If youre going to open up your personal computer case to check some computer hardware components or clean up the hardware you must take the precautions listed. Computer motherboards and components, such as the sound card, video card, and memory, contain very delicate Integrated Circuit (IC) chips. It is necessary to protect computers against damage from static electricity. A brief explanation of static is its a major contributing factor in the breakdown of computers. Eliminating the damage from ESD (Electrostatic Discharge) can save a lot of money. Here are some things you must remember and precautions to follow whenever you work on your computer.
1. After turning off the computer, unplug the power cord to make sure there is no power to the motherboard.
2. Capacitors inside the computer can store an electric charge for a short period of time after turning off and unplugging the computer so it is wise to wait a few minutes after disconnecting the power plug before actually opening the PC case.
3. Use a grounded wrist strap before handling computer components such as the video card, memory, hard disk, and etc. if you do not have one, touch both of your hands to a safely grounded object or to a metal object, such as the power supply case to prevent a discharge from your body to the component.
4. Try not to touch the chips, wires, capacitors or circuitry by holding circuit boards by the edges to avoid static discharge damage.
5. Use a grounded anti-static pad or the bag the component came in to place the components on and prevent static discharge when they are removed from the computer. Avoid dropping your hard drive as it is heavy and will most likely stop working if dropped.
6. Never, ever open items labeled as non-serviceable. Components labeled "No Serviceable Components Inside" are not a challenge because opening them up could lead to serious injury. Some parts of your computer just aren't meant to be repaired. The power supply is one such item and should be replaced if defective, don't attempt to repair it.
Failure to protect yourself can result to injury and also damage to your computer. The most common accident is loss of data caused by a hard drive crash. Remembering these simple things will help to protect you, your hardware, your software and your precious data. - 23802
