Abstract

A hinge for a notebook computer has a base, a seat, a first ring, a second ring, a positioning ring and a fastener. The base has a hole and a flange. The flange protrudes from the hole. The seat is mounted pivotally in the hole and has a circular tab and a limit. The limit radially extends from the circular tab and selectively abuts the flange to limit the rotating angle of the seat. The first and second rings are mounted between the seat and the base to reduce the friction. The positioning ring is mounted in the hole and has a first boss and a second boss. The fastener is mounted in the hole and has a first notch and a second notch. The first notch and the second notch selectively engage with the second boss and the first boss to position the seat.
