A multi-stage hinge assembly includes a first coupling member adapted to fix with a portable computer and receivable with a second coupling member, a plurality of support members, a first positioning member, a plurality of resilient frictional devices, a second positioning member, a first position limiting member, a second position limiting member and a retainer. The first positioning member and the second positioning member are adapted to provide differential frictional forces. The first position limiting member and the second position limiting member include a plurality of the V-shaped lubricant holes adapted to maintain lubricant therebetween regardless whether the second coupling member is rotated clockwise/anticlockwise with the first coupling member.
