When Using Your Computer (continued)

•Clean the display with a soft, clean cloth and water. Apply the water to the cloth; then stroke the cloth across the display in one direction, moving from the top of the display to the bottom. Remove moisture from the display quickly and keep the display dry. Long- term exposure to moisture can damage the display. Do not use a commercial window cleaner to clean your display.

•If your computer gets wet or is damaged, follow the procedures described in “Solving Problems” in your User’s Guide. If, after following these procedures, you confirm that your computer is not operating properly, contact Dell (see “Getting Help” in your User’s Guide for the appropriate contact information).
