The reason why the shutdown becomes heavy is 5 solutions for the shutdown and restarting.

Solution 1: The registry is modified [HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Window NT\\Currentversion\\Winlgon] and then the new name is changed or changed. The string value of "PowerdownAfterShutdown", whose value "1" indicates that the computer is powered off when it is powered off, and 0 indicates that it is restarted. Exit the Registry Editor and restart Windows for the changes to take effect.

Cause 2: Advanced power management is awkward. As we all know, shutdown is closely related to power management. The cause of shutdown failure is probably caused by poor power management. Solution 2: Click “ Start & Rarr; Settings & Rarr; Control Panel & Rarr; Performance & Maintenance & Rarr; Power Options & rdquo; In the pop-up window, enable or disable “ Advanced Power Support as needed. If you are using "Enable Advanced Power Support" when the failure occurs, try to cancel it. If the failure occurs, you are using the cancel "advanced power support" and try to enable it. Will be solved.

Cause 3: System settings are messing up

Windows XP defaults to automatically restart when there is an error in the system, so when the user shuts down, if the system fails during the shutdown process Restart your computer. Turning this feature off often resolves the failure of an automatic restart. Solution 3: Right click on the desktop and click “My Computer”, select “ldquo;” attribute in the pop-up menu, pop-up “System Properties” window, click ““Advanced” tab, click In the “Startup and Recovery” column, the “Settings” button pops up the “Startup and Recovery” window, as shown in Figure 1. In the “System Failure” column, remove the checkmark before the “Automatically restart” option, and click the “OK” button.

Cause 4: Virus destruction (this solution is not necessary, everyone knows)

Cause 5: The BIOS setting may be incorrectly modified by the BIOS regarding power management options. If you are familiar with the BIOS settings, please enter the BIOS and try to modify the BIOS related options for power management. If you are not familiar with the BIOS, then simply select the "Load default setup" option to restore the BIOS to the factory default settings. The most common cause of automatic restart after the computer is turned off is caused by a quick shutdown.

Workaround 5: 1 Start\\Run\\Input: msconfig\\OK\\System Utility Configuration Program\\Advanced\\Select“Disable Quick Shutdown\\Restart the computer. 2 If you still can't solve it, see if there is a driver or hardware error. The brain automatically restarts when it is normally shut down, usually due to problems with the power management of the motherboard. Some motherboard power management components are not very accurate in response to level signals due to wiring design and part quality. Since an instantaneous high voltage is generated at the moment when the main board is cut off, the high voltage has a short time and has little effect on hardware damage, but usually causes a small pulse to be generated by a PCI device such as a network card or a modem. If it is not determined to be a noise signal, and the automatic wake-up function is enabled in your motherboard BIOS, the motherboard will detect the external connection request of the network card and other devices, and then automatically boot. This reason is caused by hardware, so simply refreshing the motherboard BIOS can not solve the problem. You can try to turn off the automatic wake-up function in the motherboard BIOS, or you can use power management setup\\wake-up by pci card\\disabled.

The above is the solution to restart the computer, I hope everyone will gain something.
