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 housing cover having guide structures with stops disposed on opposing sides and aligned to engage with rails of the housing to slide to a cover position over the housing defined by the position of the stops. The keystone assembly completes the housing cover enclosure of the housing interior by coupling in a gap between the housing cover and housing at one side and overlapping the keyboard assembly to retain the keyboard assembly in position.

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.

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 that has contact switches to detect key input presses and is supported by a housing cover that extends members into a housing interior to hold components in position, such as a speaker. The speaker has spring-biased connection pins with a dampener at the speaker housing to dampen vibrations. Contact pads extending from the keyboard membrane communicate speaker signals to the speaker to play audible sounds though the spring-biased connection pins.

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.
