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 portable information handling system housing biases to the closed position by attracting a piece of ferromagnetic material disposed in a lid housing portion to a magnet in a speaker disposed in a main housing portion. A Hall sensor proximate the ferromagnetic material detects the speaker magnet in the closed position and communicates open or closed position detection through a flexible cable and hinge to an embedded controller in the main housing for execution of logic associated with open and closed positions, such as ACPI sleep and wake states.

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 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 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: 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: 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.

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. Haptic feedback to touch function row inputs is provided by a haptic device coupled directly to a bottom surface of the touch function row, such as with an adhesive. The haptic device couples to a housing cover portion with a brace that integrates a resilient member, such as a spring, to dampen vibration from a haptic vibration source to the housing cover portion.

Abstract: This disclosure describes systems, devices, apparatuses, and methods of adjusting a center of gravity associated with a user device, such as a gaming controller. A movable weight may be moved to a first position associated with a first center of gravity of the user device and to a second position associated with a second center of gravity of the user device. The movable weight may be moved manually or automatically. The center of gravity may be adjusted based on a gameplay event or context or based on a user event or context. The user may receive feedback from an application via the user device.

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 retaining nuts extending from the housing, the motherboard retained in an engaged position by a cooling fan that directs cooling airflow out an exhaust.

A metallic cooling channel exposed in the exhaust and thermally coupled to the CPU by a heat pipe provides an antenna ground plane and/or a floating portion that acts as a directional parabolic element.
