People often think it is very dangerous to play with electrical items and this should be done by a professional. This is true, however now days everyone has their hands, literally, inside a computer case.
Different cases open in different ways. For example a desktop may have two clips or buttons on either side, and when pressed, the case slides off. A tower may need to have screws removed at the back to enable the sides to slide off. Cases are now being designed with easy access as a top priority.
There was always the idea that you needed an antistatic strap before opening a computer case. This is undoubtedly is the safest way to do this, however there are other options. Here are a few tips from a self confessed, no frills, computer techie.
1.Remove all power cords that are connected to the computer case. This includes network cables, modems, printers, everything...Wait a few seconds as the power leaves the mainboard.
2. Make sure your hands are clean and definitely DRY. Remove all jewelry.
3.Open your computer case by unscrewing or unclipping. See your computer manual for instructions if you have problems. Older computers can be difficult to open. Keep an screws or spare parts in a safe place.
4.To protect your computer from static electricity stored on your body, (ESD) continually touch the unpainted metal part of the case to discharge any static. Or if you have a antistatic or grounding strap, use that. This will prevent the static.
5.Ok. Now you are ready to work on the insides of your computer.
