Methods and apparatuses to wake computer systems from sleep states

Abstract

Embodiments of the invention describe apparatuses, systems and methods to detect, during a host platform sleep state, a peripheral device audio jack plug being coupled to (e.g., inserted into) an audio jack connection socket. A specific sleep state of the host platform may be determined, and a system wake event may be generated so that the host platform wakes from the sleep state in response to the peripheral device being coupled to the audio jack connection socket. Thus, embodiments of the invention incorporated in handheld mobile computing devices such as smartphones and tablet computers with limited input / output (I / O) provide a user with alternative means for waking the device from a sleep state.

Description

RELATED CASES[0001]This application is a continuation of and claims the benefit of U.S. National Phase Application under 35 U.S.C. §371, Ser. No. 13 / 997,600, titled “METHODS AND APPARATUSES TO WAKE COMPUTER SYSTEMS FROM SLEEP STATES”, filed Jun. 24, 2013, which further claims the benefit of International Application No. PCT / US2011 / 062262, filed Nov. 28, 2011, entitled “METHODS AND APPARATUSES TO WAKE COMPUTER SYSTEMS FROM SLEEP STATES”, both of which are incorporated by reference in their entirety.FIELD[0002]Embodiments of the invention generally pertain to computing devices and more particularly to power management solutions utilized by handheld mobile computing devices.BACKGROUND[0003]Various mechanisms exist for reducing power consumption of a platform.

AI Technical Summary

Benefits of technology

The patent describes a method for detecting when a peripheral device is connected to an audio jack of a handheld mobile computing device and waking the device from a sleep state to use the peripheral device. This allows users to have alternative means for waking the device from a sleep state, even if it has limited input / output devices. The invention uses ACPI, a standard for power management, to determine the state of the device and to manage the transition between sleep and active states. The patent also describes an apparatus and system for implementing this method.

Problems solved by technology

As a result, these types of devices typically have limited I / O devices; for example, I / O devices for such mobile computing devices may be limited to a touch screen display interface and a limited about of buttons on the bezel.
