My best advice is: Check all drivers for all hardware devices to ensure that they are the current best for Windows XP.Most Win XP shutdown problems reported thus far have been that it reboots when shutdown is attempted.
Currently, the leading cause of Windows XP shutdown problems is hardware incompatibility, including driver issues. However, it is impossible to list every possible hardware or driver issue individually.
See more questions like this: Why can't I lower my laptop screen's brightness It didn't work. Since the solution above did not work for you, the best way to deal with this issue is by contacting their customer support by going here: Home.aspx? If you do not see the Windows logo on your computer screen, most likely your Laptop is Windows 8 and has not yet been upgraded to Windows 8.1.
Normally, a Windows based operating system has their logo as a clickable option to go to your computer settings and do some changes and upgrade.
