Portable electronic device having high and low power processors operable in a low power mode
First Claim
1. A computer system, comprising:
- a computer chassis comprising a base and a lid for the base;
a keyboard mounted on an inner surface of the base for the chassis;
a main display mounted on an inner surface of the lid;
a first processor operatively coupled to the keyboard and main display;
an auxiliary display mounted on an outer surface of the lid;
a keypad mounted on the outer surface of the lid;
a second processor having less computing performance than the first processor and consuming substantially less power than the first processor, the second processor being operatively coupled to the auxiliary display and keypad; and
a power controller operatively coupled to the first and second processors, the power controller causing the computer system to operate in either a high power mode or a low power mode.

Abstract
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.

65. A method of operating a computer system having a first processor operatively coupled to a main display and a second processor operatively coupled to an auxiliary display, the first processor having substantially higher performance and substantially higher power consumption than the second processor, the method comprising:
-
in a high power mode, applying power to the first processor so that the first processor can function with the main display in the high power mode; and
in a low power operating mode, removing power to the first processor and applying power to the second processor so that the second processor can function with the auxiliary display in the low power operating mode. - View Dependent Claims (66, 67, 68, 69, 70, 71, 72, 73)
