No S3 Sleep anymore after power outage.

Have you enabled the "Allow sleep when sharing media across a network" option in Vista advanced power management settings? Make sure the box is checked.
I don't think that sharing in that direction (i.e. your VMC accessing shares from another PC) would trigger a wake up event. When you recreated the the power profile, you did change the "when sharing media" setting to allow the computer to sleep?
I'm not trying to have a go at you, it's just that you haven't explicitly said that you tried everything that's been suggested. Wake on LAN in the BIOS for example - you said that you reset the BIOS, but you didn't say if you had disabled wake on LAN in the BIOS.
Why don't you unplug the network cable before putting the VMC to sleep & see if it still wakes? If it does, you can rule out any sort of weird wake on LAN or accessing shared media issue.
It's clearly an odd event, so I wouldn't rule out any mystery setting being enabled. Maybe the remote receiver is mistakenly sending a wake message?

Yes. When I installed my wireless keyboard I went in and disabled the relevent USB devices from waking up the system 'cause the keyboard is usually stored in a cupboard and sometimes gets bumped when people take stuff in and out, thus waking the system. So the only thing that was enabled to wake the system was the power switch and the remote.
After installing some Windows updates I used to get these mysterious occasions when I'd come into the lounge room and the machine was on, even though nothing was set to record. Turned out that the keyboard wireless dongle had somehow been re-enabled to wake the machine up. Disabled it again and all was good again.
You haven't loaded SP1 have you? Not intentionally maybe but does SP1 load if you have automatic install updates set?
My HTPC with Vista Home Premium was entereing sleep flawlessley, via the automatic settings, with the remote and by choosing sleep via the Menu's (in MCE and normal windows). Then I installed SP1. The PC would never enter sleep. The screen would power off but the PC, Fans and HDD would stay active. The only fix I could do was roll back SP1. S3 sleep now back to working properly.
I havent given up on SP1 just yet since I have noticed a new BIOS for my motherboard that mentions improved power options and I also think that some strange setting my be set when installing SP1, but if you installed SP1 either manually or automatically and are having S3 sleep problems I would roll back first and see if all is well.
Well, I stayed up until 2am last night trying to beat this problem.
to no avail.
I did a full re-install of Vista64 and the problem is still there (aaaaarrrggghhh!!)
One thing I have just discovered now is that the culprit is the PCI-e 1x slot that has my TV card in it. If I remove the TV card the PC will shut down, sleep, wake everything. As soon as I put the TV card back in.......no sleep, instant wake. It seems the card itself is stopping the PC from going into any sleep/hibernate state. Unfortunately there are no "options" I can set for the card or it's power use and the PC's motherboard has only 2 PCI-e slots (a 16x and a 1x) both are in use though so I can't swap them.
This is so weird because I know this system works and can use s3 without problems...it had done so since at least Nov'07.
I may have to try a different TV card in the system and see if that makes any difference.
Just found a "Fix" sort of. Very unorthodox but so far....it's working. Wouldn't really recommend doing it to other people though.
I took the TV card out of the system and rebooted. Then sent the system into S3 sleep, while it was in S3 sleep I put the TV card back into the PCI-e 1x slot. This made the PC wake up but since then it's gone to sleep and stayed asleep ever since. I've woken it up twice during the course of the day and it's gone back to sleep when I power off with the remote.
