Sorry to bump a really old thread but I have some questions about sleep mode. I've been trying to get my computer to use S3 sleep state, but have been unsuccessful.
Whenever I try to wake my desktop from S3 Sleep mode, it will boot up as if it was shut down completely. It then displays the boot option to Start Windows Normally or in Safe mode, etc.
My BIOS is enabled for S3 sleep, and I tried using the registry option two in this tutorial, but it hasn't worked. The command prompt option using the command "powercfg -h on" only displays the following error:
Hibernation failed with the following error: the request is not supported.
The following items are preventing hibernation on this system.
The system could not create the hibernation file. The specific error code is 0xc000007f
I also wanted to ask about the administrator option to "Change settings that are currently unavailable". My user name is the only account on this computer, but I have never seen that option to view different settings.
