Abstract:
1. A power saving mode for an electronic device with a microprocessor and a telematics circuit, comprising: a power source; a microprocessor and a telematics circuit powered by the power source; a power switch on a power distribution line between the power source and the microprocessor and the telematics circuit for energizing or powering off the telematics circuit and the microprocessor; a power latch for controlling the power switch at a power switch control based on a control value sent from the microprocessor to the power latch; and an alarm with an external sensor powered by the power source with a configuration value sent by the microprocessor for producing a signal alarm to the power latch; wherein the power switch is closed to energize the microprocessor and the telematics circuit when the signal alarm reaches the control value, and wherein the power switch is opened to power off the microprocessor and the telematics circuit at the request of the power latch controlled by the microprocessor.
