Going from standby to hibernation

[Fred Byon]

Hi all,

Just wondering if anyone might be able to shed some light on this...on my
current motherboard, I am able to go from full power to one of the ACPI
power-down states with no problem, whether it be full power to standby or
full power to hibernation, but for some reason, I cannot have the computer
go from standby to hibernation, even though Windows XP supports it.
Whenever the computer tries to go from standby to hibernation, the machine
just comes back on and shows me the desktop. The XP error log makes no
mention of the machine's attempt to hibernate, so no help there.

I was able to get this to work on my previous motherboard (an Intel Socket
478). I'm guessing this is probably some kind of hardware issue, or perhaps
some motherboards have problems going from one power-down state to another.
All the drivers on my machine are updated as well as the BIOS, and the board
does support ACPI. Any responses would be appreciated.

Thanks,
Fred

It depends, I think, upon the sleep state you are in when Hibernate tries to
kick in.

If you are in sleep state 3 (drives down - fans off - power light blinking),
how can the drives spin - to write the RAM to the hibernate file? The
computer has to wake up to do this so the operating system has control of
the drive.

That sounds logicial, but when my machine goes to standby, it's S1, not S3.
I did try setting standby to S3 in my BIOS to see what would happen, but
that just turned the machine back on and NO DISPLAY on my monitor. I was
forced to reboot as a result. So, going from either S1 -> S4 (hibernate) or
S3 -> S4 doesn't work for me at this point.

You do have the timing adjusted correctly in your options - right!

Example:

Go to sleep in 20 minutes

Go to hibernate in 30 minutes - which is 30 minutes "after" the computer has
gone to sleep - (in my experience). Maybe you are just not waiting long
enough.

But then maybe it is just my computers that do this.
