Laptop won t turn off, laptop won t shut down why

1. The sound file is corrupted when exiting Windows.

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.

2. There are too many loaded programs.

You can run "msconfig" to turn off the program that starts automatically at startup.

3. Pay attention to "Advanced Power Management".

In addition, the Advanced Power Management (APM) feature on your computer can also cause shutdown, freeze, or black screen issues. To determine whether APM is causing the shutdown issue, you can open "Device Manager" and open "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.

4. Shutdown failure at start-up.

It is not uncommon for people to encounter failures such as "You can safely shut down your computer" when Windows is just started, or shut down immediately at startup or restart when it is shut down. The cause of such malfunction is generally due to or damage to the file. The workaround is to re-retrieve the two files from the Windows installer package.

Put it into the Windows System subdirectory, change the name to Make Backup, then open "System Tools", select "System Information" - "System File Checker" in "Tools", select "Extract a file from installation disk", and enter "Or". Repeat this step to replace the file or.

5. There may be problems.

Extract a file from the installation disk.

In addition, you can check for files or conflicts within them. Use the texter to inspect the contents of these two files to see if there are any redundant commands, or you can use "rem" to prohibit the execution of certain statements, and gradually eliminate them until you find conflicting commands.

6. Check the CMOS settings.

Incorrect CMOS settings will also cause computer shutdown problems, you can enter the CMOS settings page when the computer starts, 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 manual for specific settings, which have very detailed setting instructions, if you really don't understand the settings, it is recommended that you directly use the factory default settings.

Unplug the network cable, shut down, if it doesn't work, antivirus, shut down again, if it doesn't work, use your method to shut down and turn on again (I don't know if your restart function can be used?) ), enter safe mode, and shut down. If it is successful, you will go into safe mode to check for poisoning; If that fails, try restoring the system.

Just reinstall the system.
