I checked my machine's BIOS and there's no mention of APM in it, just ACPI. I also checked in my Device Manager and only ACPI is mentioned. There's no APM tab in my Power Management in Control Panel. I need APM so my machine can shut itself down properly, as it did under 98 SE. I read that XP cannot do this unless APM is installed and enabled.

So how do I get APM support for my machine?

Read over this link, its makes it as clear as microsoft can:

ok, basically, if you have a newer compuer you have ACPI installed automatically and you do not get an APM tab. APM tabs only show up on older machines where ACPI is not auto-detected, mostly P1's, some P2's.

So, if you having shut down problems, its not because of apm. Perhaps if you described your shutdown problem, we could try to help

OK my mainboard is a FIC AD11 with an Award BIOS ABA46. I updated the BIOS before I installed XP. My shutdown problem is, it gets to the part where it's safe to shut the machine down. I hear a soft click like it's trying to soft-power off, but then it just sits there. It used to shut down fine under the old BIOS which was ABA43 and Win98. So I aint sure if the BIOS or XP is to blame. I do have ACPI enabled in both the BIOS and Windows.

This is a similar problem to yours:

http://www.chron.com/cs/CDA/story.hts/tech/weekly/1439314

"Configuring Advanced Power Management
Windows XP Professional supports Advanced Power Management (APM), which helps reduce the power consumption of your system. To configure your computer to use APM, use the Power Options Properties dialog box. Click the APM tab and select the Enable Advanced Power Management Support check box. If the APM tab is unavailable, your computer is compliant with Advanced Configuration and Power Interface (ACPI), which automatically enables Advanced Power Management Support and disables the APM tab. You must be logged on as a member of the Administrators group to configure APM.
If your computer does not have an APM BIOS installed, Windows XP Professional does not install APM, so there will not be an APM tab in the Power Options Properties dialog box. However, your computer can still function as an ACPI computer if it has an ACPI-based BIOS, which takes over system configuration and power management from the Plug and Play BIOS."

Ah, I get this occasionally - the soft click (for me) is the hard disks shutting off, but the main power remains on. Used to drive me nuts, too! I would revert the BIOS back one revision and see if that helps; also try resetting the BIOS values to defaults and see if it works.

Good luck :)
