I reinstalled Windows on my 4830TG yesterday and today I've tried to install all drivers. Everything is ok, only Launch Manager doesn't work. When I press fn+f3,fn+f5,fn+f6 and fn+f7 nothing is happening. I cannot enable/disable Wifi/BT, disable touchpad and turn off screen. I've tried to install original Launch manager from recovery cd and from Acer download site too and other versions - all have the same problem...
Buttons to control volume (fn+up/down), brigthness and mute works.
