HP Notebook PCs - Cleaning your Notebook PC

This document pertains to all HP and Compaq Notebook PCs.
This document tells you how to clean your notebook computer. Dust, cigarette ash, pet hair, and other particles can accumulate on or inside the notebook computer. When this happens, they form a layer of grime that can scratch or shorten the life of hardware components by causing overheating. Cleaning the notebook computer can extend its life by getting rid of this potentially damaging buildup. It is recommended to inspect your system for cleanliness once a month as part of a regular maintenance program.
Before cleaning the notebook computer, perform these steps to reduce the risk of electrical shock:
  1. Turn off the computer.
  2. Unplug the power cord from the computer.

Clean the Cooling Vents

Depending on the model, vents can be found on the side, back, and/or bottom of the notebook computer. These vents allow air to flow through the computer and keep it cool. Buildup inside these vents impedes the cooling process. Purchase a can of compressed air (available at most computer retailers) and blow the particles out of the vents. See Reducing Heat Inside the PC for more information about cleaning the cooling vents.

Clean I/O Ports

The back of the notebook computer has a series of ports. After cleaning the cooling vents, take the compressed air and blow out any debris that may have accumulated in and around these ports.

Clean the Display

LCD screens accumulate smudges and scratches all the time. To clean these, choose a non-abrasive cloth or towel. Shut the computer off and disconnect the power cable. 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. Plastic and glass cleaners containing ammonia may leave a glare-causing film, so use a computer monitor specific cleaner from a computer store. Spray the cleaner onto the cloth, and then wipe the screen with it.
  • Isopropyl Alcohol is a flammable liquid.
  • Never spray or pour any liquid directly on the LCD panel.
  • Do not clean the screen while the system is on.
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.
Be sure the LCD screen is dry before closing it or using the computer.

LCD Maintenance

Follow these tips to avoid damage to the LCD display.
  • Do not place anything heavy on the notebook.
  • When using a carrying case or backpack, do not overstuff the carrying case. This can apply extra pressure to the notebook case and LCD back.
  • Do not scratch, twist or hit the surface of the LCD screen.
  • Avoid subjecting the LCD screen to extremes of temperature and humidity.
  • Avoid exposing the LCD screen to direct sunlight or strong fluorescent light for long periods of time.
  • Avoid hard physical shocks to the system.

Clean the Keyboard

If a small vacuum cleaner with a brush attachment is available, use it to clear the keyboard of debris. A can of compressed air can be used to blow out particles that get in between the keys.
