Abstract: A portable electronic device includes a main portion, a display portion and a hinge module. The display portion is pivotally connected with the main portion by the hinge module. A first hinge member has one end secured to the main portion. A second hinge member has one end, pivotally connected with the other end of the first hinge member, and the other end secured to the display portion, wherein the second hinge member comprises a guide slot. A resilient member is disposed around the other end of the first hinge member. The resilient member includes a fastening end and an actuation end. The fastening end is secured to the first hinge member. The actuation end is disposed within the guide slot of the second hinge member. The guide slot is operable to drive the actuation end so as to deform the resilient member.
