Time for spring cleaning here is a tip for computers
1.When cleaning a component or the computer, turn it off before cleaning.And unplug it
2.When cleaning, be careful not to accidentally adjust any knobs or controls. In addition, when cleaning the back of the computer, if anything is plugged in, make sure not to disconnect any of the plugs.
3.When cleaning fans, especially the smaller fans within a portable computer or laptop it's suggested that you either hold the fan or place something in-between the fan blades to prevent it from spinning. Spraying compressed air into a fan or cleaning a fan with a vacuum may cause damage or back voltage to be generated.
4.Cloth - A cloth is the best tool used when rubbing down a component; although paper towels can be used with most hardware, we recommend using a cloth when ever possible. Caution: We only suggest you use a cloth when cleaning components such as the outside of the case, a drive, mouse, etc. You should not use a cloth to clean any circuitry such as the RAM or motherboard since they can generate ESD that can damage electronics.
5.Portable Vacuum - Sucking the dust, dirt, hair, cigarette particles, and other particles out of a computer can be one of the best methods of cleaning a computer. Over time, these items can restrict the airflow in a computer and cause circuitry to corrode. Do not use a standard vacuum as it can generate a lot of static electricity that can damage your computer.
Why? Keeps the appearance of the computer looking new. During cleaning, if ventilation locations are found, these can be cleaned helping the case keep a steady airflow to the computer, keeping components cool and in good working condition.
Procedure: The plastic case that houses the PC components can be cleaned with a lint-free cloth that has been slightly dampened with water. For stubborn stains, add a little household detergent to the cloth. It is recommended that you never use a solvent cleaner on plastics.
Make sure all vents and air holes are hair and lint free by rubbing a cloth over the holes and vents. It is also helpful to take a vacuum around each of the hole, vents, and crevices on the computer. It is safe to use a standard vacuum when cleaning the outside vents of a computer; however, if you need to clean the inside of the computer, use a portable battery powered vacuum to prevent static electricity.
CD-ROM, DVD, and other disc drive cleaning
Why? A dirty CD-ROM drive or other disc drives can cause read errors when reading discs. These read errors could cause software installation issues or issues while running the program.
Procedure: To clean the CD-ROM drive we recommend purchasing a CD-ROM cleaner from your local retailer such as a local Radio Shack. Using a CD-ROM cleaner should sufficiently clean the CD-ROM laser from dust, dirt, and hair.
In addition to cleaning the drive with a special disc designed to clean drives users can also use a cloth dampened with water to clean the tray that ejects from the drive. Make sure however that after the tray has been cleaned that it completely dry before putting the tray back into the drive.
Why? Dirt, dust, and finger prints can cause the computer screen to be difficult to read.
Procedure: Unlike a computer monitor, the LCD / flat-panel display is not made of glass, therefore requires special cleaning procedures.
When cleaning the LCD screen it is important to remember to not spray any liquids onto the LCD directly, press gently while cleaning, and do not use a paper towel as it may cause the LCD to become scratched.
To clean the LCD screen we recommend that you use a non-rugged microfiber cloth, soft cotton cloth, or Swiffer duster. If a dry cloth does not completely clean the screen, you can apply rubbing alcohol to the cloth and wipe the screen with the damp cloth. Rubbing alcohol is used to clean the LCD before it leaves the factory.
