摘要:
A technique includes receiving a command packet over a radio frequency communication link and determining whether additional processing of the command packet is needed. Based on the determination, the technique includes selectively communicating an indication of the command packet over an infrared communication link and communicating an indication of the command packet over the radio frequency communication link.

A computer system having a display housing and detachable a base housing. The base housing may include a keyboard that can communicate with the display housing via a wired interface or a wireless interface. The keyboard may also include a rechargeable battery. When the keyboard communicates with the display housing using the wired interface, a controller within the keyboard may cause the battery to be charged using a power signal available via the wired interface.

Embodiments disclosed herein include a power monitor and controller which are used to control the operation of a voltage regulator depending on an operating mode or state of a load device, such as a hard disk drive. By controlling the voltage regulator in this manner, voltage regulator efficiency may be improved for any load condition, thus reducing power losses in the system.

An optical drive may include drive electronics and wake circuitry. The drive electronics may be arranged to operate the optical drive when in a powered mode. The wake circuitry may be arranged to generate a wake signal when the drive electronics are in an unpowered mode and when a button is pushed on the optical drive or optical media is inserted into the drive. An interface to the optical drive may include a line to carry the wake signal from the wake circuitry. A host may house the optical drive and communicate with optical drive via the interface.
摘要:
An audio data stream from a processing system may be buffered to allow low power states in the processing system during audio playback. An audio buffer may be provided external to the processing system and between the processing system and an audio codec. The audio buffer may also shift to an alternate audio data interface mode when the processing system is in the low power state. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

The present disclosure provides voltage regulator configured to exchange commands and data with a power management engine. A method according to one embodiment may include generating, by a voltage regulator, at least one state signal indicative of the operational parameters of the voltage regulator; transmitting, by the voltage regulator, the at least one state signal to a power management engine; generating, by the power management engine, at least one power management signal based on, at least in part, the at least one state signal; transmitting, by the power management engine, the at least one power management signal to the voltage regulator; and controlling the operation of the voltage regulator based on, at least in part, the at least one power management signal. Of course, many alternatives, variations and modifications are possible without departing from this embodiment.
