- Description:
- This attribute returns a string with the current type-cover
- or device posture, as indicated by the embedded controller.
- Currently returned posture states are:
- - "disconnected": The type-cover has been disconnected.
- - "closed": The type-cover has been folded closed and lies on
- top of the display.
- - "laptop": The type-cover is open and in laptop-mode, i.e.,
- ready for normal use.
- - "folded-canvas": The type-cover has been folded back
- part-ways, but does not lie flush with the back side of the
- device. In general, this means that the kick-stand is used
- and extended atop of the cover.
- - "folded-back": The type cover has been fully folded back and
- lies flush with the back side of the device.
- - "<unknown>": The current state is unknown to the driver, for
- example due to newer as-of-yet unsupported hardware.
- New states may be introduced with new hardware. Users therefore
- must not rely on this list of states being exhaustive and
- gracefully handle unknown states.
