Keypad light wont turn on

You have press the NumLk key (number lock) and this changes the right hand keys to a number pad.
Press the NumLk key (also doubles as the ScrLk key to toggle the Number lock). it is near the F12 function key. When the NumLk has been enabled a LED light is turn on to indicate this function has been selected. Press the NumLk key again to turn off the Number Lock.

Normally, if you hold down the "Fn" key, you'll get whatever character or function is printed in blue on those keys. So holding down the "Fn" key, you now have a numeric keypad in the middle of your keyboard. Release "Fn" and things are back to normal.
Which is exactly the opposite of what the question is asking. The person asking needed to press the "Fn" keys to get the normal, white, characters for each key.
The "problem" is simply that there is a persistent toggle. If you press "Num Lk" (I've also seen it labeled "Pad Lk" for numeric Pad) it turns on the blue keys, and inverts the meaning of the "Fn" key - it's a way to use that embedded numeric keypad without having to hold down the "Fn" key the entire time.

To fix it, just find and press the "Num Lk" or "Pad Lk" key again. (Note, sometimes these keys are themselves "Fn" keys, so you may, or may not, need to also hold down the "Fn" key to get the right function.) Often there is an indicator light associated with the setting.

check that your Fn key is not stuck, enabling other functions. Or that the fmode key (if you have one), is turned off when you are not using it.

Keypad light is turned on and off by sensing whether you are in light or in dark.
The phone turns off the keypad light when you are in sufficient light conditions.
