Notes on Use 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 a CRT Display
Do not place the display near a strong magnetic force.
Do not block the ventilation slots on the display. On Using the Hard Disk Drive
