Machine won't hibernate?

Hi, I installed the Win 7 Beta last weekend and so far I really like it. I just have a few minor issues.
The main issue is that my Sony Vaio Laptop won't shutdown; restart is no problem, but when I try to turn the computer off the shut down screen just runs and runs. I haven't even gotten around to messing with any of the power settings yet.

The only other aggravating issue is that McAfee won't work with Win 7 yet. I'm using a 14 Day trial of Norton for now, but I would really just like to use a free AV until McAfee delivers a working product. Does anyone have a suggestion? I've heard that Spyware Doctor or Avast might do the trick.

My Specs are:
Sony VAIO VGN-CR590E
2.4 GHz Intel Core2 Duo
3GB RAM
Previous OS was Vista Home Premium

I had the same problem and I think it was the USB selective suspend setting in Advanced Power options that needed to be disabled to stop it waking instantly after Sleep was activated.

Didn't work

Thanks for this tip, I disabled the USB Selective suspend and I can now shut down my system.

Hello!
I have similar problem, so I won't create another thread.
Everything was OK this morning, but when I try to hibernate my machine now it kind of "pops" out back. The screen goes black for a second and then lights up again showing my desktop. When I reboot machine and try to hibernate it remains black for 10 secs or something; after first try it wakes up almost instantly. Something gets cached?..
Like I said, this mailfunction appeared few hours ago. All I have done today is videodriver installation. The fact is I've already used this system (from the same installation disk) with the same drivers, programs, settings etc. So, I think, the problem is configuration, not the software itself. I have reinstalled my OS few days ago (before that I used it for 2 months) and I encounter such a problem first time.
I have followed your instructions from "How to Troubleshoot a Vista Sleep Mode Problem and Find a Solution" tutorial (thanks, great article), but it didn't help.
Can you advise me something else?
Sorry for such a long text, I just want to describe situation to get my hibernation capability back. I love this mode very much, I'm so upset I can't use it

P.S. I had watched through events written to system log after I tried to hibernate. Nothing relevant.
And one more thing: powercfg lastwake command shows me count of 0, like it didn't even began to hibernate...

P.P.S. Sorry for my poor English.
Thanks for spending time to read.

When I press sleep it goes black and after a few seconds shows the login screen.

Same problem as mine. Can you please post your solution here for me if you'll find it elsewhere?

So this is my 1st post on this site, I joined because I am out of ideas and I can not find a solution. The problem is similar but not exact.

When choosing the hibernation option the laptop will start to go what appears to be hibernation, but if I move the mouse or touch a key it pops right back up like it was just in sleep mode.

Any ideas I have been looking on and off for 2 weeks and I am getting sick of looking
