Patent ID: 7500127

Claim:
A method usable for an electronic device having a lid that has a display screen located on an inside surface of the lid and a low power display located on an outside surface of the lid, the method comprising: obtaining data indicative of parameters to operate a low power mode application during a low power mode of the electronic device, the low power mode application corresponding to but different from a full power mode installed application that operates during a full power mode of the electronic device; initiating transition to the low power mode in response to a closing of the lid of the electronic device and in response to operating, while the lid is closed to cover the display screen on the inside surface of the lid, an interface on the low power display located on the outside surface of the lid; using the obtained data to selectively suspend or terminate applications and operating system tasks running on the electronic device, wherein the suspending or terminating includes suspending or terminating the full power mode installed application; activating the low power mode application; using the obtained data to selectively deactivate elements of the electronic device during the low power mode; maintaining at least one element that is usable by the low power mode application during the low power mode activated while the at least one element is used by the low power mode application during the low power mode; deactivating the at least one element otherwise during operation of the low power mode application in the low power mode; and interacting between the low power mode application and the full power mode installed application, during the low power mode, using an application program interface (API).
