| 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. |
