Won't sleep!

[Gordon]

I've just built a new desktop computer, using a Gigabyte S-series
GA-P35-DS3L/S3L motherboard with an Intel Core 2 Duo processor,
two 1 MB memory sticks and a 500 GB WD hard drive. I am using an
ACER 22 inch flat-screen monitor. This computer works very well
and seems very stable, but it won't go to sleep. I have checked
and re-checked the BIOS settings, trying various changes. I've
right clicked on the desktop to bring up the Display Properties >
Screen Saver > Monitor Power window and tried every conceivable
setting here.

Windows XP Pro, SP 2

This computer will go into screen saver mode as the settings call
for, then after that times out and it should turn off the hard
disk and go on into sleep mode it comes back to a regular desktop
and just sits there...for hours.

I've switched the keyboard and mouse back and forth between the
new USP and the old PS/2 hardware, but this hasn't produced any
noticeable differences.

What else can I try or look for in the BIOS or Display
Properties?

Thanks for your insights on this. Gordon

Found the problem! I re-installed the drivers for the e-GeForce
7600 GS video card and the problem seems to be resolved.
Apparently something went wrong with the initial driver
installation, or they became corrupted later. Anyway, the sleep
mode seems to be working well, now.

There is a utility called "dumppo.exe" you can get from the Microsoft site.
It is only 13KB and runs in a command window.

ftp://ftp.microsoft.com/products/Oemtest/v1.1/WOSTest/Tools/Acpi/dumppo.exe

These are options for the program (listed on a French web site)

This is "dumppo ps cap" from my Win2K machine.

S3 is "Suspend To RAM" and is what gets used for Standby.
In S3, the fans go off, PCI cards are powered off (except for standby voltage on
the LAN card, for wake-on-lan), processor is powered off, RAM runs from +5VSB.
S3 allows the computer to restart rapidly when you wake it up.

The dumppo "admin override" option, allows changing the supported
states. If, during an install, the BIOS didn't do the right thing
when declaring ACPI states, you can use dumppo to repair the damage
after the BIOS settings have been fixed. Google for the following:

dumppo.exe admin /ac minsleep=s3

ACPI only works, if the "Computer" entry in Device Manager,
mentions ACPI in the name string. If it says "Standard Computer"
or something similar, you're in real trouble, and dumppo cannot
help. Dumppo is only useful if an ACPI HAL was used.
