VAIO MX Computer User Guide ❑ 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 CRT display ❑ Do not change the CRT display refresh rate to 85 Hz, as DVD playback and the DVgate software may not function correctly. Sony recommends that you keep your CRT 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. Handling an LCD display ❑ Do not leave the display directly facing the sun for a long period of time as it can damage the LCD screen. ❑ Do not scratch the LCD screen or exert pressure on it. This may cause damage to the screen or cause a malfunction. 88
