i just did a clean vista install on my latop. but now the fn key on my keyboard wont work. when i go into device manager under keyboard it says standard ps/2 keyboard so that is installed. is this the correct one, i have been on the medion website but cant see driver for keyboard on this model of laptop. the rest of the keyboard works fine just fn key. im running vista 32bit and the laptop is medion md 96630, please help.
