An example non-transitory computer-readable medium includes instructions to monitor a time-averaged power consumption of a computing device that includes a plurality of power-consuming components including a processor, and compare the time-averaged power consumption to a first threshold to detect if the time-averaged power consumption exceeds the first threshold. In response to detecting that the time-averaged power consumption of the computing device exceeds the first threshold, the instructions are to decrease an operational power of the processor from a normal operating power, and start monitoring an instantaneous power consumption of the computing device to determine whether to make a further decrease or an increase to the operational power of the processor.

Surge recovery with processor power control

An example non-transitory machine-readable storage medium storing machine-readable instructions which when executed cause a processor to obtain stored bits stored on a flash memory, each of the stored bits in a set state or an unset state. The processor further obtains target bits, each of the target bits in the set state or the unset state, wherein each target bit corresponds to a stored bit to update the stored bit. The processor further determines whether, for one stored bit in the set state, the corresponding target bit is in the unset state. When the determination is positive, the processor sets the stored bits to the unset state and, after setting the stored bits to the unset state, updates the stored bits to match the corresponding target bits. When the determination is negative, the processor updates the stored bits to match the corresponding target bits.

Updates to flash memory based on determinations of bits to erase

An example of an apparatus is provided. The apparatus includes a power supply to connect to a power source. The power supply is to receive and to distribute a total power from the power source. The apparatus further includes a first device to receive a first portion of the total power from the power supply. The apparatus further includes a second device to receive a second portion of the total power from the power supply. A sum of the first portion and the second portion is the total power. In addition, the apparatus includes a controller to control the second device, wherein the controller is to determine the total power demanded by the first device and the second device. The controller is to reduce the second portion of the total power and to restore the second portion of the total power.

Power management systems

A circuit for identifying a power supply may include a voltage divider to divide an identification voltage from the power supply. The output of the voltage divider is electrically coupled to an adapter identification pin of a controller to identify the power supply.

Power supply identification

Example systems relate to power monitoring and reduction processes. An example system may include a modular computing device including a plurality of universal serial bus (USB) ports and a power supply unit coupled to the modular computing device. The example system may further include an embedded controller coupled to the power supply unit and to the plurality of USB port. The embedded controller may monitor a level of power consumed by the system and determine whether a surge event has occurred in the system. In response to the determination that the surge event has occurred, the embedded controller may determine whether an agency event has occurred in the system and initiate a power reduction process in response to the determination.

Power monitoring and reduction

Example implementations relate to balancing a power load among USB ports. For example, an apparatus according to the present disclosure, may include a plurality of USB ports, and an embedded controller coupled to the plurality of USB ports. The embedded controller may determine that a first device is coupled to a USB port of the plurality of USB ports, and determine a power draw of the first device relative to a type of the USB port. The embedded controller may balance a power load among a remainder of the plurality of USB ports based on the power draw of the first device relative to the type of the USB port.

Balancing a power load among USB ports

In one example in accordance with the present disclosure, a power management device is described. The power monitoring device includes an input line to receive input power information from a power supply device. The input power information is indicative of a level of input power from the power supply device. A controller of the power monitoring device determines a scaling amount of the input power information based on a power rating of the power supply device. A programmable scaling device scales the input power information based on the scaling amount to generate output information and an output line passes the output information to a set of recipient devices.

Input power scaling of power supply devices

Example implementations relate to dual rail circuitry using FET pairs. For example, a circuit according to the present disclosure may include a first field-effect transistor (FET) pair coupled to a dual rail circuitry, a second FET pair coupled to the dual rail circuitry, and a controller coupled to the first FET pair and the second FET pair. The controller may switch a power supply to the dual rail circuitry using the first FET pair and the second FET pair. The dual rail circuitry may provide a power supply to a computing device from a first power supply coupled to the first FET pair or a second power supply coupled to the second FET pair.

Dual rail circuitry using FET pairs

Examples herein disclose determining whether a computing device should implement a zero watt state according to an engagement of a button. The examples disconnect a power source to the computing device based upon the determination the computing device should implement the zero watt state.

Determination of a zero watt state for implementation

According to examples, an apparatus may include a power circuit to transmit standby power to a device, a memory associated with the device to maintain first configuration data and second configuration data and a battery to provide backup power to the device. The device may, following a loss and a recovery of the standby power to the device, determine whether the backup power was lost during the loss of the standby power. The device may also, based on a determination that the backup power was lost during the loss of the standby power, read the first configuration data or may, based on a determination that the backup power was not lost during the loss of the standby power, read the second configuration data. The device may further apply the read one of the first configuration data or the second configuration data to configure the device.

Backup power supply based configuration data application

An example system includes a processor. The system also includes a peripheral interface that includes a controller communicatively coupled to the processor. The controller is to request information from a plurality of devices connected to the peripheral interface prior to the processor requesting the information. The controller is to provide the information to the processor.

Connected devices information

Examples of an apparatus, method, and instructions included on a machine-readable non-transitory storage medium are disclosed herein. In an example of the method, a first state is provided to enable a camera to record an image, a second state is provided to disable the camera, and a third state is provided to permit the camera to be enabled and disabled. Also in this example of the method, a button is actuated in the third state to an on position to enable the camera to record an image or an off position to disable the camera. Additionally in this example of the method, a signal is generated via an input device in the on position of the button to enable the camera to record an image or disable the camera.

Additionally, the examples configure the device based on the configuration data, wherein the device is configured prior to initialization of the computing system.
