Windows 7 can’t Sleep

Sleep not showing as an option in Windows 7?
Right-click ‘Comment Prompt’ and select ‘Run as administrator’
Use the command:
powercfg -energy
After which you can see the report by Opening “c:\windows\system32\energy-report.html” in a browser to see the results.
In my case it was a Device Driver called VgaSave, so if that is what is causing your issue see below:
First update the video driver
Next go into Device Manager and View -> show hidden devices
Scroll down and expand ‘Non-Plug And Play Drivers’ -> Uninstall VgaSave
Reboot
