This is a very n00be question. I see the "clock wise" arrow near the screen hinge of T4020D. I just got this tablet PC yesterday and I am still learning my way with this new machine. The manual says the screen has to be rotated clockwise from the notebook form to the tablet form. For the other way (going back to the notebook form, rotate the screen the other way.
I am curious to know if the screen rotoates either direction (both clockwise and counter clockwise from the notebook to table form). As I get used to this machine and start handling it without looking at it (ie. it's like driving a car; you don't look at the shifter position as you know it without looking at it, I am concerned I might try to rotate the other way.
