Try opening and closing it again, just to make sure. If it is not sitting exactly right, the sensor may not be actuating.
If that doesn't help, open the lid and look for the cover set sensor. It will most likely be a small black sensor with two rectangular tower-looking sides, and a plastic actuator on the lid will fit right into the space in between the sides when the lid is closed. Blow some compressed air onto the sensor to get rid of any dirt or debris that may have accumulated there.
