Abstract
A keyboard operatively couplable to an information handling system comprising a keyboard microcontroller on a keyboard printed circuit board (PCB) and a keyboard power management unit operatively coupled to the keyboard microcontroller. An input actuator including a window formed through the input actuator with an electrochromic film layer formed under the input actuator wherein a portion of the electrochromic layer is viewable through the window and an opaque colored film layer formed under the electrochromic film layer such that a voltage pulse passing through the electrochromic film layer changes a state of opacity of the electrochromic film layer and actuation of the input actuator changes a function state of software or hardware at the information handling system that is controlled by the input actuator. The electrochromic film layer state of opacity indicates the function state of software or hardware through the window of the input actuator.
