First Claim
1. A computer system, comprising:
- a power supply device, providing an operation voltage;
a satellite positioning chip, receiving a satellite positioning signal through an antenna;
a communication interface, electrically connects with the satellite positioning chip;
a control chip, receiving the operation voltage, controlling to supply source voltage to the satellite positioning chip, and retrieving and processing the satellite positioning signal through the communication interface; and
an actuation element, electrically connecting with the control chip, wherein when the computer system is at a system power-off state and the actuation element is triggered, the control chip supplies source voltage to the satellite positioning chip so as to retrieve and process the satellite positioning signal.

Abstract
A computer system is operative to receive a satellite positioning signal at a system power-off state. The computer system includes a power supply device, a satellite positioning chip, a communication interface, a control chip and an actuation element. The power supply device provides an operation voltage. The satellite positioning chip receives the satellite positioning signal through an antenna. The communication interface electrically connects with the satellite positioning chip and the control chip. The control chip receives the operation voltage, supplies source voltage to the satellite positioning chip, and retrieves and processes the satellite positioning signal through the communication interface. The actuation element electrically connects with the control chip. When the computer system is triggered by the actuation element under the system power-off state, the control chip supplies source voltage to the satellite positioning chip, so as to retrieve and process the satellite positioning signal.
