I have a asus g74sx, I reinstalled my os, becuase I had a virus. I think I have all most all of my drivers, all but one of my function keys are working. The one that is not working, is the battery/performace button, its the by the power button. The button changes the performace of the computer, like the brightness. Im I missing a driver or is there something wrong? I downloaded the ATKACPI driver and hotkey-related utilities driver. Is that the one? One other thing, is there a program that will update my drivers and install drivers that im missing?
