If you had APM or no power management activated, you will need to reinstall windows after turning on ACPI to load the new ACPI HAL and to detect the hardware again. Otherwise windows will be confused about the type of PC it's installed on.

It's possible that the BIOS setup has been accidentally set to non ACPI
mode. Check in the setup to ensure ACPI is enabled.Other possible
causes are memory expansion, overclocking and incompatible driver
software. Check out what you have recently installed or updated on your
computer.This can occur if Windows has detected that the BIOS in the
computer is not fully compliant with Advanced
Configuration and Power Interface (ACPI). To correct this problem,
contact the manufacturer of your computer to obtain a BIOS update that
is fully ACPI compliant. (If your PC is an older model, a BIOS update
may not be available). There are third party companies that will write a
BIOS update for your computer for a fee which may make it more cost
effective to replace your computer.You may also find help on this
Microsoft Support Site.
possible cause is that Windows XP was installed with the wrong power management hardware abstraction layer (HAL). Verify that power management is enabled in the BIOS. Open the Power Options applet from the Control Panel, click the APM tab, and turn on Enable Advanced Power Management support. If you don't see this option, the system is likely configured with the ACPI HAL and your problem lies elsewhere.
You can also reinstall Windows XP and manually select the ACPI HAL during installation to overcome potential power management issues with hardware (such as video cards) that does not support APM.
Enter you bios & disable ACPI. Restart the system. Than update your windows. There should be an update for ACPI through Microsoft update service. Once installed restart your system & enter into your bios. Now enable ACPI. Save & exit the bios.
If this does not help you can try the work around found on Microsoft's web site. See the link provided; http://support.microsoft.com/kb/314830
my client office one system working windows , when booting time displaying blue screen error" acpi.sys " . and then continusly system restart., but, i was maked the first and second repair, still now i didn't got solution for this problem. please help me. and also i want need ur help for blue screeen error.
if it does not help to upgrade the drivers Disable it in the device manager It also depends how new your current windows is This failure comes often when you upgrade your bios and running a old windows.
Hi martinkp, what you need is the update from windows. Leave you're acpi enabled withing the bios. Check windows update. Windows will update (windows software for the acpi). Rule of thumb concerning windows update. Check the dates of the updates & install in order, oldest to newest. This should fix you're system from shutting down. There will be no reason to turn off acpi after updating.
Look in your bios & see if you can disable the ACPI, (which you should be able too do. Finish installing your OS. Than update the OS. After completing all updates re-enter your bios & enable the ACPI. You should not get that error message after re-start.
Boards that support ACPI will get this error during a fresh install untill they get windows updated. All OS's
Post back if this did not help! It worked for me.
