Abstract: The present invention relates to a portable computer having a base and a display panel coupled by a hinge structure. The base has a bottom and a top housing. The bottom housing has bottom bosses with holes extending upwardly. A circuit board has holes aligned with the bottom housing holes. The top housing also has holes aligned with the bottom housing. A top housing is coupled to the circuit board and the bottom housing. A display panel incorporating a display screen is attached pivotally to the top housing with a hinge assembly. The hinge assembly has holes aligned with the holes of the bottom housing. A pair of caps are coupled to the top housing to cover the hinge assembly. Each cap has a boss with a hole aligned with the hole of the bottom. A screw is inserted from outside the bottom housing and through the circuit board, the top housing, the hinge assembly, and finally coupling with the cap boss. A single set of screws attach the base portions and pivotally attaches the display panel with the base.
