The computer automatically turns on after plugging in the power

Sometimes the computer is like a sense of its own, a plug in the power to start their own, often scary jump. Computer host a plug in the power will be automatically turned on, because the motherboard BIOS set up the caller's own boot.

Different bios, set the method is not the same, the following list several:

Enter the Power Management Setup (source management settings) →power Again (re-caller status), which determines the power supply when power is restored, after an accidental power outage at power-on. The set values are: Power off (keep the system shut down) power on (keep the system on) the last State (the status before the system is powered down) enters suspend/sleep mode, but if the button is pressed for more than 4 seconds, the machine shuts down. Change this option to power off!

SELECT [Power MANAGEMENT SETUP] and select [PWR Lost Resume State], which has three options. Select the [Keep off] Item, the computer will not start automatically when you call again after a power outage. Select the [Turn on] item, the computer will start automatically when you call again after a power outage. Selected [Last state], then on behalf of the power outage after the call, the computer returned to the computer before the power failure. If the computer is in the power-on state before the power off, then the call will automatically boot. Before the power off is in the shutdown state, then the computer will not automatically boot after the call.

In some BIOS [power MANAGEMENT SETUP] does not have the above [PWR Lost Resume State], can be in [Pwron after pwr-fail]→[integrated peripherals] option, two options are found: On (turn on) and off (turn off the automatic boot) and set to OFF.

Select "Power Management Setup", which has an option of "Pwron after Pw-fail" means: After the power failure, the caller automatically boot. The default setting value "Disabled", that is, the power will not automatically boot, we change the value of the setting to "Enabled", so that after the restoration of power can be automatically turned on.

Different motherboard and BIOS model corresponding to the options will be different, but all the same, English-speaking friends should not be difficult, generally in [power MANAGEMENT Setup] This option can find the appropriate settings options!

In addition, the poor quality of the power supply or motherboard may cause similar problems to occur. ATX Motherboard startup needs to detect a capacitor level signal. If the power supply can not be guaranteed to be a good one at a time, it will produce an instantaneous impact current, may make the power supply mistaken for the power-on signal, which led to a false boot.
