About the LCD Screen (Built-in Display)
 Do not place the display near a strong magnetic force.
 Do not block the ventilation slots on the display.
 Using the computer in low temperature conditions may produce a residual image on the screen. This is not a
malfunction. When the computer returns to normal temperature, the screen returns to normal.
 A residual image may appear on the screen if the same image is displayed for a lengthy period of time. The image
disappears after a period of time. You can use a screen saver to prevent residual images.
 The screen becomes warm during operation. This is normal and does not indicate a malfunction.
 Do not leave the LCD in direct sunlight, as this may damage the screen. Use caution when using the computer near
a window.
 Do not exert pressure on the LCD or scratch the surface, as this may cause the screen to malfunction.
 The LCD screen is manufactured using high-precision technology. On occasion, you may see tiny black or colored
points on the LCD. This is normal and does not indicate a malfunction.
 Avoid rubbing the screen, as this can damage the LCD. Use a soft, dry cloth to clean the display.
