Brightness slider suddenly gone

#1
Hi, I have a toshiba satellite a350-13d laptop with windows 7 32 bit installed on it. All of a sudden, my brightness slider is gone, while it was there before when I clicked the battery in the bottom right corner and chose "change screen brightness" or something alike (I have the Dutch version of windows)

I didn't install anything in the meantime... Anyone else had this problem and how can I solve this? What driver is responsible for that slider?

Check your Windows Update history to verify if any new drivers have been installed lately.
Start>>"Windows Update">>View Installed Updates (or View Update History, I don't remember).
