Probably a BIOS or video driver problem I would think.  Try using the Fn-F8 
combination (it is that on my 5150) to switch between CRT and LCD, this may 
manage to do something.

Also have a look at the display at an oblique angle to external lighting... 
its possible the LCD is up but the backlight is off.  In this case you can 
just see the image on the LCD if you get it at the right angle.

I have the nVidia card for my Inspiron and it has its own issues, the recent 
nVidia binary drivers stop sending data to the LCD panel if you enter one of 
the text consoles after being in X.  So don't feel bad about choosing ATI :-)
