hi, my "Fn" key does not work for some reason. it just stopped working 2 days ago. what should i do. i cant adjust the brightness of my computer!
Reboot the computer? Might want to clean the keyboard too - cookie crumbs and mechanics don't mix And of course you might have removed an important driver or a program that was responsible for handling the Fn signals.
I have a similar issue with a HP/Compaq NX6125 laptop. Function keys for brightness control don't work, but other function keys do. I guess it has something to do with display driver.
