Convertible information handling system input device surface and support

A convertible information handling system transitions to tablet and tablet stand configurations having a keyboard with a friction enhanced surface disposed against a support surface, the keyboard resisting movement of the information handling system relative to the support surface. For example, the keyboard has a rubberized plastic outer surface on non-moving keys to effectively increase the surface area of the keyboard in contact with the support surface. In one embodiment, the friction enhanced surface has its friction characteristics increased when proximate a support surface and decreased when distal a support surface.
