Windows 7: my pc doesn't sleep anymore.

Thanks, tried the new settings, but no go. I already have automatic updates, so I should have the latest drivers. Interesting, but some screen shots that I see on this forum do not appear on my Win7 Premium Home Edition ( ie, download drivers immediately and power management of mouse from device manager), and obviously SI and S2. Is there a reason for this? It seems a solution is just a matter of the stars lining up right on a particular day, but never guaranteed-how unacceptable and disappointing!

Did you confirm the BIOS version updated checking the version number on first screen or in BIOS setup? You can also read it using Belarc Advisor

According to Dell, it is the latest. A word of warning Belarc Advisor, Avast caught some trojans in it as have some other users in CNET's comment section.

Thanks for the heads up. We have another case where formerly trusted CNET has added a crapware package to a download which previously didn't have it. They have ruined their sites's reputation over this.

Have changed link to Belarc's own page for downloading Belarc Advisor

won't sleep issue finally solved

After many attemps at fixes-and much time-I can say that my sleep mode now works on my Dell. There was an unknown silent audio streaming that prevented sleep, no matter what I tried.
To find out if some program is interrupting sleep go to comand prompt as administrator (rightclick) and type in:
POWERCFG.EXE -REQUESTS; this will show program; and override it with: "powercfg -requestsoverride DRIVER xxxx System whre xxx is the program. For a more detailed analysis type: powercfg -energy -output %USERPROFILE%\Desktop\Energy_Report.html (which will icon on desktop). There will some "false" positives, but you will see the most likely culprit.
I actually solved the problem by updating the latest codec driver which fixed the streaming (and not using the overrride).
