What should I do if my laptop won t turn off, why won t my laptop turn off?

Causes and solutions:

1. The first thing that should come to mind is viruses and Trojans, as the eternal enemy of the computer, naturally become the primary object of suspicion, there are many kinds of computer viruses, many of which cause some viruses to cause the computer to not shut down, if the computer can not be shut down due to such viruses, just check and kill these viruses, you can enter the safe mode through cold start to detect and kill viruses, the effect will be better.

2. In addition to viruses, damage to sound files may also lead to failure to shut down. When you shut down, you will hear the shutdown sound, this is the audio file configured by the Windows system itself, if this file is corrupted, we may not be able to perform normal shutdown operations.

3. If the sound causes the phone to be shut down, reinstall the sound file or cancel the sound of the shutdown. Here's how to do it: first we open the control panel, find the sound option (it may be different depending on the system), then click on Sound & Audio Devices, and then click on the Sound tab.

4. Then find the program event, find the "quit windows" event in the drop-down box, see if the sound file required for shutdown exists, if it does not exist, you can copy one into it, or set the shutdown sound to none (after testing, deleting the shutdown sound file under XP does not affect the shutdown operation, the system will automatically set it to none, and other operating systems are unknown).

5. In addition to the software, the virtual machine will also cause the situation that it cannot be shut down. If the virtual machine is turned on and the system cannot shut down, the system will prompt you, at this time, you only need to shut down the virtual machine and then perform the shutdown operation again.

1. It may be due to the power adapter of the notebook being damaged and unable to charge normally, or the current battery is dead, you can try to replace the power adapter and then fully charge the battery;

2. It is also possible that the memory slot in the notebook is not in good contact, resulting in a black screen that cannot be turned on; You first cut off the power supply, open the back cover of the computer, then take out the memory, use the eraser to align the gold finger part of the memory, wipe it back and forth a few times, blow the ash, and then plug it back, cover the back cover, and generally it can be turned on normally;

3. The memory of the notebook graphics card is soldered, which can only be repaired by after-sales personnel; It may also be that the boot circuit of the notebook motherboard is faulty, such as clock, reset, power supply, MOS tube, etc., which may cause failure to boot, black screen, and IO problems, which can only be sent to after-sales service or repair shop to repair the motherboard; With the continuous development of technology, we now have more and more tools at our disposal. The computer has become one of the tools that we use more frequently on a daily basis. Computers can generally be divided into desktop computers, laptops, and tablets.

Today I'm going to talk about laptops. When we use a laptop, it will not be able to turn off, why can't the laptop be turned off? What should be done to solve such a situation?

Why won't my laptop turn off? A variety of solutions are introduced.

1.When the laptop can't be shut down, if you use forced shutdown, it can't solve the problem, even if the problem is solved this time, but next time it may still be like this.

2.Generally speaking, the laptop cannot be turned off because of a virus intrusion in the middle of the laptop. This virus is a more destructive virus. Generally, the shutdown of the computer is affected by the system file registry.

3.When the sound file in the middle of the computer is damaged, the computer cannot be shut down.

4.Another possibility is that there is a problem with the advanced power management features on the computer, which is also the cause of the laptop shutdown failure.

5.If the laptop cannot be shut down normally due to an intrusion virus, we can do it in the antivirus software on the computer and fix it. Today's antivirus software is not only free, but also very powerful.

When we do this, the computer is usually back to normal.

6.If you are not sure if the computer is caused by the damage of the sound file, we can check whether the sound file is corrupted through the control panel. If it is corrupted, then we can help to restore the sound file by restoring the sound file in the backup.

The problem of the laptop not shutting down properly can also be solved.

Reasons why the computer won't shut down:

One of the reasons: computer poisoning.

Computer poisoning caused by computer can not shut down is the most common reason, because now there are more and more types of viruses, coupled with we usually do not pay attention to the detection or anti-virus of the computer, resulting in some viruses in the computer, resulting in the computer can not shut down normally.

Normally, we need to use antivirus software to carry out a comprehensive anti-virus on the computer, and then kill these viruses, and then enter the safe mode through cold boot, the effect will be better.

Reason 2: Corrupted sound file.

Sometimes the sound files in our computer are corrupted, which can also cause the computer to fail to shut down. Under normal circumstances, when we turn off the phone, we can hear the sound effect of the shutdown. In fact, this is an audio file configured by the computer windows system itself, so when our sound file is damaged to a certain extent, we will not be able to shut down normally.

If the sound file cannot be shut down normally due to corruption, we can reinstall the sound file or cancel the shutdown sound.

The specific method is,Open the control panel in the computer first,Then find the sound option,Click on the sound and audio device,Then select the sound tab,If there is no sound file,We can copy,Or set the shutdown sound to none,So that you can shut down normally。

Reason 3: The program is running.

Another common reason is that there is still some software running in the computer, which causes the computer to be unable to shut down normally, at this time, we can right-click to start fighting one zero, and then click on the task manager, you can click on some of the software that is running, and then select the end, at this time, when all the running software is closed, the computer can be shut down normally.

In addition to the reasons mentioned above, there is also the virtual machine of the computer that is turned on will also lead to the failure to shut down normally, of course, the computer will have a certain prompt at this time, at this time we need to turn off the virtual machine and then shut down again, and the computer can be shut down normally.

The reason why the computer cannot be shut down normally;

1.In most cases, it is a virus Trojan that causes the computer to fail to shut down normally, and the more typical virus is the kidnapping Trojan, which is a new type of highly destructive Trojan, which is different from the traditional virus, it is by kidnapping the system file registry to achieve boot startup, resulting in the computer shutdown button is missing.

The sound file is corrupted and the computer cannot be shut down.

Incorrect settings will cause the computer to fail to shut down properly.

4.The Advanced Power Management (APM) feature on your computer can also cause shutdown, freeze, or black screen issues.

The computer shutdown does not solve the problem:

One. The computer was damaged by a Trojan virus, and the registry information was maliciously altered. The solution is as follows:

Step 1: Enter the main interface and enter [Kill Trojan].

Step 2 After installation, click on "Kill Trojan" to use the full scan function.

Two. The following describes how to fix the problem caused by a user mistakenly modifying the computer shutdown configuration file.

1.Start "Run", enter "regedit" in the "Run" dialog box, click "OK" to find the following: hkey-local- machine software Microsoft Windows CurrentVersion Policies, click on the "System" folder, and then double-click the "ShutdownWithoutLogon" item on the right.

2., "Start" "Run", enter "Run" in the "Run" dialog box, and then click the "OK" button. In the Group Policy window, double-click Administrative Templates, Taskbar, and Start Menu, and then double-click the Remove and block access Shutdown command on the right.

In the Remove and Block Access to Shutdown Command Properties window, click the Settings tab, select Disabled, and then click the OK button.

Three. The first thing you can do is determine if the "Quit Windows" sound file is corrupted - open the "Control Panel", open "Sound" and cancel the "Quit Windows" sound. If Windows shuts down normally, the problem is caused by quitting the sound file, and you can fix this by restoring the sound file from a backup or by reinstalling the program that provided the sound file, or by defining "quit Windows" as silent.

Four. When you boot up the computer, you can enter the CMOS settings page, focusing on checking whether the CPU external frequency, power management, virus detection, IRQ interrupt opening and closing, disk boot sequence and other options are set correctly. You can refer to your motherboard's manual for specific settings, which has very detailed settings instructions, if you really don't know about its settings, it is recommended that you directly restore the factory default settings.

Five. To check if the Advanced Power Management (APM) feature can also cause the shutdown freeze or black screen issue, open the Device Manager and open the System Devices. In Advanced Power Management, remove the Enable Power Management selection.

If the computer shuts down gracefully, the cause of the problem may be APM. "

There are several reasons 1 may be systematic, such as poisoning (including Trojan horses).

2 It is possible that it is the cause of power management.

Can you tell us what type of computer you use, what system?

Win7 or Visita? visita slower shutdown...

Failure to shut down may be due to corrupted system files, and it is recommended to reinstall the system.

System reinstallation can be divided into ghost reinstallation, Microsoft system disc reinstallation, and software reinstallation, among which ghost reinstallation is the most convenient and simple, and is the most common method of reinstalling the system.

ghost reloaded.

Ghost reinstallation is the easiest and most convenient way to reinstall the system, almost all computer stores and repair shops and unofficial system discs are based on ghost reinstallation, ghost reinstallation has the advantages of easy operation, fast reinstallation speed, and simple method.

The ghost reinstall system is a gho image of the operating system from the Internet, and then use the ghost tool (generally use onekey ghost) to reinstall. These mirror system files are generally more than 600M, Win7 is generally about 3-4G, and Win8 is generally about 3-4G.

Reboot and reinstall. This is the most convenient way to reinstall the system, just restart the computer, no USB flash drive or install software, press and hold a button, you can reinstall the system. The specific steps are as follows.

Restart the computer, hold down shift when restarting, and when the prompt to reinstall the system pops up, you can put it in your hand, and you can operate it according to your needs (save the file and not save the file, the wrong point cannot be modified, please choose carefully).

USB flash drive reloaded. U disk system is currently a more convenient way to reinstall the system, only need to **U disk startup disk maker to make U disk startup disk, and then set up U disk startup when entering the system, the production tool can be online**.

Use the UltraISO file to write the system ISO to a USB flash drive.

On the BIOS interface, adjust the USB flash drive to the first boot item (you can also use the computer USB flash drive to boot the hotkey).

Insert the USB flash drive and restart the computer, it will automatically enter the installation interface of the installer, and follow the prompts to install.

Disc reload. The most common method of using the disc reload system is to directly use the disc to initiate the reinstallation option. First of all, we can set the CD-ROM boot in BIOS, or press the relevant shortcut key to enter the boot menu and select CD-ROM boot.

Hard disk installation. From the Internet**iso (Microsoft original version is recommended), then unzip to a non-system disk, and then run the program in it, select Advanced during installation, and select the drive letter. The rest of the work is fully automated, unattended.

If a genuine image is installed on a hard disk, the original system disk will not be formatted, but the original files will be moved to it""folder, but you can't go back to the original operating system (the original system does not integrate the driver, you need to back up the driver in advance, or ** driver installation software (such as driver wizard, 360 driver master) network card version. ）
