Notebook computer does not shut down, there are many reasons cause this failure, the following are eight solution:

1. Computer hardware reasons.

Not well supported motherboard BIOS ACPI, the proposed upgrading the motherboard BIOS, generally can be resolved.

2. Computer software causes.

The records listed below may cause the computer to shutdown failure, you can start according to their own computer Bootlog.txt under the root directory shown in the case, find out the reasons:

Terminate = Unload Network can not load the network drivers of conflict

Terminate = RIT sound card or some of the old mouse driver and timer-related problems

Terminate = WIN32 some 32-bit applications locking up the system thread

Terminate = Query Drivers Driver problem

Terminate = Reset Display graphics card driver settings or display problems

3. Check Advanced Power Management (APM)

Open the start->set->Control Panel->System, then open Device Manager and Expand System Devices-Advanced Power Management, click "set" option, removed by force before using the APM method checkmark.Restart the computer if the normal shutdown, the cause of the problem may be that APM, Advanced Power Management function should be closed.

4. Disable Fast Shutdown

Starting->Operation menu, in the command box enter "msconfig" and click on OK, this time appeared"System Configuration Utility" window.Click"Order" Page, then click "Advanced" option appears at this time "advanced troubleshooting settings" window, choose "disable fast shutdown".If the computer shuts down properly, it shows it's a rapid shutdown problem.

5. Check if has closed all the applications when shut down.

If not close, you can close all applications.Because some applications may not properly shut down, and the system can not properly end the application, resulting in failure.

6. Using the IE browser, resource-intensive.

When you use IE 5 or later should pay attention to the Internet, they still occupied large amount of system resources following the withdrawal, often make the system less than 80% of the available resources, after which it is easy to run other software errors may cause the system to not soft shutdown.

7. Some software in the end will probably be doing some operations on the system data or file system and affect then cause the result of can't normal shutdown.

This is different from the poor design of the software, this may be the system of protection of their own disadvantage, sometimes with multi-task related.Although the Windows XP features multi task, but some large multi-task while a software implementation is prone to failure, such as illegal operation, such as blue screen failures and crashes.This situation can not be caused by the shutdown of the problem is usually not appear in the next boot up.

8. Some programs BUG or some 16-bit software may also undermine the memory of the system data or files.

Memory resident software can easily lead to conflict, resulting in abnormal system shutdown.Find out the problem with this software is not very easy, select the "Start" "program" "Annex" "System Tools" "System Information", open the "Microsoft System Information" dialog box, select "Tools" " System Configuration Utility "can be set to allow or prohibit the" start "in the presence of multiple Windows XP program.Other applications in question can only be used in a long process to find their shortcomings, so in a timely manner to avoid the error occurred.
