Abstract: A portable information handling system power source has plural separate modules that removeably couple to each other to selectively provide external power from battery and AC power sources. A controller module includes logic to coordinate power transfer to and from an information handling system. An AC-to-DC adapter module couples to the controller module to provide power from an AC power source to the information handling system through the controller module, which coordinates power transfer with the information handling system. A battery power source module couples to the controller module to provide battery power, with the battery charged by power from either the information handling system or the AC-to-DC adapter module.

Abstract: An information handling system hinge provides friction against rotational motion to generate torque that regulates housing portion relative position. Friction is generated by compression of friction elements with a super elastic wire under tension. For example, a nickel titanium alloy wire under two to eight percent strain provides a relatively low spring rate having consistent compression even as wear reduces the size of the friction elements.

Abstract: A dual axis hinge assembly couples first and second hinges to each other with a central barrel and routes cables across hinge axles with cable channels formed in the axles. The dual axis hinge assembly rotationally couples information handling system housing portions to each other and routes cables between the housing portions distal the barrel by running the cables through a channel formed in each axle of one of the hinges with the cable entering one axle distal the barrel, routing through the axle to a position proximate the barrel, crossing the hinge to enter the other hinge axle proximate the barrel and routing though the other axle to exit distal the barrel.

Abstract: An information handling system integrated keyboard selectively retracts and extends keys based upon detected conditions, such as housing configuration, housing motion and end user indications. Extension and retraction shuttle plates motivated by actuator wires moves a sliding plate to extended and retracted positions that define the key positions. Nickel titanium alloy actuator wires shorten upon application of current to pull the shuttle plates to the extended or retracted positions that are maintained by a lock. Limit switches remove current at detection of a desired shuttle plate position. One or more controllers manage actuator wire operation based upon detected conditions and actuator wire temperature and electrical characteristics.

Abstract: A tablet information handling system detachable base couples with a tablet information handling system by inserting a trapezoidal-shaped support into a trapezoidal-shaped opening of the tablet information handling system. The smaller perimeter of the support has room to fit in the larger perimeter opening of the tablet information handling system for ease of insertion, yet the support snuggly fits into the opening after complete insertion. A latch couples the support with an inclined lower surface so that pulling on the tablet information handling system without releasing of the latch translates into a more secure latch coupling. A latch release timer allows one-handed detachment by maintaining the latch in a released position for a predetermined time after latch release actuation.

Abstract: A fluid delivery system configuration is described for use with an array of liquid submersion cooled electronic devices disposed in a rack, such as an array of liquid submerged servers. The fluid delivery system allows for the pumping system to generate pressure and flow of the cooling system fluid at slightly higher levels than is necessary for the worst case device/position within the array and to provide for uniformity of delivery pressure and coolant flow to each and every device within the array.

Abstract: An information handling system includes a processor and receptacle module. The processor to receive a request to safely remove a hardware component coupled to the information handling system, to execute a safely remove process, and to send a latch release signal in response to the process being completed. The receptacle module including a receptacle, a latch, and a component. The latch is biased in a first position with a hook of the latch being located within a notch of the receptacle. The latch to rotate from the first position to a second position in response to a plug being inserted into the receptacle, and to snap back to the first position in response to the plug being fully inserted into the receptacle. The component to continually exert a first force on the latch to move the latch to the second position while the latch release signal is received.

Abstract: A portable information handling system integrated button touch pad provides consistent functional displacement with support of a touch surface from separate main and click brackets. The click bracket provides consistent displacement relative to a housing and a support plane so that an integrated button touch pad adapts to different housing sizes and materials with a common support arrangement of the touch surface and a common functional displacement feel provided by flexing of a main bracket that directly supports a touch pad relative to fixed click pad position.

Abstract: A portable information handling system hinge rotationally couples lid and main housing portions to each other with one or more shafts that rotate relative to the housing portions and/or each other. Threads integrated along the shaft length engage off axis with a friction element that generates resistance to housing portion rotational movement. Placement of the friction element in length and/or width vectors aids reduction of the system housing height vector.

The third server is inserted within the second slot of the adaptor assembly, and includes a second communication fabric. The height of the third server is substantially equal to a quarter of the height of the bay.
