My computer restarts when I try to shut down. I have read all the posts on this problem and thought I found the fix. NOT! I went into device manager and clicked on "show hidden devices" but the NT ATM / Legacy Interface mode was not there. The fix from tweakxp.com says to enable this but it is not there.

Any ideas? I have winxp pro, the one from the Microsoft Hot Deal for like 39 bucks.
Here are the specs.

MSI KT3 Ultra-2
AMD XP 1700
512 MB Crucial PC2100 DDR (2.X256)
Quantum Fireball 40Gb 7200 RPM 8Mb
ATI 9000 64Mb TV-out
Cendyne 32x12.40 CD/RW (Mitsumi 8Mb buffer)
Generic 48x CD-ROM
Evercase 4252
Sparkle 300w ps

Maybe you know already, but...

A lot of times, this happens because XP, by default, reboots upon system failure. Thus, a system failure upon shutdown looks like a reboot and hides any useful error messages. You can change that in My Computer --> Properties --> Advanced --> Startup and Recovery Settings.

Perhaps that will give you some hints.

Did you just install the OS or did this problem just arise?

The reason I am asking is that I just ran into a similar problem not too long ago. I was installing xp pro on the kids machine and I did a bios update before the install. I went and set bios defalts or something like that after the flash. Well I didn't go and actually check any settings and proceeded with the install of windows. Windows wouldn't shut the computer down I was getting it is safe to turn off computer.

Any how if you have just installed the os go into your bios and check your power management settings. If you have had the the os installed for a while and this just started happening chances are this is not the problem.

I got the same problem as you when I was playing around with ACPI, in the BIOS, and APM in the control panel.
When APM was checked, enabled, my computer would reboot when I asked it to shutdown.

Anyway try different combos with the ACPI and APM enable/disable's.

Good luck

This is an new machine with a fresh install of xp.

The problem I am having is, there is not APM tab in the power management window in control panel nor is there an NT ATM/Legacy interface to enable in the device manager. Yes I did click on show hidden items.

Any suggestions?

You will have to go into the bios and enable the acpi.

You will also have to reinstall windows. It requires a reinstall to enable the power management.

ACPI is enabled in the BIOS and is default, so it should have been enabled when windows was loaded initially.
As far as the windows re-install, can I just run setup again or do I have to partition and format the drive again and lose all data?
Any other ideas?

Check something real quick. Open device manager look under computer does it say standard pc? If it says ACPI pc you don't need to reload windows your problem is elsewhere. If it does say standard pc you will need to reload windows.

Yes it says "ACPI Uniprocessor PC".
What troubles me is the missing APM tab in the power management window in control panel and the missing NT ATM/legacy interface in device manager. Does anyone know why these are missing? I'm running out of ideas. I have tried about every combination of settings in the bios.

Are you talking about the thingy to set up power schemes?

if so, go to Display properties => Screen Saver => power.. => advanced

(sorry if this is not what you are talking about)

Yeah that is the window I am talking about. I get the impression that there is supposed to be a APM tab there. Look at pc_freak's post.
The only tabs I see are: Power Schemes | Advanced | Hibernate | UPS Do you have the same tabs?

I found this when I searched on "Advanced Power Management" in the help and support tool.

Windows XP and Advanced Power Management (APM) Support
The information in this article applies to:
Microsoft Windows XP Home Edition
Microsoft Windows XP Professional

Summary
This article describes how Windows XP installs Advanced Power Management (APM) support.
More Information
Windows XP supports the following two methods of power management:
Advanced Configuration and Power Interface (ACPI)
Advanced Power Management (APM)
ACPI is the preferred method for controlling power management. When ACPI support is not installed, Windows XP installs APM when any of the following situations occur:
The computer appears in the Auto-Enable APM list section of the Biosinfo.inf file. The computer passed APM tests and should work with APM. The APM tab is present and enabled in the Power Options tool in Control Panel.
The computer appears in the Disable APM list section of the Biosinfo.inf file. The computer is tested and found to have problems with APM. The APM tab is not present in the Power Options tool in Control Panel.
The computer does not appear in either of the lists, and is considered neutral. The computer is not tested for APM support in Windows XP. The APM tab is present in the Power Options tool in Control Panel, but it is not enabled by default. To configure this option:
In Control Panel, double-click Power Options.
On the APM tab, click Enable Advanced Power Management Support.
Microsoft does not recommend enabling APM support on a computer that is not detected as APM 1.2-compliant. If you experience problems after enabling APM support, disable APM, and contact the manufacturer for an updated BIOS. If a computer is a multiprocessor system, Windows XP does not install APM support.

If this doesn't help, at least it might lead you in the right direction.

The major thing I noticed is that APM is NOT the prefered method of power management by WindowsXP and is not installed if you are ACPI compliant.

Thanks Insidious, SemperFi and others!
I have not yet discovered the cause of the shutdown/restart problem but you guys have helped me exhaust many possible causes.
I have determined that the problem is not related to an error at shutdown.
I have tried to disable ACPI in the bios but comp won't boot.
I have tried myriad combinations of power management settings in control panel along with every combination of power management settings in the bios.
Google has stopped presenting me with new avenues of inquiry and it appears I may be about to exhaust you ATers as well.

Thanks SemperFi for comparing tabs with me, that helps alot. And Insidious, good info, I apreciate it.

Now what about the NT ATM / Legacy Interface mode icon in the device manager. Does everyone have it, or is it similar to the APM tab in the control panel (only there if windows installs APM or deems computer not ACPI compliant)? If I can determine the status of this bit, I can pursue other possibilities.

Thanks again

One thing about it you don't want to turn off acpi. I unknowingly had it disabled on an install of xp recently and when I did a shut down I got the screen It is now safe to turn off your computer.

So I had to go back to the bios and enable it and reinstall xp.

When you said you disabled acpi what did you mean it wouldn't boot? Did windows try to load and just seemly get stuck?

If you mean that windows just didn't finish loading. I would say that this is normal. The drivers for an acpi pc is different than what are used for standard pc. I remember reading in the os forum a year of two ago that on win 2000 it was possible to switch from acpi to standard pc. I don't know if it will work for xp. I don't know if you will find it. I don't know how long the forum preserves the threads. You might also use "HAL" in your searches. this was a common term used in the win 2000 threads pertaining to this.

Good point SemperFi, I used the wrong terminology. The computer did "boot", however windows would not load completely. I have searched the windows knowledge base to no avail. I have tried everything I can think of. I am nearly to the point of a repartition/format and fresh install of windows. I know it is drastic but I am out of ideas.

First of all, it's "APM Legacy Device", not "ATM". Second, APM == Advanced Power Management. A combination of BIOS and Windows control over power-management features. ACPI == Advanced Configuration and Power Management Interface. It is newer, and allows Windows full control over power-management features, so it doesn't have to coordinate with the BIOS to deal with power-management. ACPI is newer, and theoretically better, although it can cause interrupt issues because when Windows is running in that mode, all PCI INTRs are shared on a single IRQ, usually.

So therefore, if ACPI is present and enabled in the BIOS, and Windows was installed with ACPI, then there is no need to show/use the APM Device.
