Patent ID: 8650418

Claim:
A power-saving management method for a computer peripheral device, suitable for stopping an operation of at least one functional electronic element and a plurality of array antennas of the computer peripheral device when the computer peripheral device enters into a power-saving mode, the method comprising: activating a sensor of the computer peripheral device, and detecting a first environmental parameter value of the computer peripheral device by the sensor; acquiring a second environmental parameter value, and determining whether a change occurs between the first environmental parameter value and the second environmental parameter value detected by the sensor or not; activating the functional electronic element and the array antennas to operate when the first environmental parameter value is changed, and detecting whether the computer peripheral device performs a signal transmission with a computer host or not within a counting time; and resetting the sensor, if the computer peripheral device does not perform any signal transmission after the counting time elapses, recording the second environmental parameter value as the new first environmental parameter value by the sensor, and causing the computer peripheral device to enter into the power-saving mode once again.
