hi all.the dog trod on my daughters laptop earlier,and since then some of the keys don't seem to work properly,it's an advent,the keys affected have dual function, letters are in white, digits and symbols are in blue and are as follows, u/4 , i/5 , o/6 , p/- , j/1 , k/2 , l/3 , ;/+ , m/0 , when typing,the blue numbers and symbols appear instead of letters,if i type the letters,u i o p j k l m, they appear like this, 4 5 6 - 1 2 3 0.the same thing happens with caps lock on or off,for the keys to work normally,i have to hold a down a key in the bottom left corner with Fn written on it.this key is also in blue.thanks in advance.
