`ABSTRACT
`A portable computer that is configurable between a plurality
`of display modes including a laptop mode (in which the
`portable computer has a conventional laptop appearance) and
`an easel mode in which the base of the computer and its
`display component stand vertically forming an inverted “V”
`The portable computer includes a hinge assembly that
`couples the display component to the base of the computer,
`and allows the display component to be rotated about an axis
`along an interface between the display component and the
`base to configure the portable computer between a closed
`position, the laptop mode and the easel mode. The portable
`computer further comprises a scroll wheel and optional navi
`gation buttons that permit a user to control or manipulate
`various aspects of operation of the portable computer (such as
`Volume or display brightness) and/or content displayed the
`computer.

`along an interface between the base and the display compo
`nent. Unlike the computers discussed in U.S. Pat. No. 6,266,
`236 and U.S. Pat. No. 6,771,494 above, the portable computer
`according to embodiments of the invention does not require
`an arm assembly, nor multiple, different hinge assemblies to
`be configured into the different modes. Furthermore, the por
`table computer according to embodiments of the invention is
`capable of different display modes and different functionality
`in the different configurations, as discussed below.
`Further aspects and embodiments are directed to a portable
`computer having an embedded scroll wheel that can be con
`figured to allow a user to control various features and func
`tionality of the portable computer. For example, as discussed
`further below the scroll wheel can be used to navigate among
`information displayed on the portable computer's display
`and/or to alter operating modes of the portable computer,
`and/or to control features such as Volume, display brightness,
`etc.
`According to one embodiment, a portable computer is
`configurable between various modes, including a closed
`mode, a laptop mode, an easel mode, a flat mode and a frame
`mode. The portable computer may comprise a display com
`ponent including a display screen, a base, and a hinge assem
`bly at least partially housed within the base and configured to
`pivotably couple the display component to the base. The
`display component may be rotatable about alongitudinal axis
`running along an interface between the display component
`and the base. In the closed mode, the display screen may be
`disposed Substantially against the base, and rotating the dis
`play component about the longitudinal axis up to approxi
`mately 180 degrees from the closed mode may configure the
`portable computer into the laptop mode. Rotating the display
`component about the longitudinal axis beyond approximately
`180 degrees axis from the closed mode may configure the
`portable computer into the easel mode.
`In one example of the portable computer, the display com
`ponent is rotatable about the longitudinal axis up to approxi
`mately 320 degrees from the closed mode. In another
`example, the portable computer comprises a display orienta
`tion module that displays content on the display Screen in one
`of a plurality of orientations relative to the longitudinal axis.
`The orientation of the displayed content may be dependent on
`the current display mode of the portable computer, or may be
`configurable responsive to a user input. The portable com
`puter may further comprise a mode sensor which detects a
`current display mode of the portable computer, and the dis
`play orientation module may display content on the display
`screen in an orientation dependent on the current display
`mode detected by the mode sensor. Depending on the hinge
`assembly used, the longitudinal axis may comprises multiple
`parallel axes, and the hinge assembly may be configured to
`permit rotation of the display component about any of the
`multiple parallel axes to configure the portable computer
`between the plurality of display modes.
`Another embodiment is directed to a portable computer
`comprising a base, a display component rotatably coupled to
`the base, and means for rotating the display component in a
`single direction relative to the base to configure the portable
`computer between a laptop mode and an easel mode.
`In another embodiment of a portable computer config
`urable between multiple modes including a laptop mode and
`an easel mode, the portable computer comprises a display
`component, a base, and a hinge assembly configured to rotat
`ably couple the display component to the base. The hinge
`assembly may be configured to permit rotation of the display
`component about a single axis to configure the portable com
`puter between the laptop mode and the easel mode. In one
`
`1. Field of Invention
`The present invention relates generally to portable comput
`ers and, more particularly, to a portable computer that is
`configurable into different functional and positional modes.
`2. Discussion of Related Art
`Portable computers, such as laptop computers or notebook
`computers, have become increasingly popular and ubiquitous
`in the home and workplace. Conventional portable computers
`most commonly have a “clam-shell’ configuration, with a
`base including the keyboard, various ports, connectors and/or
`inputs (e.g., for power and connecting peripheral devices),
`and the majority of the electrical components (e.g., the central
`processing unit and memory), and a display component piv
`otably coupled to the base by a hinge. The display component
`is movable about the hinge between a closed position, with
`the display screen positioned adjacent the keyboard, and an
`open position, with the display Screen inclined at a desired
`Viewing angle.
`Some portable computers are able to accept user inputs via
`a touch screen in addition to via conventional tools, such as a
`keyboard or mouse. The use of a touch screen to input data is
`sometimes referred to as operating in “tablet mode” because
`the computer is being used in a manner similar to a tablet of
`paper. U.S. Pat. No. 6,771,494 discloses a hybrid tablet-type
`portable computer that is capable of operating either as a
`normal laptop computer receiving user input via a keyboard
`("laptop mode'), or as a tablet computer receiving user input
`via a touch screen. The 494 patent further discloses that the
`display component of the computer is attached to the base of
`the computer by hinges that allow the display to be tilted
`relative to the base (for laptop mode), and to be rotated and
`folded against the base to configure the computer into tablet
`mode.
`Another variation of a portable computer with a moveable
`display is disclosed in U.S. Pat. No. 6,266,236. The 236
`patent discloses a computer including a base, a display mem
`ber and an arm assembly coupling the display member to the
`50
`base. According to the 236 patent, the arm assembly allows
`pivotable movement of the display member between a plu
`rality of positions, including a notebook mode configuration,
`a tablet mode configuration, a presentation mode configura
`tion, and a closed mode.
