The technical problem this invention aims to solve is to provide a circuit for powering on / off electronic devices using function keys. This circuit utilizes the device's existing key combinations to power on and off the entire device, eliminating the need for a separate power switch. The circuit for powering on / off electronic devices includes a power input unit, a key triggering unit, a main switch unit, a level holding unit, a voltage regulator output unit, and an MCU main control unit. Electronic devices with this circuit do not require a separate power button, do not increase structural openings or hardware costs, improve the overall aesthetic design of the device, and directly utilize the device's built-in key combinations to power on and off. The circuit is stable and prevents accidental touches; unidirectional diode isolation and resistor biasing prevent interference-induced accidental power-on / off, ensuring stable and reliable operation. The circuit hardware requires no special components; all components used are very common discrete components, which are extremely inexpensive, and there is almost no leakage current after power-off, significantly improving the battery life of battery-powered devices.
