If the laptop is currently attached to an external monitor, or TV set, it's not uncommon for laptops to sort of 'forget' that they have an attached LCD display. Try unplugging the attached monitor or TV and try again.
\015\012Other times, it's simply a matter of pressing the correct key combination, usually a special BLUE command key plus another key with the inscription LCD/TV on it, also in blue.
\015\012If none of these is your case, then I would expect that your laptop may beep to make you aware of the fact that the display is not working. Please look up in your user's manual for a symptom similar to yours and a possible cure to the problem.
\015\012If all else fails, contact the notebook manufacturer, or go to its support page on the web, and check the FAQ (Frequently Asked Questions) first before asking for paid help.
\015\012Good luck!
