text: on my another computer, the display is get rotated by 180 degree (up side down) how to rectify the problem? my 9 month son, while playing with it pressed some keyboard keyes and the display gate rotated by 180 degrees. now it is becoming very difficult to do work with it. the short key to get the display back to normal is: ctrl+alt+up arrow key  and since you have raised this question here's some additional information on display rotation: ctrl+alt+up arrow key - normal display ctrl+alt+down arrow key - 180 deg rotation ctrl+alt+left arrow key - 270 deg rotation ctrl+alt+right arrow key - 90 deg rotation.  cheers!
