Screen rotation
You can rotate the display panel as you please.
• The orientation of the display automatically changes (alternating between
portrait and landscape mode) in response to how you hold the computer.
Note: Some software does not support screen rotation and will cause
the screen to appear abnormal. If this happens, lock the screen to
prevent rotation or refrain from rotating the screen.
• Use the screen rotation lock button on the top edge of the computer to prevent
automatic display rotation. (See illustration below.)
