That would be because it isn't part of the user's interface to ACPI. How are
you _getting_ to S3? It isn't ACPI that tries to put the computer to sleep in
the first place, though you can have set up acpid (which isn't at all the same
thing) to do it. ACPI merely generates or responds to events - some external
process has to write to /proc/acpi/sleep to put it into S3.
You could disable sleep states in ACPI, but it requires rewriting the DSDT table
in the BIOS. The DSDT essentially tells ACPI what hardware options are
supported.
It sounds to me much more likely that your computer has _never_ gone to S3 but
that your BIOS might be attempting to do something outside of ACPI. What
evidence do you have? If I really thought this was an ACPI issue, I'd suggest
that acpi-support@lists.sourceforge.net would be a more appropriate place to ask
:-)
