Recently my laptop keyboard stopped working. I'm now using Logitech wireless keyboard and configured it with a receiver via Solaar.
My laptop Keyboard was working before, I actually have no idea why it stopped working.
Kindly give some suggestion or solutions regarding this problem.
EDIT: Wireless Logitech keyboard and mouse are working just fine, but my laptop keyboard is not responding. When I type on it, keys got lighten up so it recognize the action but it has 0 effect in GUI.
EDIT2: I tried to reinstall my system now, wirelss keyboard is working from very beginning while notebook keyboard is not working - Solaar is not installed
EDIT3: Grub file:
linux /boot/vmlinuz-4.2.0-42-generic.efi.signed root=UUID=9d551829-77be-4690-8097-0bd9b6adce29 acpi=force acpi_osi=! ro quiet splash $vt_handoff
