I have been using Hibernate since December and it works perfectly. It also seems to add only a few seconds to the restore time, even on the odd occasion when sleep works as it should. Other times, with S3, it either crashes or hangs, presumably while devices timeout and are reset. And these hangs can last much much longer than the time hibernate adds.
Altogether not worth the hassle, although I will retry with W7 SP1.
Thanks for the info jong1.
My thinking at the moment is;-
1. Why does my home system (Badaxe+4650) work perfectly with S3?
2. Why does the system I'm trying to fix work perfectly with S3 if I swap out the ATI 5670 with an nVIDIA 8600.
3. I know my home system also had correct S3 operation with my old 8600GT.
4. Why is nobody else seeing exactly what I've seen on three different systems using the exact same card.
It's this thinking that makes me wonder if the problem I'm seeing COULD be isolated to a specific model or batch.
Guess the next step is to take the 5670 home and see what it does to my stable system.
As another aside, I just removed the 10.6 drivers (uninstall+ driver sweeper) and installed the V8.673 WHQL driver for Windows 7 32-bit Edition drivers from Sapphire's website (http://www.sapphiretech.com/presenta....aspx?psn=0006
). The problem remained but instead of a solid hang the system keeps trying to reset the display device every few seconds. It's still unresponsive to user input (although if I move the cursor it is reflected after the next display reset so the system isn't completely dead). This difference in behaviour makes me think it could be a driver issue but the lack of similar reports makes it impossible to tell. Whether it can or will be fixed is anyones guess.
Any further information anyone can provide would be gratefully received.
All the best,
