How do I get better control over screen brightness

I bought a Dell Inspiron (which runs Windows 7) and they seem to have done something to the brightness controls because it seems to be more coarse than I remember from my previous HP Pavilion (EDIT: yep. I can only change the brightness in jumps of 6). I wish to get a better control of the screen brightness to tune it to the specific sweet spot I'm interested in.

The model is N5110. Is there a program or setting that can do this for me?

Solution 1:

If it is a Inspiron 1564 or similar chassis there is nothing you can do about it. If not try from the advanced power settings for the profile you are using.

Solution 2:

I also have an Inspiron. If you go to the control panel, then hit "Mobility Center", it can be changed more precisely there. Alternatively you can hit Windows Key + X to open this.
