How to change laptop screen brightness?

[Tim]

Dell Latitude CPi-A366XT. I want to dim the screen (a lot!) for use in dark rooms. The Dell website says to use the Fn and up / down arrow keys, but they don't do anything. I tried looking in the Display categories, but couldn't find anything there that seemed like it would work either.

How can I significantly dim / brighten the monitor? The LCD monitor attached to the laptop.

IF the Fn and up/down arrow keys did work, should I be holding the arrow keys down steadily or tapping them repeatedly? Neither way made any changes.

hold the FN key as you tap the down arrow key

Tried that. Many times. Didn't work.

if you've got an ati card, in the display->advanced: color tab you can change it. i dunno about other manufacturers tho

I have a Toshiba laptop, but I had to download and install some software from their support site. I am sure Dell is pretty much the same.

do you have a key that has a a sun with a arrow pointing up and another one that points down, above the normal set?

uselly is a different color too

This is my first post here; just wanted to say hello and thanks a thousand times over. I just spent 45 minutes trying to figure out how to control the screen brightness on a 2-yr-old notebook that my brother-in-law salvaged from his IT department, and I found my answer here in 5 seconds from a 4-yr-old post!
