Windows XP designed not to power off computers?

[falcon2000]

Strange about that AMP tab. On this comp. I am using now ACPI is enabled in both the BIOS and Windows but there is no APM tab!

However, it does NOT have the shutdown probelm. It powers off all the way.

Anyone knows why I don't have the APM tab????

That's just exactly how mine is except it doesn't power down all the way. What's the difference? Please don't tell me it's my Logitech drivers. I ask again, how a mouse can interfere with a computer powering down. It's just a mouse.

Do you have a Logitech MX 700 mouse?

When I got my P4 2.8 GHZ with Hyper-Threading Technology, the mouse cursor would freeze up every time I start the computer. I found that my Logitech MX 700 mouse was the cause of It. I found on the Dell forums that every one that had a P4 with Hyper-Threading Technology needed to plug the mouse Into a USB port to solve the problem.

Your AMD may have a problem with your mouse or other hardware.

No it's just an old Trackman Marble Wheel. It's in the USB port.

Re the APM tab appearing or not in control panel, see here. ACPI will be used over APM if it is available.

From the MS link given earlier:

This behavior may occur if one or more of the following conditions are true:
Your computer supports the Advanced Power Management (APM) feature, but the Advanced Configuration and Power Interface (ACP)-compliant basic input/output system (BIOS) is not configured correctly to permit the operating system to turn off the power supply.
During an upgrade of the operating system, Windows does not detect that the computer is ACPI-compliant.
An OEM device driver or service is installed on your computer that is preventing the computer from correctly shutting down.
Your computer is not ACPI-compliant.

from my own experiences.. Motherboard drivers can cause these sort of problems.. certainly if the bios is not complient with the implementation of the XP ACPI.. check if there is a BIOS update for the MoBo, as well check that the latest drivers are installed for the mobo..

If you did a UpGrade install to XP. I recall an issue on the MS knowledge base that had a common cause of the upgrade.. can't find the link just yet .. (personaly i prefer clean installs.. to many probs with upgrade)

Or have you by chance upgraded the mobo/CPU?

.. it is funny.. I had a similar problem with RH7.1.. same machine.. Win98 or Me.. fine.. BIOS....re-flashed..RH now fine..

I have the latest BIOS. I flashed before wiping the HD and installing XP. The only driver for the mainboard I needed was the AGP slot driver for the Via SB.

Agh! I actually got it to power itself off after XP shuts down. But now I've moved everything over to a new case with a new power supply unit, and now it won't power down again. I have no idea what to do...

This has worked on a couple of machines I've seen:

"First get into device manager, then Go up and hit "view" then "show hidden devices". Now on the right look for "NT Apm/Legacy support". Under that should be "NT Apm/Legacy Interface Node". Enable that if it isn't."

Most machines don't have "NT Apm/Legacy support" so if it's not there, this isn't your problem.

*sighs* Not there. I've been through my Device Manager and CMOS with a fine tooth comb.
