Media care This section provides tips on protecting data stored on your CD's, DVD's and floppy diskettes. Following the simple precautions listed below will increase the lifetime of your media and protect the data stored on it. CD/DVDs 1. Store your CD's and DVD's in the containers they originally came in to protect them and keep them clean. Do not write on, apply a sticker to, or otherwise mar the surface of the CD or DVD that contains the data. Hold the CD or DVD by its outside edge or the edge on the center hole any fingerprints on the surface of the disc can prevent the drive from properly reading data. If your CD's or DVD's become dusty or dirty, wipe them with a clean dry cloth from the center hole outwards - do not wipe in a circular direction. If necessary, you can use a cloth that has been lightly dampened in water or a neutral cleaner but you must not use benzine, thinner or any similar cleaning solution. User's Manual 4-31 Satellite U500/U500D, Satellite Pro U500/U500D Floppy diskettes 1. Store your floppy diskettes in the container they came in to protect them and keep them clean. If a floppy diskette becomes dirty, clean it with a soft, lightly dampened cloth - do not use cleaning fluid. Never open the shutter or touch the magnetic surface of your floppy diskette - doing this could permanently damage it and lose data. Always handle floppy diskettes with care to prevent the loss of stored data. Always apply the floppy diskette label in the correct location and never apply a new label on top of an existing one - in this instance the label could come loose and damage the floppy diskette drive. Never use a pencil for writing on a floppy diskette label as the dust from the pencil lead could cause a system malfunction if it found its way onto the computer's components. In this instance, always use a felt-tipped pen and write the label first before applying it to the floppy diskette. Never put a floppy diskette in a location where water or other liquid may make contact with it, or where it is excessively damp - either of these conditions could cause data loss. Never use a wet or damp floppy diskette - this could damage the floppy diskette drive or other devices within the computer. Data may be lost if the floppy diskette is twisted, bent, or exposed to direct sunlight, extreme heat or cold. Do not eat, smoke, or use items such as erasers near your floppy diskettes as foreign particles inside the jacket of the floppy diskette can damage the magnetic surface. In view of this you should keep your floppy diskettes away from speakers, radios, televisions and other sources of magnetic fields. Sound system This section describes some of the audio control functions. Adjusting System Volume You can control the overall level of sound using Windows Volume Mixer. Adjust speaker volume by moving the slider up or down to raise or lower the volume. Click the Mute button to mute the sound. 4-32 User's Manual Satellite U500/U500D, Satellite Pro U500/U500D You may see another control under Applications in Volume Mixer. The System Sounds is always displayed since it controls the system sounds' volume. Changing System Sounds System sounds are assigned to inform you when certain events happen. [. . . ] For a screen, it is expressed as the number of pixels available horizontally and vertically restart: Resetting a computer without turning it off (also called "warm boot", "soft reset" or "reboot"). A device that uses three input signals, each activating an electron gun for a primary additive color (red, green, and blue) or port for using such a device. Read Only Memory (ROM): Non-volatile memory that can be read but not written to. Non-volatile here means that information in ROM remains whether or not the computer is receiving power. [. . . ]
