Dell Inspiron thinks it’s a Latitude?

I’m trying to fix a Dell Inspiron 600m laptop whose screen keeps dimming. Before I diagnosed it as the backlight I wanted to update the FlashBios.

I downloaded the one from Dell for the Inspiron 600m and lo and behold when I go to run it a popup screen tells me that the current running Bios is Dell Latitude D600 and I therefore the Inspiron 600m bios will not install!

Any ideas where to go from here?
