Cleaning the Tablet PC Dust, dirt, pet hair, and other particles can accumulate on or inside the Tablet 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 Tablet 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 Tablet 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 nonabrasive cloth or towel. Plastic and glass cleaners containing ammonia may leave a glarecausing 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. 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.
