1. A power profile diagnostic system, comprising:

  • a power rail;

    a plurality of subsystems that are coupled to the power rail; and

    a controller that is coupled to the power rail and to a power profile database, wherein the controller is configured to;

    prevent power from being supplied through the power rail to a first subset of the plurality of subsystems while a second subset subsystem of the plurality of subsystems perform a predefined operation using power from the power rail;

    monitor the power rail and determine a power consumption profile of the second subset of the plurality of subsystems during the predefined operation;

    compare the power consumption profile to a predetermined power profile that is stored in the power profile database in association with the predefined operation;

    determine that a difference between the predetermined power profile and the power consumption profile is indicative of a malfunction of the second subset of the plurality of subsystems; and

    provide a malfunction report for display in response to determining that the difference between the predetermined power profile and the power consumption profile is indicative of the malfunction of the second subset of the plurality of subsystems.
