Caution: Heed This Warning Before Working On Your Computer
Cleaning the hardware or checking the components of your computer require opening the case which may be dangerous to its health. The printed circuit boards inside your computer all contain small devices known as Integrated Circuits (ICs). There can be millions of individual circuits in one IC and they are all susceptible to damage from static electricity. Static electricity is a major contributing factor in the failure of computers. Eliminating damage from Electrostatic Discharge (ESD) leads to untold savings. Below are some things to remember as well as precautions to follow when working 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. A properly grounded wrist strap may be gotten from an electronics store to prevent ESD. Use one of these before touching any components inside such as hard drive, video card, memory stick, etc. If a grounded wrist strap is not available then make sure you touch a grounded object such as a metal pipe to discharge any built up static so you don’t “Shock” your components.
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. Some parts are labeled as “No Serviceable Components Inside” which is not a challenge but a warning because they contain high voltage components which could cause you to hurt yourself if touched. Not all parts of a computer are meant to be repaired such as the power supply. If you determine that a part labeled “No Serviceable Components Inside”, then be smart and just replace it.
Keep in mind that failure to protect yourself can cause injuries and it can also damage your computer and the most common accident is erasing stored data (due to hard drive crash). These are simple things to remember to protect yourself, software, hardware, and most important to protect our precious stored data on our computer.
