Portable information handling system stylus dock

1. An information handling system comprising:

a lid housing portion integrating a display;

a main housing portion integrating processing components operable to process information, the processing components interfaced with the display to present the information as visual images;

a mono barrel hinge rotationally coupling the lid housing portion and main housing portion to rotate between closed and open positions, the mono barrel hinge having first and second dual axis hinge elements coupled to each other by a mono barrel member, the mono barrel member forming a depression shaped to accept a stylus, the first and second dual axis hinge elements both disposed in an interior of the mono barrel member, each of the first and second dual axis hinge elements having a first bracket extending out of the mono barrel member to couple to the lid housing portion and a second bracket extending out of the mono barrel interior to couple to the main housing portion; and

a sensor integrated in the mono barrel hinge and interfaced with the processing components, the sensor operable to detect presence of a stylus in the depression;

wherein the processing components apply a first touch sensitivity to detect touches at the display if the stylus is present and a second touch sensitivity to detect touches at the display if the stylus is not present.

2. The information handling system of claim 1 further comprising:

a stylus having a capacitive tip to input against the display;

wherein the stylus fits into the depression with the lid and main housing portions rotated to a closed position.

3. The information handling system of claim 2 further comprising:

a magnet integrated in the stylus; and

ferromagnetic material integrated in the depression, a magnetic attraction between the magnet and ferromagnetic material biasing the stylus into the depression.

4. The information handling system of claim 2 wherein the depression conforms against the stylus to maintain the stylus in the depression.

5. The information handling system of claim 1 wherein touch sensitivity comprises a touch detection scan rate of the display.

6. The information handling system of claim 1 wherein the mono barrel member comprises:

an inner member disposed proximate the display and having the depression;

an outer member disposed distal the display and having positioning guides for aligning the first and second hinge elements; and

one or more coupling devices to couple the inner member to the outer member with the first and second hinge elements captured between the inner member and outer member.

7. The information handling system of claim 6 wherein the inner member further comprises:

a first sidewall defining the depression proximate the display; and

a second sidewall defining the depression proximate a keyboard integrated in the main housing portion, the first sidewall taller than the second sidewall.

8. The information handling system of claim 7 wherein the second sidewall cooperates with the main housing portion to restrict removal of the stylus from the depression until the lid and main housing portions rotate greater than a predetermined angle.

9. A method for using a stylus with an information handling system, the method comprising:

rotating first and second housing portions to an open position that exposes a depression formed in a barrel hinge, the barrel hinge rotationally coupling the first and second housing portions to each other with first and second dual axis hinge elements disposed in an interior of a barrel member, each of the first and second dual axis hinge elements having first and second brackets extending out of the interior to couple with the first and second housing portions;

placing the stylus in the depression;

rotating the first and second housing portions to a closed position that encloses the depression within the first and second housing portions to retain the stylus in the depression;

sensing presence or absence of the stylus in the depression;

applying a first touch detection sensitivity at a display of the information handling system if the stylus is present;

applying a second touch detection sensitivity at the display if the stylus is absent; and

detecting touches at the display with each of the first and second touch detection sensitivity.

10. The method of claim 9 further comprising retaining the stylus within the depression by magnetic attraction between the stylus and barrel hinge.

11. The method of claim 9 further comprising retaining the stylus within the depression by engagement of the stylus against the sides of the depression.

12. The method of claim 9 further comprising:

retaining the stylus in the depression through a first range of angular relationship of the first and second housing portions by engagement of the stylus against the first housing portion; and

releasing the stylus from the depression through a second range of angular relationship of the first and second housing portions by disengagement of the stylus from the first housing portion.

13. The method of claim 9 wherein the first housing portion integrates a keyboard, the second housing portion integrates a display and the depression sidewall proximate the keyboard exposes the stylus to selectively engage against the first housing portion through a predetermined range of rotational movement.
