+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
