Do not write letters with the letter Y.
Learn the ALT code for the letters  Y and  y.
   Y =089  y = 121
Program a key you never use to be Y.
Use the on screen keyboard.
Get another keyboard and plug it into the laptop.
   -- OR  --
Clean the keyboard. Of couse, if you are not very careful
you will damage it further.
