Default Windows XP SP3 issues with Standby and coming out of Hibernation

Just wondering!!!
When I create a shortcut using [Standby: %windir%\System32\rundll32.exe
powrprof.dll,SetSuspendState Standby] it works like a charm, which suggest
the machine has the capability to suspend and go into a real Standby mode
with no fans turning and with the response to wake up on mouse movement or
keyboard activity. What I would like to know is how do I get my installed
Windows OS to respond the same way. I don't know what the triggers are that
signal the computer to go into Standby, was caused it to execute the string
it used to tuck its self in and go to sleep.
I was wondering if, it was possible to somehow bury this string in the
windows directory and link it to the triggering mechanism. Probably not real
clear so I will try it another way. If I am currently pointing and using my
mouse to execute the instructions included in the shortcut I created how do
I get the computer to execute this or a similar action to go into Standby.
I keep thinking if the computer was incapable of going to Standby noting
would put it in that mode, yet I can manually. How do I get it back into an
automated state is the question. It has done it in the pass. I think I might
be close to resolving this, with your help, for myself and many other
people. I think the thinking is correct, if you will, just not concluded.
There are enough WinXP users around, and I suspect will be for some time to
come, that this might be a worthwhile pursuit.


In the article here, there is a suggestion that the Power control
panel options can have an impact on how the system behaves. But I'm
not sure I like doing this.

To put the system in to Stand by :-

1] Make sure that the system is hibernation disabled.

The thing is, where are the commands for doing that stored ?
Are they in the registry ? Are they hard coded in a DLL somewhere ?
Are they a response based on checking a whole bunch of registry
values (like the ACPI hive) ? Who knows ?

A respondent in a thread like this one, claimed there were
somewhere around 200 registry entries for this stuff (ACPI
related). And even with all of that, the important bits of it,
might not even be in the registry.

As an example, if I scan the registry for "powrprof.dll", I don't
find it. Neither do I find "SetSuspendState" (in case the
powrprof.dll was implicit).

I was lucky to find the dumppo info, when I needed it...

Another thing I tried to research in the past, was what actually
shuts off the computer. Is it the OS ? Is it the BIOS ? I think
it's some BIOS code that presses the button, but I've not been
able to confirm that.
