1. A method usable for an electronic device that can operate in a standby mode, a low power mode, and a higher power mode, wherein the standby mode uses less power than the low power mode and the low power mode uses less power than the higher power mode, the method comprising:

  • in the higher power mode, operating an email application to obtain at least a portion of a first email under control of a first processor in a high power processing module;

    displaying the portion of the first email on a first display controlled by the high power processing module using the first processor, wherein the first display is viewable when the electronic device is in an open configuration;

    transitioning the electronic device to the standby mode, wherein transitioning includes deactivating or reducing power to the high power processing module;

    monitoring for an event representative of a transition from the standby mode to the low power mode;

    in response to detecting the event, activating an email component to operate during the low power mode;

    deactivating at least a first component of the electronic device that is to be unused for obtaining at least a portion of a second email during the low power mode;

    activating at least a second component of the electronic device that is to be used in conjunction with the email component for obtaining the at least a portion of the second email during the low power mode;

    using the email component to obtain the at least a portion of the second email during the low power mode;

    deactivating the second component after the at least a portion of the second email is obtained;

    loading the portion of the second email to a memory associated with a low power processing module separate from the high power processing module by a second processor in the low power processing module; and

    using the second processor, displaying the loaded portion of the second email from the memory on a second display controlled by the low power processing module, wherein the second display is viewable when the electronic device is in a closed configuration,wherein the electronic device has a lid and the first display is located on an inside surface of the lid, and wherein the second display is physically separate from the first display and the second display is located on an outside surface of the lid.
