Portable electronic device having high and low power processors operable in a low power mode

摘要

A computer system has a main display attached to a computer chassis. The computer chassis includes a high power, high performance main processor running applications on a first operating system platform. The auxiliary display module has a low power, low performance auxiliary processor, a small touch-screen display and a keypad. The main processor interfaces with a keyboard on the upper surface of the chassis and a main display. In a high power mode, there is no display and keypad input in the auxiliary display module. In a power sleep mode, power is removed from the first processor, the main display and many of the components in the computer chassis. However, key functions, such as email, a contact list, and an appointment calendar can be accessed using the auxiliary display module. In a low power mode, the main display shuts off and many of the components in the computer chassis are powered down. However, key functions, such as email, a contact list, an appointment calendar, and a media player, can be accessed using the auxiliary display module.
