When the computer is turned off, will it affect the power outage and the call?

There are several aspects of the impact on computers, and we analyze them from these two points:

First, from the impact of power outages on computer hardware.

When the computer suddenly loses power, the power supply parts in the computer are cut off, and the rotating parts stop, such as various fans, but it doesn't matter. The most pitiful thing is our hard drive.

The speed of the hard drive is 5400 or 7200 or higher. In the event of a sudden power failure, the head has no power to maintain, so it cannot be suspended on the platter, and it collides violently with the platter, causing damage to the platter and damaging the data recorded by the platter. In short, the impact of a power outage on a hard drive can range from no impact or data loss to bad sectors (frequent power outages).

For hard disks, it should also be noted that today's hard disk shockproof and anti-power-off damage technology is still relatively advanced, when the hard disk is not reading data, the head will automatically return to a safe place, even if the power is suddenly cut off, there will be no damage to the hard disk, okay.

Second, from the impact of power outages on the soft aspects of computers.

When the general work you are working on is not saved and backed up in time, a sudden power outage will very likely cause you to lose all the work you have done before. Sometimes the losses can be very significant.

If it's a notebook, it usually doesn't matter.

No, as long as the phone is turned off, there is no problem, and there will be a certain impact if it is not turned off.

Summary. <>

Dear, hello, I'm glad to have your question, to help you find the following answers: Will the desktop computer automatically turn on after a power outage, and the power state before the power outage is pro, "As long as the power is off, whether it is an active shutdown or a sudden power outage, the computer will not automatically turn on after the call, consulting records · on 2022-08-19

Will the desktop computer automatically turn on when the call comes back after the power failure, and the state of power on before the power failure.

Dear, hello, I'm glad to have your question, to help you find the following answers: Will the desktop computer automatically turn on when the phone comes after a power failure, the boot state before the power outage, "As long as the power is off, whether it is an active shutdown or a sudden power outage, the computer will not automatically turn on after the call, pro, you need to press the power on button again to restart the operation." Some hard disk protection design is not good, and the system will run abnormally due to sudden power failure, or even files will be destroyed and cannot be turned on.

Dear, at this time, if it is a brand machine, there will be a one-click recovery function, you need to restore the system with a one-click recovery, and you can completely restore it to the complete, clean and fast state when it just left the factory.

Normally, it won't break.

A power outage isn't a big deal, unless you're doing a disk operation like ghost.

But the key is that when a sudden call comes in, there will be one or more surges in the current, and the current and voltage will increase instantaneously.

Therefore, if it rarely happens, you can ignore it, and if it happens frequently, it should be equipped with a voltage regulator or UPS with voltage stabilization function.

A sudden power outage of the computer is a forced shutdown.

machine, forced shutdown has the following damage to the computer.

1；Corrupt disk.

Forced shutdown undoubtedly hurts the computer disk the most, forced shutdown causes the disk head to fail to reset, you need to find the track when you turn on again, such as writing files, forced shutdown will lead to file loss, or hard disk damage.

2；impact on the system;

Forced shutdown will cause the system to appear blue screen, black screen, error** and other problems, forced shutdown occurs The above error is recommended to restore the system to ensure the normal operation of the computer.

3；Resulting in data loss.

Forced shutdown results in the loss of data from parts of the software currently running on the computer, such as office documents and other data programs. It may also cause the software to be corrupted and unusable.

4；Burned-out parts.

Forced shutdown will cause various data conflicts, which will generate high-voltage arcs to the internal parts of the chassis, which will affect some computer parts and cause damage.

5；Reduced hardware life.

Forced shutdown skips the operation of restoring the configuration of software and hardware when the computer is shut down, thereby damaging the life of the hardware, such as the computer motherboard, graphics card, and other data-based components.

Dear, don't worry, it won't damage your computer, it will just lead to the loss of unsaved files.

It won't break with an automatic saver.

It usually doesn't have any effect.

As soon as the power is turned on, the computer will automatically turn on, usually there are two possibilities: 1. The motherboard or power supply quality is not good. If the power supply or motherboard is not of good quality, when the host is connected to the power supply, an instantaneous inrush current will be generated, which may make the power supply mistaken for a power signal, resulting in automatic power on as soon as the power is turned on.

2. The BIOS settings of the motherboard are incorrect. There is a "Power Management Setup" setting item in the motherboard BIOS, in which you can select the status of the computer when the power is re-powered after an unexpected power failure, which can be divided into auto-power-on, keep the shutdown state, maintain the state before the power off, and set the auto-boot to OFF. Plus, it's easy to solve this problem with Optimizer!

There are people who often encounter such problems! It's mainly a matter of CMOS settings! In fact, this can be said to be a common problem of ATX motherboards, because the ATX motherboard needs to detect the level signal of a capacitor, if it cannot be guaranteed to be good at one time when the power is turned on, it will produce an instantaneous inrush current, which may make the power supply mistaken for a boot signal, resulting in a mistaken boot.

In addition, if the capacitor is discharged quickly in a humid environment, the charging current will be impulsed at the moment of turning on the power supply, which may also lead to a false start-up. Because whether it is plugging in the power plug or pressing the power switch of the power strip, it is a process of energizing rather than instantaneous energizing, which is easy to make the state of energized unstable. You can try to connect the power supply directly to the switch with a pressure spring shrapnel, you can ensure that the contact is good in an instant, the energized state is stable, and the problem can be solved.

There are also motherboards that have a function in the BIOS, that is, Power Fail State or AC Loss State or PWRON After PW-Fail in Power Management Setup (Power Management Settings), etc., this function can choose the status of the machine when the power is re-powered after an unexpected power failure, whether it is automatically turned on or kept in the shutdown state or the state before the power is off, please set it to OFF.
