Default Re: HP 450 G5 - keyboard problem

The keyboard connector data lines go directly to the EC. You may want to test them one by one. Find schematics for a board with the same EC, keyboard lines are defined by EC hardware and pinout doesn't change between boards.

Another alternative would be something silly like Fn function being on by default.
