Dust, cigarette ash, pet hair, and other particles can accumulate on or inside the notebook PC. 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 PC can extend its life by getting rid of this potentially damaging buildup. Cleaning the system once a year as part of a regular maintenance program is recommended.
Clean the Cooling Vents
Depending on the model, vents can be found on the side, back, and/or bottom of the notebook PC. These vents allow air to flow through the PC 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.
Clean I/O Ports
The back of the notebook PC 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, then wipe the screen with it.
| CAUTION: | Never spray or pour any liquid directly on the LCD panel. Do not clean the screen while the system is on. |
| NOTE: | 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.
