OK, so I downloaded the latest nVidia WHQL driver, the one you linked me
to today ( 169.21_forceware_winxp_32bit_english_whql.exe ) and I was
about to do as you say above when I thought I'd continue what I was
doing earlier in the day before I took a break from all this -- I had
done a google on "standby greyed out" and got lots of hits. On the
second Google page was this one:

A guy suggested the fellow having the problem do an Everest Home Edition
report and paste it in a post. Having the program already installed, I
did a report and started searching through it for a clue. I left off at
around 25% into the long report. Just now, I decided to look further
into the report before uninstalling my display driver and installing the
new one. I noticed this about my rather newish 500 GB SATA HD:

[ SAMSUNG HD501LJ (S0MUJ1PP310938) ]

In particular, I noticed where it said:

Advanced Power Management Not Supported
....and...
Power-Up In Standby Not Supported

So, I figuring it was another wild goose chase (I've been doing them all
weekend trying to resolve this!), I went into the BIOS and disabled SATA
HD support. Upon rebooting, my 500 GB SATA drive is no longer seen, but
my Standby and Hibernate are suddenly ENABLED!

I find this amazing. SATA HD's are supposed to be an advance, a relative
newcomer in the PC storage scene, and installing one has disabled my
ACPI! I wonder if there is a workaround? Maybe if I get an SATA
controller card?? Or maybe if I get a different SATA HD?
