Great said:
Thanks, I'll try the former. We tried the latter, driver was dated 11/05, so
don't think it was updated, but there is a tab to "update driver" so I'll try
that first (once I close all programs).

Device Manager - "Computer" entry - Properties - Does the HAL
name mention "ACPI". For example, mine reads "ACPI Multiprocessor PC".
You want the word ACPI in the property.
On desktops, the BIOS has options like S1, S3, S1&S3. These are
ACPI states, and S3 is "suspend to RAM". S4 is Hibernate as far
as I know.
Download dumppo.exe (only 13KB or so) from Microsoft.
ftp://ftp.microsoft.com/Products/Oemtest/v1.1/WOSTest/Tools/Acpi/dumppo.exe
In a command window, change directory to where you've got
the dumppo.exe file, then type "dumppo cap". That displays
capabilities.
For example, my computer has working Standby and Hibernate. This
is part of my dumppo output.

System states supported.: S1 S3 S4 S5
Dumppo can also be used to do an administrative override, and
change what is supported. Users typically do this, if a BIOS
setting (the S1/S3 thing) was botched, and has now been corrected
in the BIOS. At that point, dumppo can be used to repair the OS,
so the OS recognizes standby/hibernate. Perhaps your IT guys already
know this, or have tried, and it still isn't working. Apparently
some of this stuff involves extensive registry changes, and isn't
something intended to be repaired by hand with a registry editor.
I mention the "ACPI" thing at the beginning of this post, because
occasionally someone installs an OS, and the BIOS has a small
problem with ACPI compatibility. The OS installer then does
a non-ACPI install and may have presented a dialog box, warning
of such. When it happened to me, I needed to update the BIOS,
so everything would work right.
Dumppo apparently has the ability to report a driver that
is preventing ACPI from working right, but I've never seen
that capability demonstrated.
