Dell inspiron 8200, Turning the screen off

[Charles]

How do I make the screen turn off?  Closing the lid used to suspend the 
laptop but leave the screen on.  I then applied the dell acpi patch 
mentioned here http://sandcat.nl/~stijn/freebsd/dell.php and it help on 
some things.  Now, when I use sysctl to set the lid state to NONE it no 
longer suspends when I close the screen.  But, it still keeps the screen 
on as I can see through the cracks.  I need to know if anyone knows how 
to get the screen to turn off.  Thanks
