In addition, when you press the start key and go to shut down options, hibernate is not an option and sleep is in a light grey colour and cannot be accessed. I have tried everything in power management as well as switched it on through VAIO program. It is not an option in the BIOS
I don't believe that the sleep/hibernate option is as important as it used to be since computers today start up pretty fast and there is less than a min. difference in the time. Can't imagine needing a computer to come on in under a min. to be that important. When I'm niot using my computer I just turn it off and it turns on to the desktop in 60sec or less.
I finally figured it out, I needed to reload the INTEL Graphics Media Accelerator, as soon as I did that the sleep option appeared, it also fixed another long term problem that I have been having with reading certificates - go figure!!
Thanks for all your help!!
