An energy-saving electronic device and an energy-saving method for use with the same are provided. Under a triggering condition by an input signal, a trigger module produces a control pulse that urges a system-board module switch to be switched on, such that a microprocessor or central processing unit (CPU) operates with power supplied from a power module through the system-board module switch, and forwards a control signal to the trigger module for allowing the system-board module switch to be in a stable switching-on condition. When the input signal ends and thus the control pulse terminates, the microprocessor or CPU stops sending the control signal to the trigger module, and the system-board module switch is adapted to be switched off with no power being provided from the power module to the microprocessor or CPU, thus making the microprocessor or CPU in a complete power cut-off mode instead of a sleep mode in favor of power saving.
