Computer assume familiarity with the general terminology associated with personal computers and
with the safety practices and regulatory compliance required for using and modifying electronic
equipment.

personal injury or equipment damage.
3. 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.
4. 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
1. Do not leave the LCD directly facing the sun for a long period of time as it can damage the LCD.
2. Do not scratch the LCD or exert pressure on it. This could cause malfunction.
3. 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.
4. 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.

6. 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.
