NOTEBOOK COMPUTER AND POWER-SAVING METHOD THEREOF
First Claim
1. A notebook computer comprising:
- an infrared sensor to detect presence of a human body within a predetermined range of the notebook computer, and output a level signal according to the detecting result;
a south bridge chip to receive the level signal from the infrared sensor, and output the level signal;
a basic input/output system (BIOS) chip storing a sleep signal and a wake-up signal, wherein the BIOS chip is operable to read the level signal from the south bridge chip and selectively output the sleep signal or the wake-up signal according to the level signal;
a memory to receive the sleep signal or the wake-up signal from the BIOS chip and store the sleep signal or the wake-up signal; and
a central processing unit (CPU) to read the sleep signal or the wake-up signal from the memory, and control the notebook computer to enter into a sleep state or a wake-up state.

Abstract
The infrared sensor detects whether presence of a human body within a predetermined range of a front of the notebook computer, and outputs a level signal according to the detecting result. The south bridge chip receives the level signal from the infrared sensor and outputs the level signal. The basic input/output system (BIOS) chip storages a sleep signal and a wake-up signal, and reads the level signal from the south bridge chip and selectively outputs the sleep signal or the wake-up signal according to the level signal. The memory receives the sleep signal or the wake-up signal from the BIOS chip and stores the sleep signal or the wake-up signal. The center processing unit (CPU) reads the sleep signal or the wake-up signal from the memory and controls the notebook computer to enter into a sleep state or a wake-up state.

6. A power-saving method for a notebook computer, the power-saving method comprising:
-
detecting whether a human body is present within a predetermined range of the notebook computer via an infrared sensor, and outputting a level signal to a south bridge chip based on the presence or non-presence of a human body; outputting a sleep signal or a wake-up signal to a memory from a basic input/output system (BIOS) chip, according to the level signal outputted from the south bridge chip; and reading the sleep signal or the wake-up signal stored in the memory according the level signal and controlling the notebook computer to enter into a sleep state or a wake-up state. - View Dependent Claims (7, 8, 9, 10)
