  • Patent number: 12613546
    Abstract: Methods and systems for providing computer implemented services using user input are disclosed. To obtain the user input, a passive human interface device may be used. The human interface device may encode information regarding actuations of the human interface device in magnetic field distributions emanating from the human interface device. The magnetic field distribution may be sensed to identify user input provided by a user of the human interface device. The user input may be interpreted in the context of different modes of operation of the human interface device. The user input may be used to provide the computer implemented services.

  • Patent number: 12596443
    Abstract: Methods and systems for providing computer implemented services using user input are disclosed. To obtain the user input, a passive human interface device may be used. The human interface device may include a trackball and a pair of magnets that may produce a magnetic field used to discern the user input. The pair of magnets may be mechanically coupled to the trackball and actuatable portions of the human interface device thereby facilitating both rotation and translation, respectively, of the pair of magnets responsive to actuations by a user. The rotation and translation of the pair of magnets may be sensed and used to identify user input provided by the user.

  • Patent number: 12578772
    Abstract: An information handling system monitors current at plural current sensors during each of plural predefined events, such as power up and boot, to detect power anomalies that indicate failing components, such as bad charger, bad power rail, bad motherboard and/or back cover deck. Current during a boot event is compared to a baseline value for the event, such as a value measure and stored at manufacture of the system, and/or an average of current measured for a predetermined number of previous events. In one embodiment, a separate analysis is performed based upon whether the system boots from battery power or external alternating current adapter power.

  • Patent number: 12533575
    Abstract: Systems and methods described herein may provide a system that enables determining of room contours based on location tags and path information for paths traveled between the location tags. A computing device may receive identifiers for a plurality of location tags added to an environment and may receive path information for a plurality of paths between the plurality of location tags. The computing device may identify a plurality of room contours based on the path information and may determine, based on the plurality of room contours and at least one of the plurality of location tags, a display for use in a computing session.

  • Patent number: 12499022
    Abstract: An information handling system display cable communicates visual information from a motherboard to a display by defining link parameters with a link training, such as through a DisplayPort eDP link training. A link training failure rate is tracked when a link fails and is re-trained, including link parameters like bitrate. The link training failure rate and link parameters are analyzed to evaluate the display cable condition, such as for reuse or recycling. In one embodiment, the display cable link training failure rate and parameters are tracked in display non-transitory memory and downloaded when the display ships to a repair center.

  • Patent number: 12468440
    Abstract: A portable information handling system includes a touch function row between a keyboard and a display that accepts touches at plural locations to initiate an on-screen-display user interface for a selected of plural functions based upon a touch location. The touch locations may be identified with illumination points and unlabeled as to an associated function since the function associated with a touch location is presented at the display. Alternatively, a secondary display presents function key images at the touch function row. The on-screen-display user interface presents different control interfaces when touches include multiple fingers and drag versus non-drag inputs.

  • Patent number: 12446184
    Abstract: A portable information handling system is assembled and disassembled by a keystone assembly that couples at an upper surface of the portable housing to overlap a keyboard assembly that covers processing components disposed in the portable housing. A motherboard couples to the portable housing under the keyboard assembly with openings aligned to insert over retaining nuts extending from the housing, the openings having a varied size so that the motherboard slides between released and engaged positions. A cooling fan couples to the motherboard adjacent to one side to retain the motherboard in the engaged position and is removed to allow the motherboard to slide to the released position. Plural cooling fans interface in series with the motherboard to provide additional cooling capacity.

  • Publication number: 20250244867
    Abstract: A portable information handling system includes a touch function row between a keyboard and a display that accepts touches or proximity detection at plural locations to initiate an on-screen-display user interface for a selected of plural functions based upon a touch location. The touch and/or proximity locations may be identified with illumination points and unlabeled as to an associated function since the function associated with a touch and/or proximity location is presented at the display. Alternatively, a secondary display presents function key images at the touch function row. The on-screen-display user interface presents different control interfaces when touches include multiple fingers and drag versus non-drag inputs.
