Hello guys,



I am having this problem from the time i had reinstalled the OS on my laptop,
I have an Acer 4920g. The media touch (ie, Play,Stop,Next,...) of my laptop is not working. I have installed the drivers which i got. Plz help me solve this problem.
Oh yes, and the empowering technology buttons and the acer arcade deluxe button does not work too,

Thanks
