Answer 1

Answer:

You can try by switching off the computer

Answer 2

This is called the backlit keyboard. This usually happens when we press F9 , F5 or F11 or dual keys like Fn + F5. On Mac we have to press the little rising sun to turn it on. If you want this to turn of press the same button you pressed to turn it on.

Hope this helps.
