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.

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.

Spring biased connectors of the camera bias against contact pads formed in the display substrate to send the camera visual images through the communication link in the display substrate and then a display cable to the motherboard.

Abstract: An information handling system keyboard membrane integrates a high speed communication link, such as a differential serial pair, that communicates between a motherboard and a port exposed at a side of the information handling system housing. A communications hub in the membrane, such as a Thunderbolt hub, coordinates communication of information through the high speed link and communication of key inputs to the motherboard.

Abstract: Systems and methods described herein may provide a system that enables game play or other application sessions from a set of candidate game hosts and environments to consumption devices of a user's choice while the user moves about their home between the different environments. The system may employ methods to determine where a user is located within the home, availability and selection of candidate game hosting and target environments, homing and direction of related I/O and audio-visual (AV) content for consumption. The solution accommodates multiple users simultaneously within the home, whether in single player, multiplayer using the same screen, or multiplayer using separate screen games. The solution may configure AV and input/output (I/O) such that multiple users can consume one or multiple games in the home simultaneously, whether in separate locations or when seated together in front of the same consumption device.

Abstract: A control method for tracking a camera include following steps. At least one image involving a calibration chart is captured by a camera. A first trackable device attached to the camera is tracked by a tracking station to generate a first rotation-translation matrix. A second trackable device attached to the calibration chart is tracked by the tracking station to generate a second rotation-translation matrix. A third rotation-translation matrix is generated according to the calibration chart appeared in the at least one image. A fourth rotation-translation matrix is calculated between the camera coordinate system and the first trackable device according to the first rotation-translation matrix, the second rotation-translation matrix and the third rotation-translation matrix. The fourth rotation-translation matrix is utilized to track the camera.

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.

The input device may generate haptic feedback based on the detected adjustment to the position of the damping medium of the linear magnetic ram of the input device.

Abstract: Methods and systems for providing computer implemented services using user input are disclosed. To obtain the user input, a human interface device may be used. Interpretation of actuation of the human interface device may be based on a location of the human interface device relative to a sensing system when the actuation is performed. Sensing elements integrated into the sensing system may be used to obtain user input from the human interface device at the location, the user input then being interpreted based on the location to provide the computer implemented services.

Abstract: Security on an information handling system may be improved by using a stylus. A stylus provides unique information about a user that may not be acquired by an information handling system through other methods. For example, a user's handwriting is often unique to that user and may provide a security check on the information handling system to confirm the user's identity. Further, the stylus is usually held in the user's hand and may be used to check the user's fingerprint to confirm the user's identity. These authentication techniques, including fingerprinting and handwriting, may be used to maintain persistent authentication while the user is using the stylus. As the user continues to interact with the information handling system with the stylus, the stylus continues to receive the user's fingerprint and handwriting, which may be checked to confirm the user of the information handling system is still the expected user.

Abstract: An apparatus includes a memory and one or more processors coupled to the memory. The one or more processors are configured to determine a plurality of input areas of a touchpad associated with a computing device. The touchpad is associated with a sensitivity setting that indicates a first sensitivity for a first input area of the touchpad and that further indicates a second sensitivity for a second input area of the touchpad that is different than the first input area. The one or more processors are further configured to receive user input from a user input device associated with the computing device. The one or more processors are further configured to change the sensitivity setting based on the user input. Changing the sensitivity setting includes reducing the first sensitivity.

Abstract: A tablet information handling system selectively couples to a charging stand and charging dock with opposing sets of spaced magnets to have magnetic attraction hold a wireless charging receiver aligned with a wireless charger. Magnetic attraction is greatest when the tablet information handling system couples in a landscape or portrait orientation and is reduced for removal of the tablet information handling system by rotating to an offset orientation so that magnets align with opposing spaces, resulting in a reduced magnetic attraction. A sensor disposed in a space detects the offset rotation by detecting the increased magnetic flux of the magnet aligning with the space so that a user interface can provide an end user with an indication that the tablet information handling system is positioned for separation from the charging stand or charging dock.

Abstract: A computing device may segment an input area of an user input device (e.g., the surface of a trackpad) into multiple subsets. At a given time, the computing device may use one of the multiple subsets for mapping to a display device (e.g., instead of mapping the entire input area to the display device). To illustrate, based on receiving user input in one of the multiple subsets, the computing device may map that subset to the display device so that the subset is represented at the display device (e.g., without representing the other subsets at the display device). By segmenting the input area, an aspect ratio of a segment may be matched to an aspect area of the display device. Accordingly, distortions associated with an aspect ratio mismatch between the input area and the display device may be reduced or avoided.
