I started to notice that my “w” key sometimes works but sometimes it “cuts off” and then works again. I notice this in FPS games as it feels like im running into a wall.
very likely general wear. replacing the keyboard fixes this issue regularily. however, a cleaning of the board may get it running. toothbrush and 99% alcohal can do the trick. if it doesnt work, replace the board. (i have the same issue with my space bar.)
