory with BIOS code and virtualization manager code. The virtualization manager initializes the client hosted virtualization system, authenticates a virtual machine image, launches the virtual machine based on the image, receives a transaction from the virtual machine targeted to the FVE storage device, sends the transaction to the FVE storage device, receives a response from the FVE storage device, and sends the first response to the first virtual machine. The client hosted virtualization system is configurable to execute the BIOS or the virtualization manager.
