laptop display turn off on closing of the lid

[Guest]

In XP, within the power settings, when I set the options to "do nothing" when
the lid on my Inspiron 8600 is closed, the display would turn off but the
computer itself would still be running. With Vista, doing the same thing,
does not turn off the display, further more when the lid is closed other
power settings don't apply either. For instance, I set the time at which the
display turns off at 20 minutes, it does not turn off the display if the lid
is down.

Is this just a glitch, or do I have to do something else to achieve the
functionality I want?

I'm having the EXACT same problem. I would like to close my lid on my laptop
and have the display turn off but keep the computer running. It worked
flawlessly under XP and doesn't with Vista. This is a MAJOR issue with me.
