[SOLVED] Hibernate missing after Win xp reinstall

Hi,

I just reinstalled Win XP Home SP2 and all the drivers for Inspiron 640M laptop.  After doing so, the Hibernate option disappeared when I click Start, click Turn off computer, and looking at the menu that pops up.  However, when I right click on any part of my desktop, and get the Display Properties message box, then click on Screen Saver Tab, then Power... to bring up another message box by the title of: Power Options Properties, and then go to the Hibernate Tab and click on Enable Hibernate, then I see the Hibernate option ONLY in the Power Options Properties message box under Power Schemes Tab, BUT not when I go to Start, then click Turn off Computer and the message box. 

 

I have restarted the computer a number of times since enabling Hibernate as above, but the Bibernate option fails to come up when I click Start, then click Turn off computer.  I used the Win XP reinstallation CD that Dell sent.  I also have Dell Quickset installed.  I installed all drivers correctly, including NSS, Chipset, Video etc.  Any ideas on how I can get the Hibernate back would be greatly appreciated.  Thank you.
