How Restarted Computer Turns On By Itself?

When your computer performs updates or slows down, reboot needs. When you do this manually or automatically, something happens that you don’t think much about. “Now that’s closed, I didn’t press the button either. How did it reopen then?”

After all, to turn on the computer, pressing the power button a mechanical force we are implementing. If our computer can do this on its own, what’s preventing it from turning on at random times when off?

First of all, when you turn off the computer, you almost say “stop” to your computer.

In this context, your computer shuts down the programs that remain open and warns you if there is a file that you did not save or if there is a different session open. When you choose to close without saving, these files will disappear and after all applications are closed your session is also closed.

After signing out of the users account, on button When you press it, the processes that started are closed one by one and after all this cleaning is finished, the power from the power supply (PSU) is cut off. In this way, the closing process we are accustomed to is realized.

The computer also shuts down when you hold down the power button. But there is a critical difference here.

As we mentioned in the previous paragraphs; shutting down applications, services, and other processes individually and sequentially in this scenario, and directly to the power source signal is sent. In this context, the computer suddenly shuts down without following any sequence.

After these two scenarios, you have to press the power button to turn on the computer.

But the computer when you reboot no such thing is needed and Windows restarts itself.

This is because of a command that comes into play when your computer is shutting down.

A device that is activated when your computer is completely shut down. ACPI command (a standard that specifies how a computer, peripherals, etc. communicate with each other about power usage) tells it to turn back on as soon as it is turned off. So far, the reset processes that we mentioned in the shutdown part take place, and the computer hardware is also like when they first opened it will be back.

In other words, your computer does the cleaning it did when it was shut down, but this time it is in your hand, as soon as it shuts down. to reopen The green light will be on for a command that will provide

In this way, a code is sent to the power supply that tells the system to restart instead of the power cut command.

PSU

This is where the crossroads between shutting down and restarting the computer arises. When you turn it off, connect the electricity to the power supply. cut off this command changes when you reboot while it’s being said.
