Windows 7: Monitor goes blank but stays on in energy saving mode

Monitor goes blank but stays on in energy saving mode

I recently did a clean install of Windows 7 Home Premium 64 after using RC 64 since this summer. Everything is working well, except instead of turning off when entering power saving mode, my monitor goes blank but stays backlit and the power light remains on. When the computer does then eventually enter full sleep mode, the monitor does turn off. Obviously not the end of the world, but an annoyance. Any ideas? My video card is the 5850 with the catalyst 10.1 drivers

I think the answer is that Windows 7 is checking or building your Hybernation file before it goes to sleep and the monitor/video card must think it is still running which it is.
When the Hybernation file is checked or whatever it dos itfinally goes to sleep.

Did I make any sense?
I personally turned my Hybernation mode off on my desktop. In my case it is just a waste of time and space.

Let me know what you think?

NOTE
I have turned mine totally off which speeded up my computer especially when I shut it down. I still can put it to sleep without an issue.
Here is the DOS command to turn it off.

Access CMD prompt using Run as Admin
powercfg -h off
Just cut and paste what I wrote above with the spaces


To turn it back on powercfg -h on
