The problem with my netbook is that the keyboard on the letters j,k,l, etc. have numbers included on them.  Something has happened

to where we cannot use all those letters on the right side of the keyboard (the ones that also have numbers on them) as all that

come up are the numbers.  I am not speaking of the line of numbers above the keyboard letters - I am speaking of the ones only

on the letters to the right of the keyboard.  Can anyone tell me what has happened and how I can fix it?

 

Thanks!
