Claims20
An apparatus, comprising:
- a display controller to control illumination of a display with a display control signal in response to a power transition of the apparatus between a sleep state and an active state;
- and
- a keyboard controller coupled to the display controller, wherein the keyboard controller is to control a plurality of illumination devices individually coupled to a plurality of keys of a keyboard to produce a plurality of patterns in response to receipt of the display control signal, wherein a first pattern of the plurality of patterns is indicative of a power transition from the sleep state to the active state and a second pattern of the plurality of patterns is indicative of a power transition from the active state to the sleep state.
A system, comprising:
- a display;
- a keyboard comprising a plurality of keys and a plurality of illumination devices coupled to the plurality of keys, and
- a controller coupled to the display and the keyboard, wherein the controller is to control illumination of the display and the plurality of illumination devices to produce a pattern visible on the display and the keyboard in response to a received display control signal, wherein the display control signal is indicative of a power transition between a sleep state and an active state of the system and wherein th pattern visible on the display and the keyboard indicates the power transition is from the sleep state to the active state or from the active state to the sleep state.
A method, comprising:
- receiving, by a controller, a display control signal to control illumination of a display, wherein the display control signal is indicative of a transition between an active state and a sleep state;
- determining, by the controller, a pattern for a plurality of illumination devices of a keyboard based on whether the display control signal is indicative of a transition from the active state to the sleep state or the sleep state to the active state, wherein the plurality of illumination devices are individually coupled to a plurality of keys;
- and
- controlling, by the controller, the illumination of the display and the plurality of illumination devices in accordance with the pattern.
