This worked for me.

anyway--"minsleep" is.
The "best" way to go about using STR is to enable "Suspend To RAM" in the
BIOS before installing the operating system. Unfortunately, this isn't common
knowledge, and no one (i.e. Asus) goes out of their way to TELL you this. I
didn't know myself, back in January when I built my A7N8X Deluxe system.
The good news is that DUMPPO.EXE can correct the matter--without having to
be run at every boot. Here's how:
1) Download DUMPPO.EXE from Microsoft (to ensure you get the correct file):
ftp://ftp.microsoft.com/products/Oem...cpi/dumppo.exe
2) Go to a command line rooted in the directory DUMPPO.EXE resides in, and
enter this command:
DUMPPO.EXE admin
DUMPPO.EXE will list some basic information about the current sleep
policies. For example, here is what I had before correcting matters using
DUMPPO.EXE:
C:\Downloads>DUMPPO.EXE admin
Admin policy overrides
Min sleep state......: S1
Max sleep state......: S4 - hibernate
Min video timeout....: 0
Max video timeout....: -1
Min spindown timeout.: 0
Max spindown timeout.: -1
The problem here is the "Min sleep state" value. When you tell WinXP to
enter standby mode, WinXP uses the "Min sleep state" setting to determine
what ACPI standby mode to use. In the case above, WinXP sees and uses S1
(which is normal standby, where all that happens is that the hard drive(s)
and monitor(s) power down).
3) Correct the "Min sleep state" value using the following command line:
DUMPPO.EXE admin /ac minsleep=s3
4) Reboot, and when you do, go into the BIOS and ensure that the "Suspend To
RAM" value is enabled(!).
5) Back in Windows, issue the DUMPPO.EXE admin command again, exactly as in
step (2), and you should see something similar to this:
C:\Downloads>DUMPPO.EXE admin
Admin policy overrides
Min sleep state......: S3
Max sleep state......: S4 - hibernate
Min video timeout....: 0
Max video timeout....: -1
Min spindown timeout.: 0
Max spindown timeout.: -1
The "Min sleep state" value should stay at S3, across reboots, and your
system should be able to enter STR mode. (Incidentally, when I ran
DUMPPO.EXE, I tried half-heartedly to monitor the registry and file system
for the changes it made, but came up with nothing.)
If your system enters STR (i.e. S3) mode properly, but does not restore
itself properly (e.g. the monitor stays blank, you get BSOD errors, etc.),
the most likely culprit is a buggy or incompatible driver or piece of
hardware.
I figured it was worth resurrecting this old thread in order to try to
help...
