When we use laptops, we may encounter situations where the laptop cannot be shut down. Many people are confused about this. What is the cause? What are the solutions? What are the methods to shut down the laptop? The editor will share them one by one with you below.

What is the reason why the laptop cannot be shut down? How to solve it?

1. Computer hardware Caused by.

The motherboard BIOS does not support ACPI very well. It is recommended to upgrade the motherboard BIOS, which usually solves the problem.

2. Caused by computer software.

Check the Bootlog.txt file. The records listed below may cause the computer to fail to shut down. You can find out the reason based on the situation displayed in Bootlog.txt in the root directory of the boot disk in your computer:

Terminate=Unload Network cannot be loaded. Network driver conflict

　Terminate=RIT Sound card or some old mouse driver and timer related issues

　Terminate=WIN32 Some 32-bit applications lock the system thread< /p>

　Terminate=Query Drivers There is a problem with the driver

　Terminate=Reset Display There is a problem with the graphics card settings or the display card driver

　3. Check [Advanced Power Management (APM) )]

Open [Start] | [Settings] | [Control Panel] | [System], and then click [Device Manager]. Expand [System Devices] | [Advanced Power Management], click the [Settings] option, and remove the check mark in front of [Force the use of APM]. If the computer can be shut down normally after restarting, the cause of the problem may be APM, and the advanced power management function should be turned off

Disable quick shutdown

Click [Start] | [Run] menu, Enter "msconfig" in the command box and click [OK]. The [System Configuration Utility] window will appear. Click the [General] page, then click the [Advanced] option. In the [Advanced Troubleshooting Settings] window that appears, select the check box in front of [Disable Quick Shutdown].. If the computer shuts down normally, there is something wrong with the quick shutdown item.

5. Check whether all applications have been closed when shutting down.

If not, you can close all applications. Because some application software may not be closed normally, and the system cannot end the application normally, resulting in malfunction

　6. When using IE browser, it takes up a lot of resources.

When you use IE 5 or higher to surf the Internet, please note that they still occupy a large amount of system resources after exiting, usually making the system's available resources less than 80%. After that, it will be very difficult to run other software. It is error-prone and may cause the system to fail to soft-shutdown.

7. When some software is finished, the system may not shut down normally due to the impact of certain operations on system data or files.

This situation is different from poor software design. This may be because the system itself is not good at protecting itself, and sometimes it is also related to multitasking. Although Windows XP has the feature of multitasking, some large software can easily cause malfunctions when multitasking is executed simultaneously, such as illegal operations, blue screen failures, and crashes. The problem of being unable to shut down caused by this situation usually does not occur the next time you turn on the computer.

8. BUGs in some programs or some 16-bit software may also damage system data or files in the memory.

Memory-resident software can also easily cause conflicts, resulting in abnormal system shutdown. It is not easy to find software with such problems. Select "Start"*"Programs"*"Accessories"*"System Tools"*"System Information" to open the "Microsoft System Information" dialog box and select "Tools"*" System Configuration Utility", you can set up to allow or disable multiple Windows XP-resident programs in "Startup". Other problematic application software can only find their shortcomings during long-term use in order to avoid errors in time.

How to shut down a laptop

1. The first method is to click on the lower left corner of the computer screen on, then offmachine. This is a normal shutdown, and all programs in the computer will run automatically.

2. The second method is to force a shutdown, which is to directly turn off the power of the computer. In this way, various programs will not be shut down normally, and the computer will automatically re-detect it when it is turned on next time.

3. The third method is to hold down Alt+F4 at the same time. At this time, a window to shut down the computer will appear, and then click Shut Down.

4. The fourth method is to hold down the Alt+Ctrl+Delete keys at the same time. A window like the Task Manager will appear, and then click Shut Down.

5. Enter shutdown-s-t 120 when starting the operation, so that the laptop will automatically shut down after 120 seconds. This is the method of automatic shutdown.

The above is the analysis of the reasons why the laptop cannot be shut down and the introduction of related methods. I wonder if you understand it? The editor is here It is not recommended to force a shutdown here. The computer will automatically re-detect it when it is turned on next time. This is not only a waste of time, but also not beneficial to the computer. I hope the above content will be helpful to you.
