Lost Hibernate / Standby buttons on Shutdown Window

I have a Dell Inspiron 6400 running Windows XP Pro SP2. It is updated
regularly.
The hibernate and standby buttons on the shutdown window have greyed out.
I've updated the video driver. This didn't work.
How do I find out what has caused the problem?
How do I fix it?

I just noticed several PC's in our area also have the same problem.
