How to hibernate using VBScript?

[johngross]

I would very much like to be able to schedule a backup process
immediately before putting my system into hibernation (rather than on
full shutdown, which means it will take longer to boot up).

Having failed to find a backup package that will do this, I am
investigating using a script to do it for me. I have found a VBScript
"command" that was said to do the hibernate function I'm looking for,
as follows:

Set objshell = CreateObject("Wscript.Shell")
objshell.Run "rundll32.exe PowrProf.dll SetSuspend State Hibernate"

but when I run this script, I get an error box titled "RUNDLL" with
the text:

Error in PowrProf.dll
Missing entry:SetSuspendState

and, of course, nothing else happens.

Can anyone help me solve this problem?

Checking my previous post, I noticed an error. The second line of code
I quoted should read:

> objshell.Run "rundll32.exe PowrProf.dll SetSuspendState Hibernate"
