Abstract

Techniques for mobile device power state are described. In one or more implementations, a mobile device includes a computing device that is flexibly coupled to an input device via a flexible hinge. Accordingly, the mobile device can operate in a variety of different power states based on a positional orientation of the computing device to an associated input device. In one or more implementations, an application that resides on a computing device can operate in different application states based on a positional orientation of the computing device to an associated input device. In one or more implementations, techniques discussed herein can differentiate between vibrations caused by touch input to a touch functionality, and other types of vibrations. Based on this differentiation, techniques can determine whether to transition between device power states.
