Embodiment Construction

[0018] figure 1 The illustrated computer system 100, which may be in a desktop style, or a laptop style, or any other suitable form, illustrates an exemplary embodiment of the present invention.

[0019] A CPU (Central Processing Unit, 112) is a typical data processing component that executes program instructions stored in memory. Random access memory (RAM, 114 ) is a typical memory component used to store data and program instructions accessed by CPU 112 . Hard disk drive 108 is a typical mass storage device used to store data and programs. figure 1 Particular blocks of logic 104, 106 relevant to the discussion of the present invention are shown. The remaining system logic is represented as other system logic 116 . The aforementioned components typically coordinate their actions and communicate data by asserting control signals on control lines and transmitting data on a data bus. Most of these signal and data lines are shared by figure 1 represented by the system bus 11...

Abstract

A power management component in a computer system includes an imaging device operatively connected to a computer. When the computer has entered a low power state, the imaging device can continue to operate to detect motion in its field of view. When 'enough' motion is detected, the imaging device can signal the computer in a manner as to transition the computer to a full power state. In another aspect of the present invention, the imaging device can determine that there has been insufficient motion for a predetermined period of time and initiate a transition of the computer to a low power state.

Description

technical field [0001] The present invention relates generally to computers, including laptop computers and desktop computers, and particularly to power management in computers. Background technique [0002] Laptop computers, commonly referred to as notebook computers or simply "notebooks", have become a popular form of computer. Notebook computers are lightweight and have processing and storage capabilities comparable to desktop systems, and are thus a real and viable alternative to desktop computers. However, a serious disadvantage in notebook computers is the limited power capacity of their batteries. Therefore, power management in notebook computers has become important to battery life. From the viewpoint of reducing power consumption, reducing power bill, etc., power management in desktop systems is also receiving increasing attention. [0003] Power management refers to the different power states of a system, whether it is a notebook computer or a desktop unit. A p...
