ACPI not recognized by Windows XP, getting message "It is now safe to shutdown your computer"
Posted on 2010-01-08
I replaced a dead motherboard and reinstalled Windows XP Pro. I did not realize until I was all done that it does not shutdown correctly. It shuts down and then gives the message "It is now safe to shutdown your computer", kinda like it used to be with Windows 95. I checked my Power Management tab to enable ACPI, but the tab is missing. I checked device manager to see what it says under computer, and it shows "MPS Multiproccessor PC", instead of "ACPI multiproccessor PC". It would seem that Windows XP thinks that this is a non-ACPI compliant motherboard, even though it obviously is. So, I figured the next logical step would be to check over the bios. I started by loading defaults, but still same. I checked for a bios update, but already got the newest. I checked every setting for anything related to ACPI and changed it, but still same thing. I have a Gigabyte GA-EP45-UD34 V1.1 with a bios version of EP45-UD3R F11. What a dumb problem!! I hope someone can help me with this. Thanks in advanced
