please some of my keyboard keys are not correct. When i press L (3) is typed, it should be L
When i press shift/0 ( / ) is typed it should be )
Are you using a Laptop? Sounds like the NUMLOCK is on - this often maps the keypad keys to the right-hand part of the keyboard on laptops, meaning 3 comes up when you press L. Look for the key marked NUMLOCK, usually top right on your keyboard when you press it the numlock light should go off
