After updating the drivers of my PC with the program DriverPack Solution, the keyboard on my PC stopped working. Touchpad is still functioning. I plugged a USB keyboard to keep working too. Is there any keyboard driver for the AN515-51 or any solution to this problem?

    Windows Defender Security Center detects a problems with the driver ELAN EzTouchFilter. I don't know if ths problem is related.

    Keyboard power button is working, hence, I can turn on or off the laptop from that key. Keyboard light turns on, but never turns off. It should turns off after 30 seconds of inactivity (if I'm correct.). I think ELAN EzTouchFilter probably is a driver for an external touch monitor that I have.

    I did a rollback on the driver ELAN EzTouchFilter, and I think that basically Windows remove it because the driver is no longer there. After that, the keyboard start to work perfectly. Still don't know exactly the purpose of that driver in Windows, but apparently it was directly involve with the keyboard problem.

    The keyboard will always turn off 30 seconds after the last key stroke. The timer is fixed at 30 seconds.
