Abstract
An information handling system stylus performs touch inputs at a touchscreen display with an active writing tip that receives a capacitive signal from a processing resource, such as an ASIC. A tip position controller selectively retracts and extends the writing tip at an opening formed in a tip cap disposed at the end of the stylus. A power interface cuts off power to the processing resource when the writing tip retracts and applies power to the processing resource when the writing tip extends.
