    Was this upgraded with a full or upgrade Win8.1 install media? Can you still access the bios at the Acer logo screen? Does any of your other HIDs work, like the mouse, touchpad, etc? Does an external USB keyboard work?

    Have you tried uninstalling and re-booting to see if Windows will correctly re-install? Was the Win8.1 installation package a full or upgrade version?

    Try uninstalling the keyboard driver from Device Manager. Then re-boot and see if Win8.1 will correctly re-install the keyboard driver. If that doesn't work, then see if Win8.1 will autosearch for a driver.
