CONTROLLER

摘要

A first controller can provide system state information and a second controller can receive the system state information. The second controller can be programmed to control the state of a component. The state of the component can be based on information programmed in the second controller and the system state information. The component can include an off state and an operating state indicated by a signal from the second controller.

1. A computing system comprising:
an audio amplifier; and a controller to control a power state of the audio amplifier based on diagnostic information of the computing system and the computing system power state information; and the audio amplifier to include an off state and an operating state independent of whether the computing system is in a sleep state and indicated by a signal from the controller; wherein the controller is to monitor diagnostics of the computing system during the system sleep state and with the audio amplifier in the off state; and wherein, while the computing system remains in the sleep state, based upon detecting a diagnostic error condition, the controller is to transition the audio amplifier from the off state to the operating state and to send a signal to the audio amplifier to cause an audio indication of the detected diagnostic error condition.
