What's going on when the computer is plugged in?

If the computer appears to power on the automatic boot situation, there are two possibilities, one is set up the caller power function;

1, call power-on function and power management, may be in the BIOS setup items in the call to open the function of automatic power-on, when a plug in AC power, the computer will automatically start.

If you do not want to use this feature, turn it off.

The solution is as follows:

When you turn on the computer, press Del to enter bios--"Powermanagementsetup" or "powermanagementfeatures" (Power management Settings)--"apmconfiguration" ——— Restoreonac/powerloss ", this option has three sub options," PowerOn "(power-on)," Poweroff "(Shutdown)," LastState "(back to the last shutdown state). The computer uses these three options to manage the state of the computer when it is powered on. If you do not want to use this feature, set to "Poweroff" (shutdown).

2, if it is a power problem, there are two possible.

One is that the power supply itself is less capable of anti-interference, AC power connected to the instantaneous interference caused its main circuit to start work; the second is from the motherboard ps-on signal quality is poor, especially in the power of the moment, the signal from the low level to the high level of the delay is too long, until the main power supply is ready, the signal has not become a high level, Misleading the ATX power supply main circuit.
