DETAILED DESCRIPTION
Tablet computing systems having video displays may be portable and used in a variety of locations. Tablet computing systems may include smartphone devices having video displays, tablet computers having video displays, and the like. Users may want to select different viewing orientations of the video display based on use preferences, tablet locations, and the content being viewed. Accessary devices such as display stands, tablet covers, and the like, may be used to provide viewing orientations to view the video display. However, at times, accessary devices may be inconvenient with which to travel, lost, increase the cost of the tablet computing system experience, and offer few viewing orientations to view the video display of the tablet computing system.
In examples, a tablet computing system includes a main body having a front side and a back side, a video display disposed on the front side, and a battery cavity disposed on the back side to receive a battery to supply power to the main body. The video display may display images. The battery cavity may include a first cavity end to correspond to an outer end of the main body. The tablet computing system may also include a hinge member having a first hinge end coupled to the first cavity end and a second hinge end to removably receive a first battery end of the battery. The hinge member may cause the battery to rotate about the first cavity end to form an adjustable angle between the battery and the battery cavity. The video display may be selectively placed in one of a plurality of viewing orientations to view it based on an amount of the adjustable angle. Thus, the battery may function as a torqued hinge stand so that a user may select from the plurality of viewing orientations to view the video display without an accessory by rotating the battery away from and towards the battery cavity. Accordingly, travel inconveniences, lost accessories, and an increased cost of the tablet computing system user experience may be reduced.
