Thank you Dek. I have added a note under METHOD ONE to help let people know this quicker. :)
Hibernate - Enable or Disable

This sounds similar to Vista. With Vista however hibernation doesn't work with 6GB of memory (not sure where exactly the cut-off is). To be honest it's the biggest Vista problem I know of. I pre-ordered Windows 7 hoping hibernating is possible with any memory size. Sleeping works fine on vista but I'd much rather be able to turn of the power altogether. Not sure how laptop owners manage with Vista.
Anyway, could you please update the tutorial with a note regarding memory limitations, present or gone since Vista? Thanks very much!

Hello NocturnalOne, and welcome to Vista Forums.
Not sure if that may be a issue for everyone. I have 8GB installed without any problems with sleep or hibernation in Vista and Windows 7. You might check your BIOS settings to see if you have a "Memory Mapping" option to enable to see if that may help.Last edited by Brink; 27 Aug 2009 at 12:44.

Thanks Brink for responding so quickly. I only got Vista a few months ago when I built a new system with a Core-i7 and 6GB of RAM. XP Pro/Home before that. I enabled hibernation on my system using instructions similar (same?) as yours here. The hiberfil file was created and the system 'pretended' to hibernate but could not boot from the created file. Doing some googling found lots of references to a memory limitation in Vista related to hibernation. Examples:
Vista Machines with More than 4 GB of RAM Have Limited Shut-Down Options - Losing Hibernate - Softpedia
Which refers to this:
You cannot put a computer that has more than 4 GB of memory into hibernation in Windows XP, in Windows Server 2003, in Windows Vista, or in Windows Server 2008
Sleep works fine on my Vista machine but as soon as the power is disconnected it'd toast. I have no idea how your machine with 8GB works properly when MS says it shouldn't work. It's typically the other way around (they say it should work but it doesn't :)
Anyway, I sure hope Win7 resolves this absurd issue. I'll gladly allocate a few GB of disk space to be able to completely power down my machine at night, even if recovering from hibernation takes a bit longer than recovering from sleep (which is fast except that it typically forgets to load the keyboard driver for a minute or so after it comes up).
I should add that I haven't dared to install Vista SP2 yet, still at SP1. Misadventures with installing SP3 on XP have made me a bit nervous about messing with a generally stable system.

This problem is also sometimes fixed by a BIOS update. You might check to see if your motherboard as a newer BIOS version available and if the readme files for it address this issue.

What's the difference between 'Sleep' and 'Hibernate'?

Hello Seven,
Sleep - The computer saves the current session to memory (RAM) and goes to a low power state. If you lose power while in sleep, you will lose the current session. When you move the mouse or press a key on the keyboard, the computer will wake back up almost immediately.
Hibernate - The computer saves the current session to the hiberfil.sys file on the hard drive instead of memory, and goes to a near turned off state (less power used than in Sleep mode). It will take the computer a few seconds to save everything to the HDD before entering hibernation, and it takes a bit longer to resume from hibernation as well when you wake the computer up from the mouse or keyboard. However, if you should lose power, you will not lose the current session.
Hope this helps,
Shawn

Yes, that helps a lot!
I shall now disable Hibernate as I don't use it.
Thanks
