Last night, my Asus Q550LF laptop was updated by Windows 10. When the update finished, it required a restart. Instead of waiting for it to restart when inactive (or later), I manually restarted my system. When Windows 10 completed bootup, my keyboard and touchpad did not work. I tried restarting the system, but no change. I even tried interrupting the bootup process, but nothing. I finally used the online keyboard with the touchscreen and was able to login. In the device manager, it shows a yellow exclamation mark for the keyboard and touchpad. I tried to update the driver, but no help. I uninstalled the driver to try and let windows discover and install, but no change. Any idea what happened? I refuse to believe my keyboard AND touchpad died at the exact same time. Thanks for your help!
