We don't know if you have the exact issue because the original poster never cam back and clarified her situation. At this late date, it is doubtful s/he will be back. It sounds like you accidentally pressed the key that toggles your display to an external
monitor. Usually you need to press FN and one of the keys with a picture of a monitor although sometimes there is a different key toggle for presentation mode. Refer to your laptop manual for how to toggle presentation mode on/off on your computer.
