I'm sorry, it's a Dell Inc. Inspiron 1440. I have a Fn key but not a Fn lock. I have a decrease brightness key, which is shared with F4, and an increase brightness key, that's shared with F5. I'm able to adjust the brightness of the screen with these two keys without involving the Fn key. This is strange to me, as the laptops that I've used in the past required the Fn key to be pressed in combination with a F key, or as you stated, a function lock for brightness adjustment.
