107 Learning the Basics Powering down the computer ❖ Avoid exposing 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 benzene or rubbing alcohol). Let the disc dry completely before inserting it in the drive. Powering down the computer Sliding the power switch before shutting down the Windows® operating system could cause you to lose your work. Make sure the system indicator panel's disk light and the drive-inuse light are off. If you turn off the power while a disk is being accessed, you may lose data or damage the disk and/or drive. When you power down the computer, you have a number of options to choose from: ❖ Turn Off or Shut down, which powers 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.
