Notebook Power Management

This is my first notebook PC, an HP Pavilion with Vista Home Premium, and
I'm trying to figure out the quirks of power management as related to sleep
& hibernate.

In the advanced power settings, one setting says (for example) to sleep
after 30 minutes and another says hibernate after 90 minutes. I understand
the difference between sleep & hibernate, but my questions are these:

1) This means that after 30 minutes of no activity, it will go into sleep
mode. So then after another 60 minutes, is it supposed to automatically
"wake up" and go into hibernate mode? This does not seem to be happening.

2) If I put it into sleep mode by closing the cover, should it transition to
hibernate after the 90-minute period?

My theory is that it keeps waking up from sleep mode due to scheduled
events, and that's keeping it from going into hibernate.

I also have seen that there are ways that the notebook can wake up from
sleep mode. In fact, I think it's hard to keep it from doing this since
there's always some software that wants to check for updates over the
network or whatever. But is there a way that it can be awakened when it is
hibernating?

Hibernate is pretty much the same as powered off except for the memory
contents being saved to disk. As far as I know, the only thing that can then
wake it up would be the BIOS, but I don't see any settings in the BIOS that
might allow this (I know that the network interface can do this for systems
that are remote-booted from a server). But I swear that I put the notebook
into hibernate the other night and yesterday I went in and it was just in
the sleep state!

Thanks, Bob. This is exactly what I was looking for. I haven't used the
notebook for a few days, but have been observing it. It definitely goes
from sleep -> hibernate -> wake -> sleep -> hibernate, but not all that
frequently. I'll try to track it down when I get a chance.
Unfortunately, my BIOS has no power-management options that are
accessible to me (unless there's a hidden way to see them). I think that
HP gets tired of helping people who screw up their BIOS settings!

You're welcome.
Did you press the F2 or Delete key as soon as your computer starts booting
to enter the BIOS?
