A terminal setting parameter adjustment method and apparatus are provided. The method includes, after an application program in a terminal is started, displaying a setting control in a display area of the terminal; after the setting control receives a call instruction, modifying a current parameter value of a first setting parameter to a latest parameter value that is of the first setting parameter and that is to be used when the application program runs, and when the application program is exited, modifying a current parameter value of the first setting parameter to the parameter value that is of the first setting parameter and that is obtained before the application program is started.

A computer-implemented method for controlling time out of a device is disclosed according to an aspect of the subject technology. The method comprises determining whether at least one content-viewing criterion is satisfied; if the at least one content-viewing criterion is satisfied, then preventing the device from timing out upon expiration of a time-out period; and if the at least one content-viewing criterion is not satisfied, then timing out the device upon expiration of the time-out period.

Systems and methods employ an external energy storage device (e.g., intelligent battery pack) interposed between a an information handling system (IHS) and its AC-to-DC adapter. The information handling system may be a fixed compute system, may lack an internal battery and/or may execute an operating system that does not have power management capability. The external energy storage device provides power and power state information to the IHS, e.g., that is based on state of charge (SOC) of the battery and/or absence/presence of AC power. IHS may perform one or more actions based on the power state information such as automatically save data and shutdown when notified AC power is lost and/or SOC is low, and may automatically restart and restore saved data when notified AC power is restored and/or SOC is sufficiently high. The external energy storage device may actively signal or command the IHS to act or may passively supply power state information and let the IHS decide how to act. The information may be provided as different power supply identifier (PSID) values or other types of analog values corresponding to different current levels on a single conductor of a single cable between the external energy storage device and IHS, or may be included in USB vendor-defined messages sent on the single cable.

Controllers that control a building's state functions can be controlled by a master controller that the controllers choose themselves. The master controller communicates with the controllers and sensors to determine when a building state should change. When the building state should change, the master controller or another controller determines the device or devices that need to modify state values of the building, and send messages to the devices so that they can change building state. If the master controller has a fault, the working controllers can choose another master controller. When a sensor indicates that a building state needs to be changed the master controller determines which device should change state, then tells the controller that is attached to the device.

A cradle apparatus detects spatial distances from target objects positioned in adjacency to the cradle apparatus, and communicates with a mobile communications device for selectively powering off/on the visual display of the mobile communications device based on its distance from a target object. The cradle apparatus includes a cradle assembly, at least one distance sensor, and sensor support circuitry. The cradle assembly is configured for cradling the communications device and displaying a visual display of the communications device as cradled by the cradle assembly, optionally at an oblique angle relative to a support surface. Each distance sensor is positioned by the cradle assembly for detecting the relative distance of select objects positioned in adjacency to the visual display. The sensor support circuitry communicates each distance sensor to a switch or circuit board for powering off or powering on the visual display depending on its distance from the target object.

A power-saving method for performing power consumption management on an electronic device is provided. The power-saving method includes determining whether a software application executed on the electronic device relates to a network service or not; and disabling at least one system-activating event provided by the software application for the electronic device when the software application relates to the network service and when the network service is unavailable to the electronic device.

In one example an electronic device comprises a power supply comprising an operating power rail and a standby power rail, a processing platform capable to switch between an operating power state and at least one low power state, a switch to selectively couple a power input of the processing platform to one of the operating power rail or the standby power output rail and logic, at least partially including hardware logic, to activate the switch based at least in part on the operating state of the processing platform. Other examples may be described.

Methods, apparatus, and processor-readable storage media for automated device power conservation using machine learning techniques are provided herein. An example computer-implemented method includes obtaining usage-related data from one or more processing devices; determining at least one usage pattern for the one or more processing devices by processing the obtained usage-related data using one or more machine learning techniques; automatically generating, based at least in part on the at least one determined usage pattern, instructions pertaining to controlling one or more power states of the one or more processing devices; and performing at least one automated action based at least in part on the generated instructions.
