I read that entire post but still no luck. I even tried installing W7 in a separate partition an with the ATK for W7 I can not get it work either. In W8 keyboard lights do not work and (neither in W7) and P4G Hybrid is working but when I switch modes it is not displayed on screen which mode I am on. Also volume and screen brightness indicators are not the ROG on screen type, just a regular W8 bar. Touch pad on/off switch is working properly and shows its nice ROG on screen indicator.
(I just checked the keyboard connectors and they are all in place and correctly plgged in).
Maybe bios thing ? I have just had my laptop unbricked with a new bios chip and is running v223 of the bios.
I also noticed that when I install KBFilter, it does not ask me for a installation path or anything, it just asks if I want to install it and then asks me to reboot. Then when I go into Control Panel / Programs and Features it does not show in the list of installed software.
