On Moisture Condensation
If your computer is brought directly from a cold location to a warm one, moisture
may condense inside your computer. In this case, allow at least an hour before
turning on your computer. If any problem occurs, unplug your computer, and
contact your Sony Service Center.
On Upgrading the Computer System
❑ The procedures described in the online manual, Upgrading and Maintaining
Your VAIO Digital Studio™ 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.
❑ 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 manual, Upgrading
and Maintaining Your VAIO Digital Studio™ Computer. Failure to do so
may result in personal injury or equipment damage.
❑ Electrostatic discharge (ESD) can damage disk drives, add-on cards, and
other components. Follow the procedures described in the online manual,
Upgrading and Maintaining Your VAIO Digital Studio™ 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 (for example, cellophane wrappers). Ground yourself by
maintaining continuous 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-on cards. You may need to temporarily remove add-on
cards that are next to the slot cover you want to remove.
❑ 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.
