In one example in accordance with the present disclosure, an electronic device is described. An example electronic device includes a processor, a port to receive a connector of a peripheral device, and a power supply. An example power supply is to supply power to the processor and the peripheral device when connected to the electronic device. The example electronic device also includes an electronic device controller. The electronic device controller is to alter an amount of power from a first value to a second value to supply to the peripheral device based on an amount of power available from the power supply and a lower threshold power level that enables data communication from the peripheral device. The example electronic device also includes a power delivery controller. The power delivery controller is to provide the amount of power having the second value to the peripheral device based on an output from the electronic device controller.

Peripheral device power

Example implementations relate to motion based power states. For instance, in an example an electronic device includes input components, a motion detector separate from the input components, the motion detector to detect over a period of time an amount of motion of an object proximate to the electronic device, and a controller to compare the detected amount of motion of the object to a motion threshold, and alter a power state of an input component of the input components based on the comparison.

Motion based power states

An example power adaptor includes a converter and a circuit to detect an overcurrent event at the converter and to pause power output of the converter when the overcurrent event is detected. The circuit is further to count a number of overcurrent events at the converter within a time period. The circuit is further to compare the number of overcurrent events to a threshold number and to switch off the power output of the converter when the number of overcurrent events passes the threshold number.

Power control with detection of overcurrent events

Example implementations relate to touch input detection. In some examples, a computing device may include a touch sensitive interface, a processing resource, and instructions executable by the processor. The instructions may be executable by the processor to cause the processor to detect a period of inactivity of the touch-sensitive interface; activate a one-dimensional scan for a touch input on the touch-sensitive interface in response to detecting the period of inactivity; and activate a two-dimensional scan for a touch input on the touch sensitive interface in response to detecting the period of inactivity.
