If you are sill facing problem like brightness up and brightness down buttons not working then you might have to update you BIOS. To update your BIOS you have to download and install the Windows BIOS Flash Utility from the ASUS support site and also download the latest BIOS (See :How To Upgrade Your BIOS). Now just upgrade your BIOS, this would make your hot keys work definitely as far as i have tried it.
