power off with ACPI compliant machine and Standard PC HAL

[itsnBrockport]

were trying to shutdown and poweroff a machine with ACPI compliance, Standard PC HAL (we need this). the APM tab doesnt show up and we've tried a number of things such as a registry setting (HKLM\Software\microsoft\windows nt\currentverson\winlogon\PowerDownAfterShutdown = "1")

i also tried installing a Microsoft suggested method of NT APM/Legacy Support but when looking in the device manager it doesnt seem to want to enable itself, after enabling it shows a yellow exclamation and still does not show an APM tab in power options. (microsoft article - 810903)

does anyone have some suggestions? this works on other harddrives with Win XP(in same machine) with same HAL and without an APM tab. All we wish for it to do is power itself off after shutting down. Thanx.

The standard ACPI complaint HAL would not need an APM tab, that is for non-ACPI compliant machines.

1. Check the manufacturer to see if there was a BIOS update;

2. You did not specify what happens with a shutdown instruction: nothing?, it restarts? something else?

3. I have had some success installing the new Win2k/XP service described and available for download here:

sorry.
it says "You may now power off your pc." no error messages.

BIOS is up to date.

already running uphclean.exe

This is what Jim Eshelman refers to as "powerdown" and not shutdown issues, and it can be difficult.

Does a Start, Run, shutdown -s -f

shutdown the machine? Please advise. As it can be a hanging application, and in some cases this issue can be adjusted.

Shutdown -s -f does not work and returns an error upon execution

shutdown -u reboots the computer (instead of shutting down and powering off)

i do not believe it is a problem with a hanging application. I believe it is because we are using the Standard PC HAL. There must be some way to work around this problem. Thanks for your help up to now.

We need to keep the Standard PC HAL. It is the only way we can get Windows XP to boot across 5 different machines. There must be some other way to make the PC's power off when shutting down.
