Abstract: Examples disclosed herein relate to changing power states of a device. Example devices include an input/output port to couple to a component to receive an actuation event. A chipset processor of the device may determine a power state of the device; in response to a determination that the power state is an ultra-low power state, determine a component identification (ID) of the component; fetch a reference ID from non-volatile memory; and compare the determined component ID with the reference ID. The chipset processor of the example device to transmit a signal to change the power state of the device in response to a match between the determined component ID and the reference ID and reception of signals indicative of an actuation event.
