around your computer, you should at least get a spill-proof mug or keep the coffee on the other side of the desk. Another enemy of keyboards is static electricity. Static electricity can have the same damaging effect on your keyboard as does liquid. If your keyboard doesn't respond properly after a strong static charge, you may just need to turn off the PC and turn it back on to reset the keyboard. In some cases, however, the static discharge can zap the keyboard and even parts of the PC. If you shuffle your feet across carpet or your PC is in a room with dry air, avoid touching the PC or the keyboard until you have touched something metal to discharge any static. If you don't have a metal desk or bookcase in your work area, consider buying an anti-static mat and keeping it where you can touch it before touching the PC. Dust, dirt, food crumbs, and hair are other enemies of keyboards. Try to avoid eating over the keyboard and if your computer is in a dirty, dusty area, keep the keyboard covered when not in use. Some dirt and dust is unavoidable. To keep the keyboard working well, you should occasionally clean it. Any time you clean the keyboard, turn off the PC first; then try any or all of these three techniques for cleaning the keyboard: 1. Turn it upside down and shake it. This should shake loose some of the crumbs and dirt that collect between the keys. 2. Get a can of compressed air (available for a few dollars at most PC or electronics stores) and use it to blow the dirt and dust from between the keys. Be sure to read the directions on the can before using it. If you hold the can wrong or use it incorrectly, you may blow cold liquid into the keyboard instead of air. Generally, you need to hold the can upright and tip the keyboard up at an angle so the debris will fall out when it is blown loose. 3. If the keys themselves are dirty or sticky, wet a cleaning rag with some rubbing alcohol or a little bit of any non-abrasive household cleaner (something like Windex or Formula 409 is fine) and use it to clean the keys. Don't spray or pour any cleaner directly on the keyboard, and don't get the rag dripping wet. Avoiding Keyboard-Related Injuries Carpal tunnel syndrome, tendonitis, and other repetitive stress injuries have become serious health problems for many computer users. If you will use your computer a lot, you should know how to avoid these injuries and what the symptoms are. First, if you feel any pain after typing or using the PC for extended periods, consult a physician immediately. Symptoms can include:
