An information handling system keyboard illuminates key values in each of plural keycaps with a backlight located below the plural keys and directed upward through the plural keys and having illumination that adjusts color temperature under management of a controller. A light sensor detects ambient light color temperature and communicates the ambient light color temperature to the controller, which executes instructions in non-transitory memory to adjust the backlight color illumination based on the detected ambient light color temperature to increase color contrast of backlight illumination relative to ambient light and thereby better highlight the key values on the keycap upper surfaces.

Information handling system keyboard color adjustable backlight

An information handling system keyboard backlight illuminates with a single mini-LED disposed under each of plural keyboard keys and having a penta directional illumination that illuminates directly at the key and coplanar a light guide material around the perimeter of the mini-LED. The light guide material in cooperation with a reflector below and a mask above provides indirect illumination at the periphery of the key for a more uniform key illumination. A substrate carried with circuits below the mini-LED powers the mini-LED so that a more bulky flexible printed circuit is not needed.

Systems and methods for a hack-proof security keyboard are described. In some embodiments, a keyboard module may include a first circuit configured to detect activation of a plurality of keys and a second circuit configured to detect activation of a subset of the plurality of keys, where the second circuit overlies the first circuit. In other embodiments, a method may include detecting an electrical signal received from a secondary membrane of a keyboard, where the keyboard includes a primary membrane configured to detect individual activation of any of a plurality of keys, and where the secondary membrane is configured to output the electrical signal in response to concurrent activation of a subset of the plurality of keys. The method may also include performing a selected action in response to the detection.

Hack-proof security keyboard

Systems and methods are disclosed for transitioning a magnetic keyboard between retracted and extended states using a retractable keyboard hinge structure. An information handling system may include a housing having a first housing portion and a second housing portion rotatably coupled by the retractable keyboard hinge structure. The first housing portion may include a magnetic keyboard, and a sliding plate including a plurality of magnets that may be disposed underneath the magnetic keyboard. The retractable keyboard hinge structure may include a first hinge and a first cam. The first hinge and the first cam, when the first housing portion is rotated in relation to the second housing portion, may cause the sliding plate to move in a first linear direction. In response to the sliding plate moving, the plurality of magnets may cause the magnetic keyboard to move in a second linear direction perpendicular to the first linear direction.

Systems and methods for a keyboard backlight module are described. In some embodiments, a keyboard backlight module may include: a Light Guide Plate (LGP), a reflector coupled to the LGP, and a light bar at least partially sandwiched between the LGP and the reflector.

Keyboard backlight module

A portable information handling system keyboard retracts from an extended position to a retracted position, the retracted position bring the keys into the portable information handling system housing to provide a compressed closed position of the housing. The keyboard keys are biased to the extended position with a metal dome that interacts with a scissor support structure.

Low profile information handling system keyboard

A portable information handling system keyboard rests on a support surface of a housing with securing actions taken from above the housing, such as by screws that insert through the keyboard and then into the housing. A lattice cover having key openings fits over the keyboard to align adapters of its bottom surface with posts extending from the support surface through openings formed in the keyboard. The adapters snap to the posts to couple the cover against the keyboard so that the cover bottom surface presses the keyboard against the information handling systems upper support surface.

Portable information handling system keyboard support assembly

Support foot apparatus that include a support foot structure that employs flexible flap members disposed on opposing sides of a central foot member, and that are configured for insertion into corresponding openings of a support foot location defined in an exterior surface of the chassis of an information handling system or other device or structure. Each of the flexible flap members may be provided with one or more securing apertures configured for placement over corresponding securing posts provided on an interior surface of the chassis to secure the flexible flap members of the support foot apparatus within the interior of the chassis at a support foot location to hold the central support body against an exterior surface of the chassis.
