I am getting continues beep sound

I am getting continues beep sound when I turn on my laptop. It says press F2 or F12After pressing F2 or F12, Nothing happens. Any advice?

I think you are getting a beep sound (error) when you turn on the laptop because of a defective keyboard. Most likely a key or keys got stuck causing the laptop to make a beep error. You can try to disconnect the keyboard from the system board and turn on the laptop without the keyboard connected. If the laptop will boots fine, then the keyboard is your problem.
