A hinge for a portable computer having a monitor with a pivotal end and a main frame with a pivotal end has a sleeve, a washer and a pivotal rod. The sleeve is mounted in the pivotal end of the main frame and has multiple cutouts. The cutouts are formed in the sleeve. The washer has two extensions. The extensions are formed on the washer and selectively engage the cutouts of the sleeve. The pivotal rod is mounted rotatably in the sleeve, is mounted securely in the washer and holds the washer between the pivotal rod and the sleeve. When the monitor pivots to open relative to the main frame of the portable computer, the extensions of the washer engage the cutouts of the sleeve to hold the monitor at a desired visual angle.
