Abstract: A portable information handling system speaker mount has standardized contacts and mounting points to accept plural speaker types with different speaker characteristics to generate audible sounds driven by an audio subsystem with audio driver settings, such as speaker-type gains. When a speaker is inserted, the audio subsystem communicates a coil characterization signal to the speaker and then analyzes the coil response to identify the type of the speaker, such as by determining the resistance of the coil to a direct current signal or the impedance of the coil from a frequency-based signal. In one example embodiment, the coil characterization signal generates audible noise from the speaker that is detected by a microphone and analyzed to determine the speaker type identity.

Abstract: A camera integrates a magnet at one end of a housing to magnetically attract and attach the camera to a front side of a peripheral display, such as to support a video conference through an information handling system interfaced with the display. A camera dock couples to a top side of the display and includes a back privacy support having an area that blocks the camera module from accepting external light when the camera is placed in the dock with the camera module aligned towards the back privacy support. An end user places the camera with a field of view directed in front of the display to capture visual images and flips the camera module to face the back privacy support to secure the camera against capture of visual images.

Abstract: End users subscribe to use information handling systems having a selected of available performance characteristics defined by a component configuration selected to build the information handling systems in a portable housing having housing portions rotationally coupled by one or more hinges. A manufacturer meets subscriptions with information handling systems built from an inventory of new hinges, deployed hinges of information handling systems in use by subscribers, and separated hinges taken from returned information handling systems and re-used. End user subscriptions are met in part by building replacement information handling systems with separated hinges having a useful life remaining that aligns with end user hinge usage patterns tracked over time, benchmarked performance metrics and end user subscription performance characteristics.

Abstract: A portable information handling system keyboard is tested for wear to determine reuse or recycling by subjecting the information handling system to visual inspection performed by a camera that includes an evaluation of key wear based in part on a keyboard language in a key lattice. The key lattice couples to a keyboard frame over a membrane having contact sensors and extends plural keyboard language members towards the membrane that identify by contact against the membrane the language of the plural keys in the keyboard lattice.

Abstract: A portable information handling system includes a battery having a battery swell detection sensor to detect predetermined battery swell. In one embodiment, a conductive gasket on the battery upper surface during battery swell presses against sensor on a bottom side of a housing cover to indicate battery swell. In another embodiment, a strains gauge of a resistive foil having first and second terminal detects battery swell that introduces strain to the strain gauge that increases resistance to current passing between the first and second terminals. A processing resource of the information handling system executes instructions to detect the battery swell and to discard battery swell indications associated with inputs at a keyboard or touchpad coupled to the housing cover.

Abstract: A portable information handling system includes a battery having a pattern that aids in detection of battery swell, such as by capture of a visual image of the battery and pattern with a camera for comparison against a threshold of the pattern distortion that indicates excessive battery swell. For instance, the pattern is parallel lines of a strain gauge that detects strain introduced by battery swell. Distortion of the parallel lines by expansion of the battery due to swelling is detected by changes in distance between the parallel lines and confirmed with distances measured between the camera and the pattern by an infrared depth camera.

Abstract: A portable information handling system hinge is tested for wear to determine reuse or recycling by subjecting the information handling system to an acceleration and capturing a visual image of hinge movement in response to the acceleration. Excessive hinge wear is detected when housing movement exceeds a threshold distance or fails to achieve threshold dampening effect. After detection of hinge wear, when a hinge has sufficient torque for use in a selected of plural information handling system platforms, the hinge is reused, otherwise the hinge is broken down and recycled.

Abstract: A portable information handling system keyboard is tested for wear to determine reuse or recycling by capturing visual images of the information handling system and comparing color, material and finish wear with color, material and finish thresholds. Excessive keyboard wear is detected when housing when the image show excessive degradation from use that impacts potential reuse of the keyboard. Keyboard key wear is checked in part based upon a vertical position of the keyboard keys relative to a palm rest of the information handling system. Keyboard backlight illumination is checked to find any weak lights and is altered to highlight key wear for detection by the camera.

Abstract: An information handling system hinge has a modular and selectively separable core that couples to hinge mounts in an interchangeable manner so that core selection defines hinge characteristics, such as torque, detent orientation and stop orientation. A standardized mount accepts cores with different rotational characteristics for streamlined manufacture of information handling systems and improved reuse and recycling of hinge components. A stop included with the hinge limits hinge rotation to a defined orientation, such as 135 degrees, and is released by engagement with a tool form exterior the housing to allow rotation past the defined orientation and thereby release a display from the housing.

Abstract: An information handling system having a display magnetically couples a peripheral camera to the display with a ferromagnetic material disposed behind the display. A dock couples to the display and has a curved base on which a cylindrical housing of the peripheral camera rests. A power pogo pin and ground pogo pin extend from the dock rear support front surface to contact a power concentric ring and a ground concentric ring formed in the peripheral camera cylindrical housing rear side. The power pin contacts the power concentric ring and the ground pin contacts the ground concentric ring through 360 degrees of rotational orientation of the cylindrical housing in the dock curved base.

Abstract: In some examples, a sensor node is mounted to a wood item inside a wall of a building. The sensor node measures, using a thermometer, an ambient temperature inside the wall of the building, measuring, using a hygrometer, an ambient humidity inside the wall of the building; and measures, using an ohmmeter, a resistance of the wood item between two metal fasteners used to mount the sensor node to the wood item. The sensor node determines, based on the resistance, a moisture content of the wood item. The sensor node determines, based on the ambient temperature, the ambient humidity, and the moisture content, that conditions inside the wall of the building are conducive to pest activity and sends, using a communications interface, a notification that conditions are conducive to pest activity. The notification includes the ambient temperature, the ambient humidity, and the moisture content.

Abstract: In some examples, a sensor node measures, using a thermometer, an ambient temperature of a location in which the wood item is located, measures, using a hygrometer, an ambient humidity of the location, measures, using an ohmmeter, a resistance of the wood item between two metal fasteners used to mount the sensor node to the wood item, determines, based on the resistance, a moisture content of the wood item, and determines, based on the ambient temperature, the ambient humidity, and the moisture content, whether conditions are conducive to pest activity. If conducive, the sensor node uses a microphone that is coupled to the wood item to capture audio data and determine whether the audio data indicates pest activity. If pest activity is detected, the sensor node sends a notification of pest activity, the notification includes the ambient temperature, the ambient humidity, the moisture content, and the audio data.

Abstract: An information handling system motherboard interfaces with other components, such as an I/O board and a display, through a cable backplane having an M.2 edge card connector and coupled to a housing with a snap in cable retainer. The motherboard slides into position at the housing to have an edge card extending past one side to engage into the edge card connector. The cable backplane is a flexible cable that routes through the hinge up lid housing portion of the system to communicate with a display and/or camera in the lid portion, or to route back into the main housing portion to communicate with an I/O board.

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.
