Methods, apparatus, systems and articles of manufacture to reduce computing device power consumption are disclosed. Examples determine an idle period based on hardware residency of the computing device, and set a timer to wake up a central processing unit (CPU) from a low power idle state after the idle period, the CPU to exit the low power idle state in response to expiration of the idle period.

Methods and apparatus to reduce computing device power consumption

Various embodiments are generally directed to an apparatus, method and other techniques for initiating a transition into a lower power state, determining that a device process prevents a platform processing device from completing the transition to the lower power state and interrupting a processing component from an intermediate power state in order to process the process prior to execution of a defined event.

Techniques for entering a low power state

A next idle state for a processor in a system may be determined based on a previous idle period and a previous idle state. The next idle state for the processor may also be determined based on times when interrupts are generated by devices in the system.

System and method for controlling processor low power states

A method and device for controlling power consumption in a computer having a storage device including a motor and a storage medium is disclosed. The method comprises supplying a first power level to the motor of the storage device to spin the storage medium at a first rotational velocity, detecting a first predetermined condition and responsive to the detection of the first predetermined condition, supplying a second power level to the motor of the storage device to spin the storage medium at a second rotational velocity. A number of user defined preferences and system conditions in the computer may be taken into account in determining the second power level to the storage medium.

Method and apparatus for providing multiple power and performance status for a spinning media

A method for automatically transitioning a processor to another performance level in a demand-based system. One embodiment of the invention provides for the automatic adjustment of processor frequency while preserving system responsiveness. The performance-level policy algorithm detects increased processor utilization quickly enough that transition to a higher performance level is comparable to maximum system performance. The performance-level policy algorithm delays processor transition to a lower performance level so that quick reversals in demand do not precipitate unnecessary transitioning.

Power management system that changes processor level if processor utilization crosses threshold over a period that is different for switching up or down
