| 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. | |

| Description: | |
| This attribute returns a string with the current device posture, as indicated by the embedded controller. Currently | |
| returned posture states are: | |
| - "closed": The lid of the device is closed. | |
| - "laptop": The lid of the device is opened and the device | |
| operates as a normal laptop. | |
| - "slate": The screen covers the keyboard or has been flipped | |
| back and the device operates mainly based on touch input. | |
| - "tablet": The device operates as tablet and exclusively | |
| relies on touch input (or external peripherals). | |
| - "<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 | |
