Believe it or not, electricity is one of the biggest threats to your computer network and the data it contains. Here are four computer power problems you must know about and how to prevent them.TransientsCommonly known as surges and spikes, these are caused by lightning storms, wind, squirrels shorting out power lines, auto accidents, etc.Several times each week these spikes can travel up the power cord into your computer, damaging everything from power supplies to motherboards. Conventional wisdom says use a power strip with a surge protector and you are safe. As usual, conventional wisdom is dead wrong.After a few months, these surge protectors become useless since they’ve been zapped by the surges they were designed to stop.BlackoutsWhether momentary or prolonged, the sudden loss of power can corrupt your PC to the point of not being able to start up again when the lights come back on.SagsThis is when the power drops below normal. Have you ever seen the fluorescent lights flicker for a moment? Then you’ve seen a sag.Sags are more common than surges and are caused when equipment like air conditioners, water heaters or laser printers are turned on or come out of sleep mode. A typical small office will experience 30 or more sags each day.Sags may cause many of the weird and unexplained problems computer users complain about every day.NoiseIf you’ve ever seen a fuzzy picture or white lines on your TV when you turn on a blender or vacuum cleaner, you’ve seen electrical noise. While a fuzzy TV picture is annoyance, this electrical noise causes many computer problems including loss of data.So how do you protect yourself from electrical problems? The most simple and inexpensive solution to all four of these hazards is a battery backup, or uninterruptible power supply (UPS).A UPS can sense when there are problems with the power and automatically switches to the battery, protecting you from computer damage and data loss.Choosing the correct battery backup for your computer or server can be tricky. Having one with a battery too small is the same as having none at all.For most desktop computers, a battery backup with a 500VA or larger rating should be sufficient to keep you going through momentary power problems.Protecting your server requires detailed knowledge of the server functions and power consumption in order to pick the right battery backup.
