HiI have N5110 and a very weird problem when I type. Whenever I press the letter Z the laptop recognizes it and shows it like Y and vice versa. The problem is limited to these two letters only. At first it began in Word, now its applicable to the entire laptop. I checked language and input settings everything is in order. I don't know what to do, or how to reinstal the driver for the keyboard. please help!
Run a diagnostic on the keyboard (F12 at powerup). If the same thing happens when you try the keys, replace the keyboard.
