1 BIOS turn on the motherboard ACPI function.

2Control Panel - > Power Management - > Advanced Options - > Power Management Advanced Power Management.

Reinstall the system Now your system's power management is AT power If it's an ATI power supply, you won't have this problem, or select "Control Panel" - Power Management - Advanced Options - Power Management, and then select "Enable Advanced Power Management Support", and then turn it off. If it still doesn't work, you can try the method of modifying the registry provided below.

Run the registry.

hkey_local_ machine\software\microsoft\ windows nt\currentversion\ winlogon。

Under this subkey, if the key value "powerdownaftershutdown" exists, change its value to "1", if it does not exist, add a new key value of type "reg sz" and set its value to "1".

Close the registry.

In addition, an ATX power supply and an upgrade file from the computer manufacturer are required. If you don't have this file, you can find a file called Windows NT Service Pack 4 that works on multiple systems. After installing this file, it is possible to automatically turn off the power without the upgrade file of the computer manufacturer.

To install, run the following command in the MS DOS environment:

-cd %systemroot%\system32

-rename

-copy g:\i386\

In this way, it may be possible that the computer will be able to shut down ...... automatically

Turning off the power directly is very harmful to the computer, the biggest is the hard disk, the hard disk is rotating at a speed of 7200 revolutions per minute, and the head is also working.

When you don't give any instructions, turn off the power directly, which will make the head directly scratch the platter of the hard disk, which becomes a physical bad sector, and there is no way to read and recover the files on the bad sector.

It is possible to corrupt files that have not yet been saved to disk.

Recently, some users have reported that the computer always pops up the prompt "Please do not turn off the computer, or unplug the power cord, the update is being installed" when the computer is turned on or off. In fact, this prompt is mainly due to the system turning on the windows update update function, the system needs to configure the system after installing the update patch, which needs to be performed at boot or shutdown, so it cannot be forced to shut down, otherwise it will cause the system to not work, but we can turn off the system update to cancel the prompt problem, the specific setting method is as follows:

Computer win7 power on and off always prompts "Please do not turn off the computer or unplug the power cord" Solution:

1. First open the win7 system start menu and select the "Control Panel" option in the list;

2. Modify the viewing method of the control panel to "Category", and then click the "System and Security" option;

3. Find "Windows Update" on the right side of the window and click it;

4. Click "Change Settings" on the left side of the window;

5. Under "Choose how to install updates on Windows", select "Never check for updates" in the drop-down menu of "Never check for updates (not recommended)", then uncheck the checkboxes in front of "Accept important updates in the same way as provide me with recommended updates" and "Allow all users to install updates on this computer", and finally click OK.

Although updating the system patch can improve the security and stability of the system, but in the update process will affect the system performance, after the installation of the update will also appear "please do not turn off the computer or unplug the power cord" prompt, we can follow the tutorial method to set the system never check the update, then there will be no such prompt in the power on, it is recommended that the user after a certain period of time in the installation of win7 update can protect the system security.

Unplug it, reinstall the system and go. Otherwise, even if you wait until the Year of the Monkey, you won't be able to make up for x

Under normal circumstances, the system can not be powered off when updating the patch, otherwise it may cause the system to crash and not be able to enter the system, although sometimes the update will be very slow, but this time is not a crash, this is not a crash, let it automatically update and shut down after completion, but if you can be sure that it has crashed, you can only force the shutdown and restart, as for whether it is a crash, you can press the light of the keypad to see if it can be turned on or off normally.

Look at whether the computer has crashed, continue to wait if it doesn't crash, and if it does, you can only restart.
