Dell™ Latitude™ XT2 Service Manual
Notebook Mode
Your Tablet-PC can be used either in notebook mode or tablet mode. To use your Tablet-PC in notebook mode, open the display until it reaches a comfortable
viewing angle as in the image to the right, and use the keyboard and display as you would those of any other notebook computer.
Tablet Mode
Your Tablet-PC converts from notebook mode to tablet mode with a 180-degree clockwise twist of the display’s rotating hinge.
When you convert your Tablet-PC between notebook and tablet modes, the screen orientation of your Tablet-PC will automatically change according to the
settings you have established in the Dell Control Point System Manager application or the Windows Vista Pen and Tablet settings application, most commonly
from landscape (notebook mode) to portrait (tablet mode).
CAUTION: Forcing the hinge beyond the 180-degree point will damage the Tablet-PC.
Open the display of the Tablet-PC until it
reaches a 90-degree angle, perpendicular
to the base.
Brace the base with one hand on the palm rest, grasp the top of the
display with the other hand, and, following the directional arrow
inscribed on the hinge cover, turn the rotating hinge clockwise 180
degrees until you feel the display engage securely.
Lay the display assembly on the base
with the display facing upwards.
