Markings appear on
the LCD screen.
These marks may have come from contact with
the keyboard or Touch Pad while the display has
been closed. You should try to remove the marks
by gently wiping the display panel with a clean
dry cloth or, if this fails, with a good quality LCD
screen cleaner. In this latter instance you should
always follow the instructions with the screen
cleaner and always ensure you let the LCD
screen dry properly before closing it.
