hi @Anbby_ROG,i have already tried removing keyboard from device manager and updating driver. Windows 10 pro 22H2 is running on the pc, bios version is 308.

hi @Anbby_ROG, the keyboard is unstable  sometimes it works fine but usually it becomes unresponsive after turning on the laptop. in that case fixing takes several reboots by on/off button. also sometimes  random keys decide to work.before this one ...

Does anyone have the nk file for FX553VD or a similar model? I could not completely fix my keyboard with the files that I found online.
