practices and regulatory compliance required for using and modifying
electronic equipment.

Disconnect the system from its power source and from any
telecommunications links, networks, or modems before you open the system
or follow any of the procedures described in the online document
“Upgrading and Maintaining Your VAIO
®
Computer” . Failure to do so may
result in personal injury or equipment damage.

Electrostatic discharge (ESD) can damage disk drives, add-in cards, and
other components. Follow the procedures described in the online document
“Upgrading and Maintaining Your VAIO
®
Computer” only at an ESD
workstation. If such a station is not available, do not work in a carpeted area,
and do not handle materials that produce or hold static electricity
(cellophane wrappers, for example). Ground yourself by maintaining contact
with an unpainted metal portion of the chassis while performing the
procedure.

When removing a slot cover, be careful not to damage components on the
system board or add-in cards. You may need to temporarily remove add-in
cards that are next to the slot cover you want to remove.
On Handling an LCD Display

Do not leave the LCD directly facing the sun for a long period of time as it
can damage the LCD.

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 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.

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.
