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.

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.

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.

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.

An input device for an information handling system ay detect an adjustment to a position of a damping medium of a linear magnetic ram of the input device. 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.

Systems and methods for adjustable haptic damping positioning

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.

System and method for magnetic sensing multiconfiguration data processing systems

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.

A main housing portion of a portable information handing system. The main housing portion includes: a bottom cover portion; and, a top cover portion coupled to the bottom cover portion, the top cover portion comprising a full palm rest trackpad, the full palm rest trackpad comprising a touch printed circuit board; a sensor film portion electrically coupled to the touch printed circuit board; and, a plurality of piezo components extending across a width of the full palm rest trackpad, the plurality of piezo components being electrically coupled to the touch printed circuit board, the plurality of piezo components, each of the plurality of piezo components performing a haptic function.

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. The keyboard assembly includes a membrane having plural input sensors and a capacitive touch sensor that interface with a communications hub, such as a USB communications hub coupled to the membrane, that communicates both the keyboard inputs and touchpad inputs to a motherboard through first and second contacts that support a differential serial pair.

A portable information handling system includes a keyboard having a first set of conventional keys with a first travel distance to impact a membrane, such as keys having rubber dome biasing devices, and a second set of keys having a second smaller travel distance to impact the membrane with an alternative biasing device and haptic feedback to reinforce an input feel for an end user. In one example embodiment, the second set of keys are biased upward with a compressible foam with the membrane raised by a platform structure under the second set of keys and a piezoelectric device under the membrane for each key to provide a vibration when the membrane detects an input.
