Abstract

A power saving and system security method for a computer system is described. A PIR (personal infrared) sensor is launched. Presence of a human body is detected by using PIR sensor and sending to a signal to a processor. When the processor decides nobody is in an effective area of the PIR sensor, a power saving and system security function is executed. The presence of a human body is continuously searched for by using the PIR sensor and sending a signal to the processor. When somebody is in the effective area of the PIR sensor, the power saving and system security function is exited by inputting a correct password.

Claims

1. A power saving and system security method for a computer system, said system including a processor, said power saving and system security method comprising the steps of:

(a) launching a personal infrared (PIR) sensor disposed in said computer and electric connecting said processor;

(b) detecting a human body by using said PIR sensor and sending a signal to said processor from said PIR sensor;

(c) executing a power saving and system security function when said processor decides nobody is in an effective area of said PIR sensor;

(d) continuously searching for a human body in said effective area by using said PIR sensor and sending a signal to said processor; and

(e) exiting said power saving and system security function by inputting a correct password when somebody is in said effective area of said PIR sensor.

2. The power saving and system security method of claim 1, after step (b) further comprising:

not executing a power saving and system security function when said processor decides somebody is in an effective area of said PIR sensor.

3. The power saving and system security method of claim 2, wherein said system security function includes a screen protection program.

4. The power saving and system security method of claim 3, wherein said power saving function includes a screen shutdown function, a hard disk shutdown function, a system sleep function, or a system standby function.

5. The power saving and system security method of claim 1, wherein said system security function includes a screen protection program.

6. The power saving and system security method of claim 1, wherein said power saving function includes a screen shutdown function, a hard disk shutdown function, a system sleep function, or a system standby function.
