Toshiba Laptop Function Key Drivers

I have a Toshiba Satellite Laptop, model# M35-S320

I installed Vista (32bit) and my function keys do not work any longer. I do not have a recovery disc and I cannot find the drivers anywhere.

The function keys control the screen brightness, which I cannot use anymore. My screen is not bright enough and there is no way for me to raise the brightness without the use of the function keys.

Does anyone have any suggestions???

Thanks,
Super!

Click the link below. The drivers are for the Toshiba M35-S320 Satellite laptop and are provided directly from Toshiba. I used the Display Driver with Windows Vista (32bit, service pack 2) and it worked fine. Once installed, I was able to adjust my screen brightness manually from the Power Plan menu. The power plan menu is accessible via the Plug/Battery icon on the far right of the toolbar > more power options > change plan settings > adjust display brightness (slider).
