Precautions
User Guide
If the computer is brought directly from a cold location to a warm one, moisture may condense inside your computer. In this 
case, allow at least one hour before turning on your computer. If any problems occur, unplug your computer and contact VAIO-
Link.
Make sure you disconnect the power cord before cleaning the computer.
As you may lose important data once your computer is damaged, you should back up your data regularly. You can restore most 
of the original application programs from the supplied disc (read the Troubleshooting Guide for details).
On handling LCD screens
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 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.
