Upgrading the computer system
❑ The upgrading procedures described in the online manual, 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 telecommunications
links, networks, or modems before you open the system or follow any of the
upgrading procedures described in the online manual. 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 upgrading procedures described in the online
manual while working at an ESD workstation. If such a station is not
available, use these precautions:
❑ Avoid working in a carpeted area.
❑ Do not handle materials that may produce or hold static electricity, such
as 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.
Handling a display
❑ Do not change the display refresh rate to 85 Hz, as DVD playback and the
DVgate software may not function correctly. Sony recommends that you
keep your display at the preset, optimal refresh rate (75 Hz).
❑ Do not place the display near a strong magnetic force.
❑ Do not block the ventilation slots on the display.
❑ 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.
