Caution:
	Isopropyl alcohol is a flammable liquid. Never spray or pour any liquid directly on the LCD panel. Do not clean the screen while the computer is on.

1. Shut down the computer.
   
   
2. Disconnect power to the system or monitor.
   
   
3. Wipe the LCD screen gently with a soft, dry cloth.
   
   If any marks remain, moisten the cloth with LCD cleaner, and then gently stroke the cloth across the display in one direction, moving from the top of the display to the bottom.

	Notice:
	Do not use any of the following chemicals or any solutions that contain them: acetone, ethyl alcohol, toluene, ethyl acid, ammonia, or methyl chloride. If you have a different chemical or solution and are not sure whether it is suitable, do not use it. Using any of the chemicals in the previous list may cause permanent damage to the LCD screen. Some commercial window cleaners contain ammonia and are, therefore, unacceptable.

4. Be sure the LCD screen is dry before closing it or using the computer.

	Note:
	Many cleaning solutions are sold specifically as LCD cleaners. You can use these to clean LCD screens on Dell laptops. Alternately, you may use a 50/50 isopropyl alcohol and water mixture. Microfiber cloths such as those used to clean eyeglasses are excellent for use with LCDs.
