I just got a brand-new Acer Nitro V, this is the first time I've booted it up, and within the hour my keyboard stops working. I was using my external one hooked up with the USB and it wasn't working, so I tried typing with the laptop keyboard and it also wasn't working. I tried restarting it several times and shut it down and booting up it. By pressing buttons i found out that only the function keys are working, but now I'm locked out! And even the on-screen keyboard isn't working! They all work separately but aren't putting any letters down!
