I used CMD Run as Administrator > powercfg.exe /hibernate on or powercfg /hibernate on
This did not work.
I found Enable hibernation on Windows and downloaded Microsoft Fix it 50462
How to disable and re-enable hibernation on a computer that is running Windows
This did not work.
I searched all of Windows 7 folder for the file hiberfil.sys File Not Found
I run Windows XP Pro (sp3), Vista (sp1), Windows 7 Pro and Hibernation Works. Not with Windows 7 Home Premium and if I put Home Premium in sleep mode and bring out of sleep, I am not connected to the Internet (Cable Modem) which as far as I can tell, Network & Sharing does not have an option to Repair Connection, as does XP. Vista or 7 Pro / 7 Home Premium has Troubleshoot Problems running Windows Network Diagnostics does not find a problem.
I can place Windows 7 Pro into Hibernation or Sleep Mode and wake up just fine. The same of Vista and XP Pro.
However, 7 Premium out of Sleep Mode does not re-connect to the Internet. I have to re-boot.
Any suggestions are appreciated....Doc
