Does the hibernation option still appear in the set of options available in the Start menu by clicking on the little arrow next to Shutdown in the bottom right corner?  If not then check the Windows help system for hibernation as it identifies a few examples
of issues that might inhibit hibernation.
Then run the power troubleshooter
http://windows.microsoft.com/en-US/windows7/Open-the-Power-troubleshooter
then run both the Maintenance & Performance troubleshooters at Control panel, Troubleshooting.
If the settings you put in are not shown correctly in the power plan advanced options then look at this one next
When you configure power options for the active power plan in Windows Vista or in Windows 7, the changes are not reflected in the Power Options item in Control Panel
If that does not help then run the System File Checker to fix any corrupt files in Win7

There is additional guidance on it in sfc.exe /scannow
Finally, check your hardware compatibility
http://www.microsoft.com/windows/compatibility/windows-7/en-gb/Default.aspx
and check the entries in Device manager for any warnings, then try to update drivers - particularly the video card driver as that accounts for many power management problems.
Best of luck,

Using Windows troubleshooter:

• Click on Search on Charm bar and type Troubleshooting. Click on the very first option.
