When a computer malfunctions or requires an emergency shutdown, many people worry that a forced shutdown will cause data loss. In order to solve this doubt, PHP editor Baicao will introduce in detail the impact of forced shutdown on data. This article will explore whether force shutdown can cause file corruption under different circumstances and how to avoid potential risks. Read on to learn how to safely handle a forced shutdown and avoid data loss.
Right-click My Computer-->Properties--->System Restore---->Tick before turning off System Restore on all drivers-- -Confirm. Exit and try again. In addition, this situation may also occur if you do not follow the correct shutdown procedure (forced power off).
1; If the disk is damaged, forced shutdown will undoubtedly be harmful to our computer. Disk damage is the greatest. Forced shutdown will cause the disk head to be unable to be reset. When you turn on the computer again, you need to search for tracks. For example, if we are writing a file, forced shutdown will cause file loss at best and hard disk damage at worst. It will have an impact on the system. Forced shutdown will cause system damage. Problems such as blue screens, black screens, error codes, etc. appear. If the above errors occur during forced shutdown, it is recommended to restore the system to ensure the normal operation of our computer. 3; resulting in data loss. Forced shutdown will cause the loss of part of the software currently running on our computer, such as ours. Office documents, and some other data programs.
It may also cause damage to the software and make it unusable4; forced shutdown of burned parts will cause various data conflicts, which will produce high-voltage arcs in the components inside the chassis, affecting some computer components and causing damage5; reduce the life of the hardware Forced shutdown skips the software and hardware restoration configuration operations when the computer is shut down, thus damaging the life of the hardware, such as computer motherboards, graphics cards, and other data-type components6; I personally recommend that forced shutdown will not cause damage to software that is not running, and occasionally Forced shutdown will not have much impact. In order to ensure the normal operation of our computer, it is recommended not to force shutdown unless it is absolutely necessary.
This is a forced shutdown of the computer. There are two types of forced shutdown of the computer: long pressing the power button and pulling out the socket, but the two types of harm to the computer are different, as follows:
1. Pulling out the socket (power outage) and forcing a shutdown has only a small amount of harm to the computer under normal circumstances. But sometimes it can also cause static electricity to breakdown the motherboard, the power supply in the chassis, or directly damage the CPU, reducing the service life.
2. Pressing and holding the power button too few times to force shutdown will not cause much harm to the computer, but frequent force shutdown may affect the computer system, causing the loss of system files and affecting the service life of the computer. So shutting it down once won't have any impact.
If there are documents on the desktop, of course they will not disappear, but if they are opened for editing and are not saved, then your edits will not be saved. content, unless the software has pre-saved edited content, then opening the software again will return to the editing state when the power was cut off. If there is a power outage and forced shutdown causes the system to be inaccessible, you can start the PE system through the USB flash drive and enter the C drive. Copy the file to the desktop path
It will cause some damage, but occasionally the damage will not be too great.
It is best not to have a sudden power outage when using the computer. Once in a while, it is not a big problem, but if it is done frequently, it will cause great damage to the hard disk and cause bad sectors on the hard disk that cannot be repaired. When the power is turned off, there is no harm to the hardware of the hard disk, because the hard disk consists of the disk body (four structures, including magnetic surface, track, cylinder and sector), and the read-write head assembly (read-write head, transmission arm, and transmission shaft). Part), head drive mechanism (voice coil motor, head drive trolley and anti-vibration mechanism), and spindle assembly (bearing and motor). It can be seen that the hard disk head drive uses a voice coil motor drive form, which is structurally This ensures that the magnetic head will automatically and quickly return to its position (return to the start-stop zone) at the moment of power outage.
When the computer is shut down, it always shows that it is logging out and cannot be shut down. You can follow the following methods to solve the problem:
1. First shut down the computer, that is, press the power button for about 8 seconds to force a shutdown
2. Such problems are caused by software conflicts, inappropriate drivers, or system problems. Can you restore the system or reinstall the operating system? Do not install software, patches, drivers, etc., and see if there is still a problem after shutting down? If you are not installing drivers, patches, and software step by step, don't install anything that is inappropriate. Note: If you press the power button to shut down the computer for a short period of time, although the computer will have a black screen, when you press the power button again to turn it on, the screen will still display "Logout"
If you press the power switch on the chassis, it is equivalent to a normal shutdown of "Start" - "Shutdown", because under the default settings of Windows, pressing this button is quite For safe shutdown, and the current computer power supply adopts ATX standard, so pressing the power button will not force a shutdown immediately. To force a shutdown, you must press and hold the button for 4 seconds (to deal with a crash). If it is an old machine and uses an AT standard power supply, the button is equivalent to an ordinary power switch. It turns off when pressed. It has the following destructive effects:
1. Damage to the hard disk. This is the most important thing, because it is forced to shut down suddenly. The hard disk head cannot be reset and will be searched again next time the computer is turned on. Repeated attempts may easily damage the hard disk;
2. Ongoing operations and unsaved data will be lost, sometimes causing the system to be abnormal;
3. It is easy to occur inside the chassis device. High voltage arc burns equipment. If you directly press the switch on the power socket or unplug the plug, it is also easy to damage the monitor. If it goes on regularly, it will damage the CMOS battery, and the life of the hard disk will also be reduced. It is less harmful than a sudden power outage, but it is very harmful. Sometimes It affects the shutdown process of Windows, making it impossible to shut down normally in the future. It is actually a misunderstanding that directly turning off the power will harm the machine. Someone has done experiments and found that as long as the hard disk is not working, there will be no harm if the power is turned off directly. In the past, it was said that directly turning off the power is harmful, but it actually refers to the hard disk. If the hard disk is reading When writing data, there is a sudden power outage or you press the POWER button to shut down. At this time, the hard disk head is very close to the platter and is running at high speed. It is easy for the head to hit the platter, causing damage to the hard disk and data loss. This is very scary. Consequences, so many people conclude that they cannot be shut down directly. In fact, current hard disk manufacturers have also adopted a lot of protection technologies to avoid this situation. Occasionally restarting after a power outage or crash will not cause much harm, as long as it is not in If the power is cut off when formatting the hard drive, hard drive partitioning, upgrading the motherboard BIOS, or using GHOST to restore the image, there won't be much of a problem. However, for the sake of safety, it is not recommended to turn off the power directly. It is better to shut down the computer according to the normal shutdown sequence! There are many things that can be damaged, but the most important thing is the hard disk. The hard disk dies very quickly, not only reducing the life of the hard disk, but also leaving wrong files under the system disk, causing the machine to run slowly or even incorrectly. Sometimes the wrong files are connected. It cannot be deleted even if you delete it, which will greatly affect the system. It may also burn the power supply or the motherboard. This happens randomly, because the current may increase instantly and burn the motherboard or other hardware. If you often do this, it will not last for several months. Do not break down the circuits of hard disk or CPU and other hardware. Abnormal shutdown can be said to be a hard disk killer. It is recommended not to use it all the time, or it is best not to use it
1. After the computer is forced to shut down and restart, it will automatically run the system file check program. If there is a problem with the system file or the hard disk has bad sectors, it will be automatically repaired.
2. If you cannot enter WINDOWS after restarting the computer after forced shutdown, there will be a selection menu in DOS. Select "Last Known Good Configuration" to solve the problem.
3. You can use the chkdsk tool to repair the damaged system disk. The chkdsk tool repairs the hard disk. Even if the repair is unsuccessful, it will not cause secondary damage to the hard disk files, which is safer.
4. If none of the above methods can solve the problem, you can restore the system backup or reinstall the system.
