Nowadays, most people take it for granted that they have a reliable and consistent electricity supply

Protecting against power surges
Many people may not be aware that electrical power problems can cause damage to their household electrical equipment and may not therefore, have any equipment in place to protect their most expensive household electrical appliances etc.
There are several ways that you can protect your expensive computer, TV and audio equipment, but the simplest method is to disconnect equipment from the power supply when it is not being used.
A bank of fused electrical expansion sockets or, an extension lead, as they are better known, is a relatively inexpensive piece of equipment that can be used.
Power surges - cost v risk
Over and above that, power surge protection and possibly, power backup equipment becomes more expensive and this is why many people simply don't have any, but this is like playing Russian Roulette with your expensive TV and computer equipment.
Nowadays, most people take it for granted that they have a reliable and consistent electricity supply but, fail to properly protect sensitive electronic equipment and eventually, something will go wrong.
When making a purchase, cost is always a factor, but weigh the cost of replacing an expensive flat screen TV against the cost of electrical protection and.....

One of the main reasons why you may experience Hard Disk Drive data loss

An electrical power surge is quoted as being one of the main reasons why you may experience Hard Disk Drive data loss or, a complete computer crash source but the damage that electrical power surges can do to your computer, isn't just restricted to the problems that they can cause to your computer's Hard Disk Drive.
Repeated or, sustained electrical power surges will almost certainly cause damage to your computer's internal power supply and usually, a power supply that is subjected to increased voltage beyond the limits of its capability, will suffer damage that either: cannot be repaired or, is not cost effective to repair.
Any component that is plugged into your computer's internal power supply (nearly everything) is also, susceptible during a power surge. If you have ever switched your computer on and found that the operating system refuses to start up or, discovered that suddenly, your mouse, keyboard and USB inputs have stopped working, the likely cause is an electrical power supply problem.
As an isolated event, a sudden loss of power to your computer is bad enough, but usually, after such an event, your computer will start up again normally and will not suffer any permanent damage that cannot be rectified. Nevertheless, it is still a good idea to use a UPS (uninterruptible power supply) which will power your computer during a power outage, giving you at least, enough time to power it down normally.
However, if your computer is exposed to sudden power outages regularly which causes your Hard Disk Drives' heads to crash, the damage that this can cause to the heads and/or, the Hard Disk Drives' platters, is not something that can easily be repaired and sometimes, can very easily, result in the Hard Disk Drive being a total loss.
Power brown outs, a dip in the electrical voltage for a sustained period, is just as dangerous for your computer especially, if it is exposed to electrical voltage that repeatedly and rapidly peaks then, troughs. During such an event, it's quite common for some of your operating system's important files to suffer damage or, to be lost altogether.
As with most things, prevention is better and cheaper than the cure and a good UPS and voltage regulator is definitely a worthwhile investment for anyone who owns and uses expensive computer, TV and audio equipment.
Strangely enough, the very first Tic Top Tip article that I wrote on the 7th October 2006 (more than five years ago) was about power supply problems and in it, our readers were advised to purchase and use a UPS, voltage regulator and fused extension lead.
During the last five years, we have lost count of the amount of computers that we have seen that have had issues that were caused by electrical power problems that could have very easily, been avoided, if the computers in question, had been connected to a UPS and/or, a voltage regulator.
As it is the season of good will to all men, I have decided to hide three separate pictures of voltage regulators on our web site. Each of the pictures is accompanied by a question. Find the pictures, answer the questions (by email to competition@ticproblemsolver.com) and win a voltage regulator - there are 3 up for grabs !
The competition closes at midnight on the 26th December 2011. The winners will be the first three readers who submit the correct answers by email. They will be notified by email and their names will be published here in our first article of 2012.
Hot Tip ! - You are looking for a 5 pixel by 5 pixel transparent square in each of the pictures below. Find them with your mouse and click. Each time that you discover one of the hidden squares and click on it, a new window will open containing a question. Send an email to the email address (given above). Put "Competition Entry" in the subject line and your answers to all three questions in the main body of the email - good luck !
Merry Christmas and a Happy New Year to all our readers !
