Inspiron 11" 3162 numbers not working unless holding caplock ?

I just opened a new Dell Inspiron 11" 3162, and I must have accidentaly hit the FN key or a function key that reversed my Caps, and also I am not able to type a number unless I hold down the cap lock key ?

Also my cap lock is inverted- caps type when light is off, and continue in caps only?Please help as it messes up passwords & other.

TYIA !
