True, but it shouldn't eat battery that fast.  This sounds similar to what 
happens on my system, turns out that the display isn't completely turned 
off, only the backlight is turned off, and if you look really carefully 
you can still see the video adapter is being powered.  From my 
understanding the video card display driver should handle this case, but I 
can't my card to work with any driver to issue these commands.
