Abstract

Low power email capabilities are provided for an electronic device, such as a hand-held portable computer having capability to operate an application during a low power mode. During the low power mode, portions of hardware, software, services, and/or other components of the portable computer that are not necessary for email-related operations, such as polling a server for new email, are suspended or otherwise deactivated. At least a portion of a new email is stored in a memory of a low power display module (LPDM) of the portable computer. The LPDM is provided with its own low-power processing unit, user interface, and other components to allow access to and manipulation of the stored email while other components of the portable computer remain deactivated.

4. The method of claim 3, further comprising synchronizing email contents in the memory to the storage location, after user manipulation of the email contents in the memory.

5. The method of claim 1 wherein using the email component to obtain the portion of the second email during the low power mode includes using the email component along with a selectively activated network access device of the electronic device to obtain the portion of the second email.

6. The method of claim 5 wherein the network access device is associated with the low-power processing module of the electronic device and is different from a network access device associated with the high power processing module of the electronic device.

7. The method of claim 1, wherein the memory associated with the low power processing module is a second memory and wherein the second memory is physically separate from the first memory, further comprising:

storing the portion of the first email in a first memory associated with the high power processing module;

synchronizing the portion of the first email from the first memory to the second memory;

presenting the synchronized portion of the first email from the second memory using the second display controlled by the low power processing module.

8. An article of manufacture usable for a portable 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 article of manufacture comprising:

a machine-readable storage medium having instructions stored thereon to cause a processor to process email during a low power mode, by;

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

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

transitioning the portable 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 portable 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 portable 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; and

presenting the loaded portion of the second email from the memory on a second display controlled by low power interface associated with the low power processing module, wherein the second display is physically separate from the first display and wherein the second display is viewable when the portable electronic device is in a second configuration,

wherein the portable 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.

9. The article of manufacture of claim 8 wherein the instructions for monitoring for the event representative of the transition to the low power mode includes instructions for monitoring for a time interval when the transition to the low power mode is scheduled to occur.
