My client has a this laptop that is virus-free and works fine. Just one issue: upon startup, the screen is rotated 90 degrees. He's quite knowledgeable and has tried everything I suggested we try in the short few minutes I had to concentrate on that problem (other, user-centered issues demanded my time).
He has adapted to the problem by pressing the screen orientation button in the top row to get the screen oriented correctly.
I've done the desktop-right-click drill to change the orientation, but it comes back wrong upon the next startup.
