So, after having some problems with acer drivers for windows 8.1, i installed windows 7, and, what a big surprise, everything works, even touchpad, which has wrong drivers in acer site for windows 8.1, but for windows 7, touchpad driver works. Well, almost everything. There still is some work to do and some fog to be cleared. The problem is hotkeys - they work, but half of animations doesnt exist :
1) animations that exist : touchpad on/off, capslock on/off, wifi hotkey brings separate menu;
2) missing animations : screen brightness, volume up/down, volume mute.
I looked in acer launch manager files, and there is no more animation files, why ? Are acers wonderful artists still working on making those superior animations ? Or maybe acer just fired all their IT stuff ? Or maybe they are not so smart to know, that such thing also must be included ? Maybe i could help them ? But seriously, why are those animations missing ?
