Win XP system shutdown Prompt "You can safely turn off the machine" What is it?

I recently installed a ghost version of the XP system, the result of the screen when the prompt "You can safely shut down" and then do not move, only the power switch can be turned off. And I've set up advanced power management support in System properties. It seems that the cause of shutdown is very likely to be the power management system support is not good, click the "start → settings → control Panel → Power Options", in the pop-up window, found no "Advanced Power support" option, After careful analysis, it is found that the management mode to reinstall the power supply has the following two simple solutions:

Method One:

Open Device Manager, select "Computer", if the following your computer appears as standard PC, that basically found the problem, right click on it, select "Update Driver", in the subsequent dialog box select "From the list specified location", and then select "Do not search, I want to select the driver to install, and then select the power type of your computer in the list, and then follow the prompts to install. If not, download the "Power Mode modification" software, select the fourth "ACPI multiprocessor PC" system will automatically install the appropriate driver, and then restart it.

Method Two:

Restart after typing "rundll32.exe setupapi,installhinfsection Acpipic_up_hal 131%windir%infhal.inf" in the Run input box. Using method one is recommended here because it offers extremely rich options and can be changed to Standard PC mode if the system is unstable as a result of modifications.
