Working with the notebook
► Raise the screen into a vertical position.
► Hold the screen as low as possible on both sides. Turn the screen to the left or right in the direction
of the arrow. At first you will feel some slight resistance, then it will turn easily and without friction.
► Rotate the display further until it has turned 180° and the hinge latches in.
