A portable computer includes a main body including a bottom sheet and a panel which cooperatively form a receiving cavity, a display, a pivot shaft connecting the main body to the display, a keyboard, a pushing member including a pushing body, two connecting rods, and two restricting members. The panel includes a first surface facing the bottom sheet. The keyboard includes a first side, a second side, a flexible blocking member, and at least one auto-flick pivot on the second side. The restricting members are received in the receiving cavity corresponding to the connecting rods. Each restricting member includes a liftable restricting portion positioned on the bottom sheet. The auto-flick pivot connects the keyboard to the main body. Each connecting rod movably connects the keyboard to the main body. The pushing body is movably connected to the first surface and moves from a first position to a second position.
