A hinge for a notebook computer has an L-shaped first seat with a first opening and a second opening. A barrel is mounted on the first seat, and has a rib received in the first opening, and an ear received in the second opening. A pintle rotatably extends in the barrel and mounted on a second seat by a butt of the pintle inserted through a third opening of the second seat. The first seat is mounted on an LCD monitor of the notebook computer, and the second seat is mounted on a body of the notebook computer. The hinge has a simple structure and a low cost.
