I have a desktop computer with Windows XP Professional Service Pack 3. But my computer doesn't turn off properly. I didn't change any setting on BİOS or power options off Windows XP. When I turn off computer by click Shutdown icon, only case leds and display properly turn off but all the rest continues to work. Otherwise I want to add one detail about this problem. This problem often perform at my computer. So not everytime... Approximately %70 And if the computer doesn't turn off properly, I turn of the computer by press power button. But I don't want it. And I want to learn why it doesn't turn off properly. I have been waiting comments. Thank you...
it is recommended to switch off at the mains, this way you save energy. monitors and cpus consume energy during idle. in a way it solves the problem too.
Thanks for reply but I want to add one detail. This event does not always perform but it oftens perform. So I don't know what I do.
Assuming you're using an ATX power supply, most common cause of this is installing windows onto a machine where the ACPI power off settings were turned off. Windows has to be installed after power ACPI features are turned on in the BIOS. Look thru BIOS carefully, make sure ACPI is enabled before installing windows. If you have a much older AT power supply, then this is normal behavior. One other possibility is feeding 5 volts backward thru the USB ports with an externally powered USB device left plugged into a computer after the computer is powered off with some motherboards. Unplug or power off any external powered USB devices before shutting down windows.
İf the BİOS update unsuccesful, I have bigger problem than this. Otherwise all downloadable BİOS updates are BETA.
Yeah, ACPI is enabled before installing Windows. Otherwise before this event not perform, same USB devices plugged my computer. So USB devices isn't cause of this problem.
