Abstract
Audible noise related to power state transitions of an information handling system processing component, such as the central processing unit, is reduced by randomizing the time between power state transitions. Random power state transitions are managed by an operating system module that tracks the transitions and selects random times for subsequent transitions within a predetermined time range. Alternatively, an arbitrating circuit intercepts power state transition commands and arbitrates their communication at random times. Random power state transitions reduces audible noise by spreading the frequency of the noise-causing power transition events over a wider band.
