  • Patent number: 9459655
    Abstract: A laptop includes a screen and a base having a keyboard. An end of the screen is articulated to an end of the base via a rotating device; and a first distance between a bottom edge of the screen and a bottom edge of the keyboard is smaller than a second distance between a top end of the screen and the bottom edge of the keyboard when the screen is closed onto the base. A guide rail is provided at two sides of the base, and the screen is slidable along the guide rail. The rotating device includes an articulated shaft connected to the base; and at any position on the guide rail, the screen is rotatable about the articulated shaft. When the screen is closed onto the base, the display surface of the screen faces outwards, thus the user can use the laptop in a tablet computer mode.
