What should I do if my laptop suddenly loses power and my files are corrupted? The connoisseurs came

A sudden power failure will damage the hard drive, so the files will be unreadable! The battery on the motherboard is to power the CMOS chip, it does not affect the hard disk, the battery on the motherboard can generally last three to five years, if your computer's time often slows down, you have to change the battery!

It's normal, it's not normal, it's all illegal shutdown, and it's easy to lose files.

Because a sudden power failure can cause damage to your computer's hard drive, resulting in unreadable data!

No, unless there is a saturated power supply, problems like yours will continue, check if it is a problem with the power plug, it should not be the motherboard's battery.

1. The computer suddenly loses power, and the files that are still cached will be lost because they have not been stored in the disk and will stop executing due to the power off computer operation.

2. Now most applications in the system have an auto-save function, and some files can be automatically recovered by restarting the computer after a power failure, and prompt whether to reply. Some document software also has the ability to set how much time to save automatically, even if the power is suddenly lost, not all files will be lost.

Because the file is not saved.

Start --- run Enter cmd OK.

Open the command prompt and type chkdsk f enter.

You can fix the error.

If the data of the file is not damaged, you can use professional file recovery software to successfully recover the file; There are many file recovery software online, and some are free;

Please note about file recovery tips and how to successfully recover files.

The computer won't turn on the solution:

1.Check whether the monitor and the main unit cable and connector are connected;

2.If the external monitor sees that the system has started normally, then you can check whether the switch button above the keyboard for turning off the power supply when the display is closed is normal;

3.If the external monitor and the pop-up display power-off switch are all right, the display cannot be displayed, then it may be a system problem;

4.If you are unconditionally connected to an external monitor, please reboot it and pay attention to whether the display screen is black at the beginning of the system boot in the DOS boot state. If the screen is also black when the DOS boots, and there is no normal self-test sound, it is mostly a system failure;

The startup disk may be set up incorrectly. Solution: Modify the hard disk mode. Boot up, press F2, F10, F12 Delete (depending on the motherboard) to enter the BIOS, and set the first boot disk as a CD, floppy disk or U disk to a hard disk (harddisk);

6.HDD MBR error can be reset with DiskGenius;

7.Check whether the optical drive, USB flash drive, floppy disk, etc. are inserted, if so, you can take them out and try to turn them on;

8.Enter the BIOS, modify the hard disk mode, set different modes and try to restart to see if it can boot;

9.Press F8 to enter the mode, and select the latest correct configuration or normal startup.

10.If none of the above methods can be solved. For desktop computers, please disassemble the case, unplug the hard disk cable and reconnect it, and then see if it can be started; During the boot process, listen to and touch the hard disk with your hands to see if the rotation is normal;

11.The one-size-fits-all approach: reinstall the system.

If you don't need to repair it with a disc, you can only go to the startup item and select Safe Mode to boot. As long as the hard drive is not broken, it is good to shut down and restart it in safe mode.

This question has been asked by many people, and the answers to various sources are also different.

In fact, there are several reasons why the power failure damages the computer, one is that the instantaneous current pulse caused by the power failure will cause damage to all the Wang Hong's parts. The second is that the hard disk is suddenly broken and the head is not retracted in time, resulting in damage to the hard disk. These two problems will only appear ten years ago, the current power supply and motherboard have impact-resistant capacitors and diodes, simply power off that sleeps the impact of the book point will not damage the computer, and the current hard disk is intelligent ** head, once the power is off, the hard disk is intelligently detected, it will use its capacitance The remaining weak power in the land family will dock the head, so it will not damage the hard disk.

Although power-off will not damage the hardware, abnormal shutdown of the system will lead to the loss of unsaved data and corruption of data being read and written, so it is not recommended to use power-off to shut down.

Give a few points... So many words typed ...

Any piece of hardware can be damaged. But the first thing to bear the brunt of is the power supply.

If it is a good power supply, it will protect the internal combustion road, and the cultivation stove will protect the other hardware of the machine, and if it is damaged, it will only damage itself.

If it is a poor quality Piling power supply, it generally leads to hardware directly connected to the power supply, such as motherboards, hard disks, and optical drives.

The biggest impact on the hardware should be the hard drive, which can lead to hard drive failure and damage.

It also has a certain impact on the operating system, and abnormal shutdown may lead to the loss of system files.

In addition, when the computer is started after an abnormal shutdown. The system will generally give several options, such as "normal startup", "select the last correct configuration", etc., at this time, you can choose the last correct configuration, which will restore your system to the last configuration as much as possible and reduce the loss caused by unexpected power failure.

It's okay like you, after all, the battery is on the computer, and the lag is only due to the change of the power supply, so don't worry.

According to what you said in this case, there won't be much harm, because the computer is a little stuck when you play games with batteries, which proves that the game you are playing is a little power-hungry, so that when you use the battery's power, it will hurt the battery a little, but there is no big problem, generally the computer will be harmed by the sudden power failure without putting the battery, at this time the computer has no power at all, it will cause a little damage to the computer, the main damage is on the damage to the hard disk and memory, and the others are nothing.

No,,。 As long as you have power. Even if the power goes off, it won't hurt.

What is your battery, there is no battery, and it is the hard disk that suddenly loses power.
