This article shows you an example analysis of Intel pressing the power button to shut down the computer without harming the hardware and possibly losing data. The content is concise and easy to understand, which can definitely brighten your eyes. I hope you can gain something through the detailed introduction of this article.

Press the power button directly to turn it off without harming the computer?

On July 28th, Intel gave a complete answer to this question.

It is reported that at the beginning, the computer will not turn itself on and off.

A long time ago (yes, in that hot-blooded era), computers did not have the ability to turn themselves on and off.

So when a user clicks shutdown in Windows, instead of the familiar computer shutting down automatically, the message is "you can safely shut down the computer." At this point, the user needs to manually press the power button on the fuselage, "click", just like pulling the plug to completely cut off the power supply.

Until now, the computer fans, hard drives, optical drives and other accessories will stop running.

This situation did not change completely until the introduction of the ACPI (Advanced configuration and Power Interface) specification in 1997.

The new standard no longer needs physical switches to cut off the power supply, realizes the control of the power supply by the operating system, and realizes the advanced power management functions such as soft shutdown and sleep.

Will it cause harm if you press the power button to force the shutdown?

For a long time, everyone's oral experience was "harmful, try not to do so".

This statement is quite true in "ancient times", because the switch button of this kind of computer is equivalent to pulling the plug directly. At the moment you press the power switch, the computer does not know whether the hard disk should read or write. It is equivalent to experiencing an accidental power outage, which may cause data loss or even damage the hard drive.

But today, is it true that the power management specification has long been popular and evolved to a more advanced version?

The answer is no, because pressing the power button to force the shutdown looks like suddenly cutting off the power, but in fact, when the computer receives the signal of a long press to shut down, it will trigger a series of hardware shutdown flows. gradually disconnect the power of each accessory in accordance with the regulations.

This process is no different for hardware than shutting down the computer in Windows, the biggest difference is that it ignores Windows itself and running software-if there are unsaved documents or other data, it may be lost.

Therefore, directly pressing the power button to shut down does no harm to the hardware, and may damage or lose the operating system and software data, but the forced shutdown generally occurs when there is something wrong with the software system, so there is no need to worry too much about this problem.

The above is an example of Intel pressing the power button to shut down the computer without harming the hardware and possibly losing data. Have you learned the knowledge or skills?
