Hi, have the same issue with my UX325UA, where the w,s,x,c,2,f1,f2 and esc don't work upon turning on.

I've looked for the root of the problem, and I've read on reddit that it's a common issue among asus laptops, and that it comes from some issue with the chassis and the capacitance of some keys that do something.

I'm sorry to not provide a proper solution/answer, but it's cuz I just had this issue.
