APM issue: computer reboots on Shutdown, locks up on Stand By

December 15, 2007

Computer reboots on Shutdown, locks up on Stand By

Am working through various KB articles troubleshooting an APM issue

with my Win2K computer. Two problems occur:

1. When it's powered down via Start/Shut Down..., Shut down, the

shutdown proceeds normally, Windows closes out and the power goes off,

but as soon as the fans stop spinning (~3-4 seconds after screen goes

black), the motherboard fires up again and reboots, back into Windows.

2. Standby mode: computer appears to go into standby mode successfully

(popup reports going into Standby, screen goes black, disks stop

spinning, and CPU fan shuts off. But then the CPU fan and disks fire

up again, the front-panel disk and power LEDs come on and remain lit,

the monitor remains black w/no power to it, and the system is locked

up/frozen and won't awaken from any keyboard or mouse action. The

front reset button doesn't work, but depressing the front-panel power

button for ~4 seconds shuts off the computer. The computer must be

rebooted to come back to life.

No error messages appear at any stage (eg, "System Cannot Go to

Standby Mode Because..." [kb/197477], or STOP 0x9F [kb/246243]).

Initial results of working through the KB articles have me questioning

whether APM got installed with this Win-2000 installation:

BIOS (AMIBIOS 08.00.09, 06/20/05):

It's APM-compatible. Am quite confident (though not 100% certain) that

APM was enabled in the BIOS when Win2000 was installed.

Computer Mgmt:

"NT Apm/Legacy Support" is not listed/present (System Tools, System

Info, Device Manager (View menu, Show hidden devices). (This indicates

APM support is not installed, per "Mobile Computing",

http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/prork/prdc_mcc_bptk.mspx?mfr=true.)

Power applet in Control Panel:

No APM tab is present in the Power Options Properties menu (only tabs

present are Power Schemes, Advanced, Hibernate, and UPS) (kb/242495).

System standby setting is present in the Power Schemes tab (this did

not appear after a fresh install of Win2K, but did show up after

installing the ~76 Windows updates, SPs, and Hotfixes).

Advanced tab setting used: Power button Powers Off computer when

pressed.

Start / Shut Down...

Standby is an option when shutting down (kb/266169).

Apmstat.exe:

When run (from either the Run module [apmstat -v], or from Explorer),

this Support Tool appears to open a cmd window but the window

immediately closes; no report or open window remains (kb/242495).

Power on/off and reset buttons on the computer's front panel function

correctly.

This restart issue has been present since installing W2K (ie, before

applying any updates other than SP4, which is slipstreamed into the

install disk). This same computer and hardware/peripherals worked fine

regarding shutdown/standby on a previous install W2K before it was put

in storage 3 years ago; am now trying to resuscitate it.

Would like to know for starters if is appears APM is in fact installed

in this Win2K implementation, so I can continue working through the KB

troubleshooting articles. If it's not, assuming APM was enabled in the

BIOS when Win2K was installed, are there any other reasons why it

didn't get installed (and can it be installed after the fact)?

Below are some specs and BIOS settings for this computer.

Have been through kb/237556; remain unclear why you pointed me there.

Device Manager reports my computer as an ACPI Uniprocessor PC. This

seems correct to me: it's recognizing ACPI, and it's a single-CPU

motherboard. Should the HAL be reporting a different value for this

computer?

I have the Hyperthreading for the Pentium IV disabled in the BIOS, as

I understand Win2K does not support it.

Re: APM issue: computer reboots on Shutdown, locks up on Stand By

Then it is sounding like hardware failure. It's nothing to do with the

operating system.

I'm a little clearer now on the ACPI /APM issue: since it appears I

have an ACPI-compliant computer (Device Mgr reports Computer as ACPI

Uniprocessor), I assume that that's why APM (a secondary choice)

appears to not be installed in my Win2K: no APM tab present in Power

Options menu, and running ampstat.exe produces nothing.

Can you advise on whether I should thus disable the APM settings in my

BIOS? The MB and AMIBIOS documentation is less than explanatory on

this issue.

BIOS Power tab settings:

==================

Suspend Mode - Auto [other options = S1, S3 only)

Repost Video on S3 Resume - N

ACPI 2.0 Support - Y

ACPI APIC Support - Enabled

BIOS to AML->ACPI Table - Enabled

APM Configuration:

==============

APM Power Mgmt - Enabled

Video Power Down Mode - Disabled

Hard Disk Power Down Mode - Disabled

Suspend Time Out - 60 min

Throttle Slow Clock - 50%

System Thermal - Enabled

Power Button Mode: On/Off

Restore on AC Power Loss - Power Off

Power on by: [-All Disabled]

-RTC

-External Modems

-PCI Devices

-PS2 Keyboard

-PS2 Mouse

Is this a laptop? The tool apmstat.exe was only intended for laptops IIRC.

Never mind about the apmstat.exe; I was trying anything that could

help diagnose why my computer restarts when it powers off. Can you

advise on the BIOS question above?

December 19, 2007

Re: APM issue: computer reboots on Shutdown, locks up on Stand By

You might look for a bios upgrade here.

Zeke7,

Have you tried the BIOS S1 suspend mode? Resolved this issue for me.

markn62: thanks, yes I did try it once, unsuccessfully, but not in

every combination with other settings, eg with APM disabled. I'll give

As noted in tmy original post (Other Hardware Specs), the BIOS is

upgraded to the latest version posted by the MB manufacturer.

My question is what are the specific power management BIOS settings an

ACPI Uniprocessor PC needs for Win2K to implement its standby and
