Abstract

The invention discloses a computer starting circuit capable of preventing misoperation and relates to the technical field of the computer starting circuit, wherein the computer starting circuit comprises a south bridge chip, a power button, an ATX power supply and a double-D trigger, and the first foot of the double-D trigger is in parallel connection with the fourth foot of the double-D trigger via the second foot of the double-D trigger and is connected with the ninth foot of the ATX power supply; the fourteenth foot of the double-D trigger is connected with the ninth foot of the ATX power supply; the ninth foot of the ATX power supply is connected with the power button via a first resistor, and the ninth foot of the ATX power supply is connected with an input end of a voltage stabilizer, and an output end of the voltage stabilizer is connected with an input end of a triggering circuit; the third foot of the double-D trigger is connected with the power button; the fifth foot of the double-D trigger is connected with the first port of the triggering circuit, and the power button is connected with the second port of the triggering circuit; the third port of the triggering circuit is connected with a base of a triode, and a collector of the triode is connected with the fourteenth foot of the ATX power supply. The computer starting circuit of the invention can be used for solving the problem that current computer is overturned wrongly.

Description

technical field [0001] The invention relates to the technical field of computer start-up circuits; in particular, a computer start-up circuit for preventing malfunctions. Background technique [0002] With the popularization of computers, people are increasingly inseparable from computers. Whether they are living or working, computers have become an indispensable tool for people. The existing computer power-on circuit is composed of an RC charge-discharge circuit and a power-on level output circuit. When the computer is turned on, the power-on level output circuit will output a level from low to high under the action of the RC charge-discharge circuit. This starts the computer motherboard. However, in the process of using the computer, sometimes the power supply will be cut off instantly. Since the capacitor in the RC charging and discharging circuit has no time to discharge the electricity at the moment of power off, when the power supply is turned on again after a momenta...
