92 Learning the Basics Powering down the computer ❖ Do not expose discs to direct sunlight or extreme heat or cold. ❖ To clean a disc that is dirty, wipe it with a clean, dry cloth. The most efficient method to clean it is to start from the center of the disc and wipe toward the outward edge (not in a circle). If necessary, moisten the cloth with water or a neutral cleaner (not benzine or rubbing alcohol). Let the disc dry completely before inserting it in the drive. TECHNICAL NOTE: If you record MP3 files, you will only be able to play them on a device capable of playing MP3 files. Powering down the computer When you power down the computer, you have a number of options to choose from: ❖ Turn Off or Shut down, which power off the computer. ❖ Hibernation, which saves the current operating state to the hard disk and powers off the computer ❖ Standby, which saves the current operating state to memory and enters a low power mode ❖ Restart, which restarts the computer Each option has its advantages. TECHNICAL NOTE: Before using any of these options to power down your computer, save your files and make sure the disk activity lights are off. If you change your mind and decide to continue working after all, wait a few seconds before turning the computer on again.
