Standby & Hibernation works with some timings but not others

[Rich]

I have a fully updated XP Pro SP2 system that acts strangely when
going into standby & hibernate.

I can successfully put the system into either standby or hibernate
with Start, Turn off the Computer, Standby (or Shift for Hibernate).
And it returns correctly.

However with the Power Schemes timing settings one works and one
doesn't.

For the power scheme where the timing for turn off is:
Monitor=1 min, HD=3 min, Standby=1 min, Hibernation=2 min THIS WORKS

But for the power scheme where the timing for turn off is:
Monitor=5 min, HD=25 min, Standby=10 min, Hibernation=20 min THIS
FAILS

What appears to happen in the failing case above is that the monitor
shuts down, and the rest of the system remains powered up. The HDs
may be powered down, I can't tell over the case fan noise.

There are no errors in the event logs when this occurs. All drivers
are MS certified. There was a fix from MS for systems that have a Gb
of memory, but I have only 512Mb. I tried the hotfix anyway and I was
told that the hotfix was only for XP and I have XP SP2.

Any of you experts have a clue?

TIA, Rich

A copy/paste from your message below: "> But for the power scheme where the
timing for turn off is:

It seems to me that if the HD is going to shut down 5 minutes AFTER
Hibernation then it will NEVER go into Hibernation. Catch-22 kind of thing?

I thought that when hibernation is achieved, everything except the
monitoring circuitry on the MB was shut down, including the HDs after
the hibernation file is written to it.

In any event, the same timing relationship exists with the timing
group that does work. ie. Hibernation=20min, HD=25min
