Precautions

On handling the LCD screen

Do not leave the LCD facing the sun as it can damage the LCD. Be careful when using the computer near a window.
Do not scratch the LCD or exert pressure on it. This could cause a malfunction.
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 residual image
disappears in a while. You can use a screensaver to prevent residual images.
The screen becomes warm during operation. This is normal and does not indicate a malfunction.
The LCD is manufactured using high-precision technology. You may, however, see tiny black points and/or bright points (red, blue,
or green) that continuously appear on the LCD. This is a normal result of the manufacturing process and does not indicate a
malfunction.
Avoid rubbing the LCD screen, as this can damage the screen. Use a soft, dry cloth to wipe the LCD screen.
