Hi. I was cleaning the keyboard, turned it upside down to clean, and all of a sudden the display turned itself upside down. The keyboard wasn't working right, so I changed it to another keyboard, which seems to be doing just fine. But I can't get the display right side up. I did follow a similar thread and learned that the control-alt-arrow key controlled orientation of the display. Now I can get it to display longways top to bottom, but I still can't get it to display longways side to side. I just want to get back to normal. Any suggestions? Many thanks. Maggie
