Go into the Desktop Manager and look for the display properties.
It ought to be in the Intel Graphics Manager, most probably a blue icon in the tray next to the time.
Change orientation by rotating it either clockwise or anti clockwise, they ought to have 90 and 180 Degrees mentioned there. Click on one of them and apply.
Check to see if it looks like the orientation has come back to normal and reply.
